4.
Don't get caught in moving parts. Before operating this machine remove all
jewellery including watches and rings, neckties, and any loose-fitting clothing.
5.
Keep your hair away from moving parts. Wear adequate safety headgear.
6.
Protect your feet. Wear safety shoes with oil-resistant, anti-skid soles, and
steel toes.
7.
Take off gloves before you start the machine. Gloves are easily caught in
moving parts.
8.
Remove all tools (wrenches, check keys, etc.) from the machine before you
start. Loose items can become dangerous flying projectiles.
9.
Never operate a milling machine after consuming alcoholic beverages, or taking
strong medication, or while using non-prescription drugs.
10. Protect your hands. Stop the machine spindle and ensure that the CNC control
is in the stop mode:
• Before changing tools
• Before changing parts
• Before you clear away the chips, oil or coolant. Always use a chip
scraper or brush
• Before you make an adjustment to the part, fixture, coolant nozzle or
take measurements
• Before you open safeguards (protective shields, etc.). Never reach for
the part, tool, or fixture around a safeguard.
11. Protect your eyes and the machine as well. Don't use a compressed air hose to
remove the chips or clean the machine (oil, coolant, etc.).
12. Stop and disconnect the machine before you change belts, pulley, gears.
13. Keep work area well lighted. Ask for additional light if needed.
14. Do not lean on the machine while it is running.
15. Prevent slippage. Keep the work area dry and clean. Remove the chips, oil,
coolant and obstacles of any kind around the machine.
11
XYZ Machine Tools, Ltd.
XYZ Turret Mill & ProtoTRAK ® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
16. Avoid getting pinched in places where the table, saddle or spindle head create
"pinch points" while in motion.
17. Securely clamp and properly locate the workpiece in the vise, on the table, or in
the fixture. Use stop blocks to prevent objects from flying loose. Use proper
holding clamping attachments and position them clear of the tool path.
18. Use correct cutting parameters (speed, feed, depth, and width of cut) in order
to prevent tool breakage.
19. Use proper cutting tools for the job. Pay attention to the rotation of the spindle:
Left hand tool for counterclockwise rota tion of spindle, and right hand tool for
clockwise rotation of spindle.
20. Prevent damage to the workpiece or the cutting tool. Never start the machine
(including the rotation of the spindle) if the tool is in contact with the part.
21. Check the direction (+ or -) of movement of the table when using the jog or
power feed.
22. Don't use dull or damaged cutting tools. They break easily and become
airborne. Inspect the sharpness of the edges, and the integrity of cutting tools
and their holders. Use proper length for the tool.
23. Large overhang on cutting tools when not required result in accidents and
damaged parts.
24. Prevent fires. When machining certain materials (magnesium, etc.) the chips
and dust are highly flammable. Obtain special instruction from your supervisor
before machining these materials.
25. Prevent fires. Keep flammable materials and fluids away from the machine and
hot, flying chips.
26. When working in manual mode (not CNC) make sure the computer control is
switched to DRO or OFF.

3.1.2 Advanced Features Option
The Advanced Features Option may be purchased with the original order or purchased
later. Note, the Advanced Features Option is included in the ProtoTRAK Offline
Software, but must be purchased separately for each ProtoTRAK SMX CNC.
It is easy to tell if you have the Advanced Features Option. If you have the Advanced
Features Option, the features listed below will be active. If you do not, the features
listed below will not be active and any Softkey for that feature will be grayed out. For
example, in the Program Mode, under Pocket, check the Softkey labeled IRREG PCKT. If
the words “IRREG PCKT” are black, the Advanced Feature Option is active. If they are
gray, the Advanced Feature Option is not active.
The other way to tell if the Advanced Features Option is active is to go to Service Code
318. The Advanced Features Option is active if the letters are in black, inactive if they
are in gray.

The coolant pump is mounted in the back of the machine column. It is plugged into the
electrical cabinet and is configured to operate as commanded by the accessory key.
3.12 Chip Pan
The Chip Pan fits around the base of the mill to collect coolant and chips.
3.13 Table Guard
The Table guard provides an enclosed workspace mounted on the table. The doors
are switched to prevent the machine spindle starting in any mode if they are open. It
also prevents the operation of the CNC in Run mode with the door open. While it will
aid in the control of chips and coolant, it is not a full, waterproof enclosure. Removal of
these guards is prohibited by law. They are fitted for the benefit of the machine
operator and to comply with the current legislation, removal means you are breaking
the law.
3.14 Z-Axis Ballscrew and Motor Assembly
For three-axis CNC models, a Z-axis ballscrew and motor assembly is mounted on the
head using two tramming bolts and the fine feed boss.
In manual and CNC operations, the quill is moved by a servo motor connected by a belt
to a ballscrew. The ball nut of the ballscrew is attached to fork that engages the quill in
the threaded hole previously used by the quill stop knob.
In CNC operations, the motor is controlled by the CNC program.
In manual operations, the motor is controlled by jog commands from the user and by
the operation of the electronic handwheel.
A limit switch in the assembly prevents damage from over travel. Z-axis traverse is
limited to 115mm.
3.15 Limit Switches
Limit switches are mounted for the saddle and table travel.
3.16 Optional Equipment
3.16.1 Electronic Handwheels
When ordered as part of the TRAKing/Electronic Handwheels Option (see Section 3.1.6)
the electronic handwheels replace the standard mechanical handwheels for table and
saddle traverse. The electronic handwheels will operate when the ProtoTRAK SMX CNC
is in a Mode where the machinist controls the motion of the table and saddle. This
includes the DRO Mode, the Set-Up Mode and the TRAKing operation in the Run Mode.
The electronic handwheels will not operate during other functions, such as when the
“Select a Mode” message appears on the screen.
Handwheel resolution is determined by the F/C key on the display. Fine feed moves
5mm (0.200 inches) per revolution, Course feed moves 20mm (0.800 inches) per
revolution.
3.16.2 Linear Scales
27
XYZ Machine Tools Ltd.
XYZ Turret Mill & ProtoTRAK ® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
The ProtoTRAK SMX CNC may be configured to run either with or without Linear Scales
for X and Y travel. Linear scales have a feedback resolution of 5 Microns.
3.16.3 Power Draw Bar
A manual draw bar comes standard with the machine. A power draw bar option may
be ordered. For the SMX 3000, and SMX SLV machines, the draw bar included in the
option may be M16 or 5/8 UNC.
The standard type of power draw bar is of the appropriate length to fit tool holders that
have a threaded tang on the top ( ISO 40). BT40 and CAT 40 tool holders have a
different arrangement at the small tapered end so a longer drawbar is required to
thread into the tool holder when the retention knob is removed. These longer drawbars
can be provided on request please talk to your Area Sales Manager or XYZ Machine
Tools parts department.
3.16.4 Remote Stop Go Switch
For the convenience of operation while running the program, a Remote Stop/Go switch

4.0 Basic Operation
The ProtoTRAK SMX CNC combines the simplicity and flexibility of using a knee mill with the
easy, natural user interface that makes the ProtoTRAK the top brand in CNCs for small lot
machining.
4.1 ProtoTRAK SMX Basic Operation.
Most of the operations of the ProtoTRAK SMX CNC are organized in Modes. Modes are logical
groups of activities that naturally belong together. This eliminates the need to memorize
operations – just select a mode and choose among the soft keys.
Most operations will be discussed within the section that treats the particular mode later in this
manual. The operations described in this section either don’t fit in a particular mode, or they
are relevant to more than one mode.
4.1.1
Switching on the ProtoTRAK SMX CNC
To turn the ProtoTRAK SMX CNC on, move the toggle switch on the display side panel to the Up position.
The Windows operating system and the ProtoTRAK SMX CNC software will take a few seconds
to load from the system's flash memory. If you have connected the ProtoTRAK SMX CNC to a

CAUTION!
Never attempt to change the range selection through the High-Low -Neutral lever when the
spindle is rotating. Be certain the spindle ON/OFF switch is in the Off position.
Rotate the spindle by hand to help engage the lever into the high or low
position.
Note: Shifting from the high to low range, or low to high range changes the direction of rotation
for the On/Off switch (See Section 4.2.1).
4.2.7
Speed Changes
For the standard vari-speed head, spindle speed may be varied by rotating the variable
speed crank. When the Programmable Electronic Head Option is installed, the spindle
speed is controlled by the ProtoTRAK SMX CNC. See the instructions in the Program
Mode, DRO Mode and Run Mode.
CAUTION!
Do not rotate the variable speed crank when the spindle is stationary.
4.2.8
Operating the Quill
For two-axis CNC models, the quill may be moved up and down through its range with
the quill feed handle. The quill may be locked into position by rotating the quill lock
clockwise. Pull the handle out slightly to rotate it freely to a new position.
For three-axis CNC models, the quill is operated by the electronic handwheel mounted
on the side of the Z Ballscrew and Motor Encoder.
Note: sections 4.2.9 through 4.2.15 refer to two-axis CNC models.

5.0 Definitions, Terms & Concepts
5.1 ProtoTRAK SMX CNC Axis Conventions
X Axis: positive X-axis motion is defined as the table moving to the left when facing
the mill. Consequently, measurement to the right is positive on the workpiece.
Y Axis: positive Y-axis motion is defined as the table moving toward you. Measurement
toward the machine (away from you) is positive on the workpiece.
Z Axis: positive Z-axis motion is defined as moving the head up. Measurement up is
also positive on the workpiece.
FIGURE 5.1 ProtoTRAK SMX CNC conventions
The Z RAPID dimension is the position at which Z will stop rapid traversing and switch to
its programmed Z feedrate. Z motion will continue until Z End depth has been reached.
5.2 Part Geometry & Tool Path Programming
The ProtoTRAK SMX CNC gives you ultimate flexibility in programming. Programs that
are entered through the ProtoTRAK SMX CNC system can be entered as either Part
Geometry or Tool Path (optional).
Part Geometry programming is the popular programming style of the ProtoTRAK family
of products. This is done by defining the final geometry of the part, and the ProtoTRAK
SMX CNC has the job of figuring out the tool path from the part dimensions and the tool
set-up information. This is a great benefit compared to regular CNC because it doesn't
force the programmer to do the difficult job of defining tool path. A consequence of
part geometry programming is that the following are not allowed:
• connection of an incline plane and another event
• connection of two events that lie in different planes
Using Geometry Programming, it is impossible for the ProtoTRAK SMX CNC to calculate
a tool path for these cases without creating a problem: in cutting the geometry desired
in the first event, the tool ends up out of position for the next event. Resolving the
difference in tool position where the first event ends and the next event begins means
either the CNC calculates and makes an unprogrammed move, or it retracts the tool out
and then back into the part.
These cases are not encountered often, but when they are you have the option of using Tool
Path programming. In Tool Path programming you define the events the same way, but all
inputs are treated as tool center. It is your job to calculate and program the tool path.
Note: Tool Path programming is part of the Advanced Features Option.
39
XYZ Machine Tools, Ltd.
XYZ Turret Mill & ProtoTRAK ® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
Programs generated by CAD/CAM systems are always generated as Tool Path programs and are
run as such even if the Advanced Features Option has is not active on the ProtoTRAK S MX CNC.
5.3 Planes and Vertical Planes
A plane is any flat surface. If that surface lies flat on the table, it is the XY plane. That is, if you
move your finger along that surface or plane, you are moving in the X and/or Y direction, but not
in Z (or at least not until you pick your finger up). If you tilted that surface (think of it as a piece
of paper) straight up so that it faces the front of the machine, it would be in the XZ plane. If you
tilted it up so that it faced left or right, it would be in the YZ plane.
A vertical plane is any plane (or surface) tipped up on its edge on the table (see below).
Programming vertical planes requires the Advanced Features Option (Section 3.1.2).
Unlike most CNC controls,
the ProtoTRAK SMX CNC can
machine arcs in any vertical
plane rather than just XZ or YZ.
FIGURE 5.3 Vertical Planes
5.4 Absolute & Incremental Reference
The ProtoTRAK SMX CNC may be programmed and operated in either (or in a combination) of
absolute or incremental dimensions. An absolute reference from which all absolute dimensions
are measured (in DRO and program operation) can be set at any point on or even off the
workpiece.
To help understand the difference between absolute and incremental position, consider the
following example:
FIGURE 5.4 Each point has both an absolute and an incremental reference in the X axis.
The ProtoTRAK SMX CNC allows you to program using either.
5.5 Referenced & Non-Referenced Data
Data is always loaded into the ProtoTRAK SMX CNC by using the INC SET or ABS SET
key. X, Y, Z positions are referenced data. In entering any X, Y, or Z position data, you
must note whether it is an incremental or absolute dimension and enter it accordingly.
All other information (non-referenced data), such as tool diameter, feedrate, etc. is not
a position and may, therefore, be loaded with either the INC SET or ABS SET key. This
manual uses the term SET when either INC SET or ABS SET may be used
interchangeably.
5.6 Incremental Reference Position in Programming
40
XYZ Machine Tools, Ltd.
XYZ Turret Mill & ProtoTRAK ® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
When X, Y, Z RAPID and Z data for the beginning position of any event are input as
incremental data, this increment must be measured from some known point in the
previous event. Following are the positions for each event type from which the
incremental moves are made in the subsequent event:
Position: X, Y and Z programmed
Drill: X, Y, Z RAPID, and Z END programmed
Bolt Hole: X CENTER, Y CENTER, Z RAPID and Z END programmed
Mill: X END, Y END, Z RAPID and Z END programmed
Arc: X END, Y END, Z RAPID and Z END programmed
Circle (POCKET or FRAME): X CENTER, Y CENTER, Z RAPID and Z END programmed
Rectangle or Irregular (POCKET or PROFILE): X1 and Y1 corner, Z RAPID and Z
END programmed
Helix: The X END, Y END, Z RAPID, and Z END programmed. Helix programming
requires the Advanced Features Option.
Sub: The reference position as defined for the specific events above for the event prior
to the first event that was repeated.
A.G.E. PROFILE: The appropriate reference position as defined for the specificevents
above for the last event that is programmed. A.G.E. Profile Programming requires the
Advanced Features Option.
For example, if an ARC event followed a MILL event, a 50mm incremental X BEG would
mean that in the X direction the beginning of the ARC event is 50mm from the end of
the MILL event.
5.7 Tool Diameter Compensation
Tool diameter compensation allows the machined edges shown directly on the print to
be programmed instead of the center of the tool. The ProtoTRAK SMX CNC then
automatically compensates for the programmed geometry so that the desired results
are obtained. Tool cutter compensation is always specified as the tool either right or
left of the workpiece while looking in the direction of the tool motion.
FIGURE 5.7.1 Examples of tool right
41
XYZ Machine Tools, Ltd.
XYZ Turret Mill & ProtoTRAK ® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
FIGURE 5.7.2 Examples of tool left
Tool center means no compensation either right or left. That is, the centerline of the
tool will be moved to the programmed points.
5.8 Tool Diameter Compensation when Contouring in Z
with Part Geometry
Note: Z contouring requires the Advanced Features Option (Section 3.1.2)
Left and right tool diameter offsets are always those projected into the XY plane. Tool
offsets in the Z direction are always up and assume the use of a ball end mill. When
contouring in the Z-axis, this up tool offset is always activated regardless of left, right,
center if the Part Geometry option is selected. There is no Z-axis up tool offset applied
when the Tool Path option is selected.
Special atte ntion must always be paid to tool offsets when machining with a ball end
mill. The reason for this is that the tool diameter changes in the bottom part (that
portion equal to the tool radius) of the tool.
The tool is always positioned at the beginning of a milling operation so that the correct
point on the ball end of the tool is tangent to the beginning point, and offset perpendicular to the machined edge by the radius of the tool. Consider the example below of
milling a ramp in the XZ plane from point B to point C.
FIGURE 5.8.1 Ball end mill position with respect to program points. Tool starts so end mill is
tangent to BC. R from center of tool is perpendicular to BC
Note how the tool at the beginning point (point B) starts below (in the Z direction) point
B so that it can actually touch this point. If this were not true, a cusp would remain to
the left of point B.
Now consider a similar example milling from A to B to C in the XZ plane.
42
XYZ Machine Tools, Ltd.
XYZ Turret Mill & ProtoTRAK ® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
FIGURE 5.8.2 In order to respect the lines defined by the programmed points, the ball
end mill never touches point B. Tool starts centered over A offset up by the tool radius R.
It moves right until it is tangent to both AB and BC. Then moves to point C as in the first
example
Note the Tool at B does not drop below the AB line and, therefore, never touches point
B. As a result, a fillet is formed at point B equal to the tool radius.
This second example of continuous machining from one cut (AB) to another (BC) with
full cutter compensation between requires the two cuts to be made with events which
are connective (see Section 5.9 or 5.10 for a more complete discussion of this
requirement).
5.9 Connective Events
Connective events occur between two milling events (either Mill or Arc) when the X, Y, and Z
ending points of the first event are in the same location as the X, Y, and Z starting points of the
next event. In addition, the tool offset and tool number of both events must be the same. And
both events must lie in the XY plane or the same vertical plane (see Section 5.2).
5.10 Conrad
Conrad is a unique feature of the PROTOTRAK SMX CNC that allows you to program a
tangentially connecting radius between connective events, or tangentially connecting radii for the
corners of pockets and frames without the necessity of complex calculations.
For the figure below, you program an Arc event from X1, Y1 to X2, Y2 with tool offset left, and
another Arc event from X2, Y2 to X3, Y3 also with tool offset left. During the programming of
the first Arc event, the system will prompt for Conrad at which time you input the numerical
value of the tangentially connecting radius r=K3. The system will calculate the tangent points T1
and T2 and direct the tool cutter to move continuously from X1, Y1 through T1, r=k3, T2 to X3,
Y3.
FIGURE 5.10.1 A Conrad is added between the two intersecting
lines
Note: Conrad must always be the same as or larger than the tool radius for inside corners. If Conrad
is less than the tool ra dius, and an inside corner is machined, the ProtoTRAK SMX CNC will ignore
the Conrad.
43
XYZ Machine Tools, Ltd.
XYZ Turret Mill & ProtoTRAK ® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
For the figure below, you program an Arc event from X1, Z1 to X2, Z2, and a Mill to X3, Z3.
During the programming of the Arc event, the system will prompt for Conrad at which time you
input the numerical value of the tangentially connecting radius r=k. The system will calculate
the tangent points T1 and T2 and direct the tool cutter to move continuously from X1, Z1
through T1, r=k, T2 and on to X3, Z3.
FIGURE 5.10.2 A Conrad is added between an arc and a
line
5.11 Memory & Storage
Computers can hold information in two ways. Information can be in current memory
or in storage. Current memory (also known as RAM) is where the ProtoTRAK SMX
CNC holds the operating system and any part program that is ready to run. While a
program is being written, it is in current memory.
For the base system of the ProtoTRAK SMX CNC, storage of programs is on a disk in the
floppy drive. We strongly recommend you habitually back up programs.
When the Network/Memory Option is purchased, program storage can be on a floppy
disk, on the 128MB (or higher) flash drive that comes with the option, or on an offline
computer that is networked to your SMX CNC.

6.6 Go To (TRAKing/Electronic Handwheels Option)
The Go To function in the DRO mode allows you to set a dimension in X, Y or Z at which
you want the machine to stop moving when you are cranking manually. For example, if
you wanted to machine manually exactly 5omm of table motion, you would input: Go To,
X, 50, Inc Set. While the Go To window is displayed, the ProtoTRAK SMX will not let
you pass that 50mm dimension you set.
a. Press the Go To key.
b. Enter the axis, X, Y, Z or any combination. Input the dimension(s).
c. Press Inc Set or Abs Set.
d. Crank the handwheel. Motion will stop at the entered dimension even if you continue
to crank the handwheel.
6.6.1
Go To for Three-Axis CNC Models
Whether or not the TRAKing/Electronic Handwheels Option is active, XYZ Turret Mills
with the Z-axis ballscrew and motor assembly installed for three-axis CNC will have this
feature enabled for manual quill operation. Simply follow the instructions above. If the
TRAKing/Electronic Handwheels Option is not active, only the Z will be available for
setting a Go To dimension.
6.7 Teach
Teach gives you the ability to enter X and Y dimensions into a program. It can be a
useful way of entering a few manual moves for operations like clearing out excess
material or remembering a few hole locations.
The process of using Teach is in two parts. The first part takes place in the DRO Mode.
This is where you start the Teach program, establish the program events and enter the
X and Y dimensions. The second part is in the Program Mode. This is where you
complete the Teach events that you began in the DRO Mode by entering the rest of the
data. Once the data is entered, the Teach events become just like the other events that
make up a program.
6.7.1
Entering Teach Data
From the DRO screen, press Teach.
On the top of the screen, you will see the message "Teach" and an event counter.
When you enter Teach, you are actually programming events. If there is already a
program in current memory, Teaching will add events to the end of the program. If
there is not already a program in current memory, Teaching will start a new program.
For example, if you already had a program in current memory that had 10 events, when
you press Teach, the event counter will say EVENT 11. If there was no program, the
event counter will say EVENT 1.
The event counter shows the event for which data is being entered. You may teach in
position, drill and mill events only.
On the first Teach screen, the softkeys are:
POSN: a position move. For two-axis programming, the POSN and DRILL events are combined.
DRILL: a drill or bore.
MILL BEGIN: the beginning of a straight line or MILL event.
END TEACH: ends the teaching process and returns you to the main DRO screen.
If you press the POSN or DRILL key, the event counter will go up by one and the screen
remains the same. If you press the MILL BEGIN key, the event counter stays on the
47
XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK SMX CNC Safety, Programming, Operating & Care Manual
same number. That is because you have given the beginning point of the line but not
yet the end. The softkey selections will change to:
MILL END: the last point of the Mill event. Press this to end the Mill event and select a
POSN, DRILL or new MILL event.
MILL CONT: the last point of the current Mill event, but the beginning of the next Mill
event. You may enter successive Mill events by pressing the MILL CONT key.
Pressing either of the above softkeys will cause the event counter to increase by one.
At any time you may exit the Teach and return to the DRO screen. The events you have
defined with their X and Y dimensions are finished in the Program Mode. See Section 8.14.
6.8 Return To Absolute Zero
At any time during manual DRO operation you may automatically move the table to your
absolute zero location in X and Y by pressing the RETURN ABS 0 soft key. When you
do, the message window will read "Ready to Begin: Press Go when Ready”. Make sure
your tool is clear and press the GO key. The servos will turn on, move the quill to Z
retract (for three-axis CNC models) then move the table at rapid speed to your X and Y
absolute zero position, and then turn off. You will be at zero and in manual DRO
operation.
6.9 Tool #
The ProtoTRAK SMX CNC allows you to use the data for tools in your Tool Table (see
Section 11.1) in the DRO Mode. To change tools, press the TOOL # soft key and enter
the tool number when prompted by the Data Input Line.
Even when you set up a tool in the Set-Up Mode, if you do not wish to use the tools in the
Tool Table, simply ignore the Tool # feature.

7.0 Program Mode
Getting Started & Some General Information
7.1 Programming Overview
The ProtoTRAK SMX CNC makes programming easy by allowing you to program the
actual part geometry as defined by the print.
The basic strategy is to first fill in the initial program information in the Program Header
screen and then program the features of the part by selecting the soft key event types
(geometry) and then follow all instructions in the Data Input Line.
When an event is selected, all the prompts that need to be input will be shown on the
right side of the screen. The first prompt will be highlighted and also shown in the Data
Input Line. Input the dimension or data requested and press INC SET or ABS SET. For
X or Y dimension data it is very important to properly select INC SET or ABS SET. For
all other data either SET will do.
As data is being entered it will show in the Data Input Line. When SET, the data will be
transferred to the list of prompts in the right side of the screen, and the next prompt will
be shown in the Data Input Line.
When all data for an event has been entered, the entire event will be shifted to the left
side of the screen and the conversation line will ask you to select the next event.
7.2 Enter Program Mode
Press MODE, select PROGRAM soft key.
The ProtoTRAK SMX CNC will allow only one program in current memory. To write a
new program, you must first erase the one in current memory (you may want to first
store the program for use in the future). If there is already a program in current
memory, entering the Program mode will allow you to edit or add to that program.
FIGURE 7.2 The Program Mode header screen. Most selections
above relate to the Advanced Features Option. If your screen shows
only Program Name and Dwell, The Advanced Features Option is not
active.

7.3 Program Header Screen
The first screen you see when you enter the Program Mode is the Program Header
Screen. The Program Header Screen gives you options that apply to the entire
program. The softkey selections allow you to ente r the program at any point.
The program name and general programming options you choose in the Program
Header Screen will be summarized in the program as "Event 0".
7.3.1
Program Name
Programs written on the ProtoTRAK SMX CNC are usually named for the part that is to
be machined. When programs (or files) are named using the ProtoTRAK SMX CNC, the
name can be up to 20 characters long. Programs imported into the ProtoTRAK SMX
CNC may be longer. While 20 characters are allowed, the entire program name may
not be shown in the status line or the program header screen.
FIGURE 7.3 Pressing the Help hard key when the Program Name is highlighted calls up alpha
keys
Program names can include numbers, letters, spaces and other characte rs. When the
Program name prompt is highlighted, the Data Input Line will show "Program Name:".
At this point you may:
•
•
•
Press number keys.
Press Help to access alpha keys and special characters in the ProtoTRAK SMX
CNC.
Use a keyboard plugged into the ProtoTRAK SMX CNC to name the program.
To use the alpha keys and special characters on the ProtoTRAK SMX CNC:
Use the Clear softkey to erase the entire line; the Backspace softkey to erase the last
character or number.
•
Use the arrow softkeys to move around the table.

•
Once the character you want is highlighted, use the Enter softkey to load the
character into the program name.
Use the blank space on the lower right of the table to insert a space into the
program name.
Once you finish entering the letters and special characters, press the End softkey.
This tells the ProtoTRAK SMX CNC that you are finished with the alpha table.
Numbers may still be added to the program name.
When you are finished with the program name, press SET to enter it into the current memory.
Note: It is not necessary to enter a part number. If none is entered and a GO TO soft key is
pushed, the system will assume a part number 0.
7.3.2
General Program Options
Use the DATA FWD softkey to select general programming options. See Section 3.1.2
for more information about the Advanced Features Option.
Scale : Allows a scale factor between .1 and 10. An input of 5 means the part will be 5
times as big as the programmed dimensions. A value of 1.0000 is assumed if nothing is
input. This function is part of the Advanced Features Option.
Dwell Request: For three-axis CNC machining only. Allows you to input a dwell at the
bottom of a drill, bolt hole or bore cycle for events you select. Select the appropriate
YES or NO soft key. If you select YES you will be prompted to input a dwell time in
seconds from .1 to 99.9 when appropriate to the event being programmed.
Auxiliary Function Request: Asks if you wish to activate any of the optional auxiliary
functions (see Section 7.4) at any time during the program. Select the appropriate YES
or NO soft key. If you select YES you will be prompted to input the type and sequencing
of the auxiliary functions during event programming. Auxiliary Functions are optional for
three-axis CNC models only.
Event Comments: If you select "Yes" for event comments, you will have the
opportunity to insert a comment in each event. For Irregular Pocket and Irregular
Profile events, you will be able to enter a comment at the header event, but not for each
A.G.E. Turn and A.G.E. Arc event. This function is part of the Advanced Features
Option.
Comments appear in the RUN mode on the Data Input Line as the event begins to run.
Comments may be composed of letters, numbers and some symbols and may be up to
20 characters.
While programming the event with the Event Comments set to Yes, when the highlight is
on the Event Comments prompt, you may enter a comment using the same methods
used to enter a program name, as described above.
Multiple Fixtures: Asks you if you wish to turn on the multiple fixtures offset.
Answering Yes will cause a prompt to appear at each event asking which fixture the
event was referenced from. If you select Yes, the Data Input Line will ask you to enter a
fixture default number from one to six. The fixture default number is the fixture that will
be applied to all the events in current memory when Multiple Fixtures is turned on or
when a new event is programmed without another event being specified. Enter the
default fixture, or leave the number unchanged, and press SET. Multiple Fixtures are
explained more fully in Section 7.5. This function is part of the Advanced Features
Option.
Dimension Definition: The ProtoTRAK SMX CNC gives you a choice in programming either
tool path or geometry. Part Geometry programming allows you to define the geometry you
want your part to have and then the CNC does the difficult job of calculating tool path for
you automatically. This is a great benefit for most parts most of the time because it means
that the CNC is doing the hard work of determining tool position.

XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
One restriction to part geometry programming is that for events to be connective, they
must lay on the same plane (see Section 5.3 for a definition of planes). For this reason,
the ProtoTRAK SMX CNC gives you the option of entering your own tool path. If you
wish to program the part by defining tool path yourself, you may choose the TOOL PATH
softkey. Otherwise, Part Geometry programming is assumed. Tool Path operates under
the same rules as standard RS274.
A program must be entirely written in Part Geometry or Tool Path programming, you
cannot combine the two methods in one program. Tool Path programming is part of the
Advanced Features Option.
7.3.3
Program Header Softkeys
The following softkeys are encountered in the Program Header Screen. The first five
listed below are always there. The last four appear when relevant to the general
programming option.
DATA FWD: moves the highlight forward through the programming options without
setting an input into the program.
DATA BACK: moves the highlight backward through the programming options without
setting an input into the program.
GO TO BEGIN: puts the Program Header on the left side of the screen and the first event
on the right side.
GO TO END: puts the last programmed event on the left side of the screen and the next
event to be programmed on the right side.
GO TO #: enter the event number you wish to go to and then press SET. Puts the
requested event number on the right side of the screen and the previous event number
on the left.
Note: for a new program that has no Events, all the GO TO selections will take you to the
beginning, with the program header information summarized on the left (as Event 0) and the
Select an Event options for Event 1 on the right.
YES and NO: Yes and no appear when the Dwell Request, Auxiliary Function Request
and the Event Comments are highlighted. Choosing Yes will give you prompts for using
these options while you are programming. You may return to the Program Header
S creen at any time to choose or cancel these prompts.
PART GEO: sets up the programming as Part Geometry.
TOOL PATH: sets up the programming as Tool Path. This function is part of the
Advanced Features Option.
7.4 Auxiliary (AUX) Functions (Three-Axis CNC Models Only)
When the Auxiliary Function Option is installed and active, the ProtoTRAK SMX CNC can
control four different auxiliary functions. You can select whether to activate or
deactivate these functions at the beginning or end of each event.
If Auxiliary Functions are selected on the program header, the system will prompt for
AUX BEG and AUX END in each event.
When running programs with Auxiliary functions, the ACCESSORY hard key on the front panel
must be in the correct position. If you want the program to automatically turn the Auxiliary
functions on and off, press the ACCESSORY key until the light is on in the AUTO position.

Turns off the spindle at the end of this event. Note, the spindle automatically
turns off for each tool change – it is not necessary to program a spindle off.
Coolant/Air on and off is automatically programmed for tool changes. If you want the
air or coolant pump on while cutting the entire part, you need only program the Aux
begin in the first event and Aux end in the last event. The coolant pump or air solenoid
will turn on at the beginning of the programmed event and will turn off during tool
changes.
The Pulse Indexer function is designed to operate with a standard indexer. Programming an
Aux 3 at the end of an event will cause the ProtoTRAK SMX CNC to stop machining at the end
of the event and wait for a signal from the indexer or rotary table that it has finished its
programmed move, then it will resume machining at the next event. If you want the
ProtoTRAK SMX CNC to return the head to the Z retract position before moving to the next
event, put the Aux 3 command in a Pause event. The ProtoTRAK SMX CNC will interpret the
signal from the indexer or rotary table as a GO command and continue machining without
you having to press the GO key.
7.5 Multiple Fixtures
This function is part of the Advanced Features Option.
You may run your program using up to six fixtures plus a base. A fixture is a location on your
machine with a defined offset from your absolute 0. When you program an event to have a
fixture, it will treat the offset as if it were absolute zero shift. The programmed X, Y and Z
absolute dimensions are relative to the absolute reference for the specified fixture.
For example, say you had two vises on the table. On the first vise, you established the lower
left jaw as the absolute 0. At the same time, you measured the distance between the
absolute zero you just established and the lower left jaw of the other vise. You entered that
measurement as an offset from your base vise (the first one) and the other vise, which is
Fixture #2. Any events that you programmed using Fixture #2 would treat the lower left
corner of that second vise like the absolute 0 for the X, Y and Z dimensions in the events.
Fixture offsets are handy for combining different programs together to run at the same
time or to make multiple parts by repeating the events with different fixtures.
The fixture offsets are entered in the Set-up mode. There is a base fixture, called
fixture number one. We recommend that Event #1 in your program uses fixture
number one. It doesn’t have to; we just believe it is clearer that way.
7.5.1
The Default Fixture
In the program header screen, you entered a default fixture number (if you didn’t, it assumed
fixture #1 as the default fixture). If there are program events already in current memory
when you change the multiple fixture from NO to YES, they will all receive the default fixture
number automatically. When you change the default fixture number in the program header
screen from one fixture to another, all the events that had the previous default fixture
number will be changed to the new default fixture number.
53
XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
If there are no program events in current memory when you change the multiple fixture
feature from NO to YES, the prompt will be added to the end of every event you then
program. The default fixture number will be assumed if you press SET without
specifying a different number. If you do specify a different fixture number that fixture
number will become the assumed input for subsequent events when SET is pressed.
7.5.2
Fixtures and Running the Program
To run the program, first go to the DRO mode and set absolute 0 at the base fixture,
Fixture #1.
In the Run mode, the SHOW ABS displays the absolute position relative to the fixture in
the event being run, that is, the absolute dimension that was programmed.
7.5.3 Editing Fixtures
With the Multiple Fixtures feature turned to YES, you may edit the fixture number in the
Program Mode event by event. You may also use the Search Edit feature in the Edit
Mode to change fixture numbers.
See Section 11.4 for setting up fixture offsets.
7.6 Assumed Inputs
The ProtoTRAK SMX CNC will automatically program the following when you simply
press SET (either INC SET or ABS SET):
Tool Offset: If the first event with an offset, CENTER. If not the first event with an
offset, the same as the last event if that event was a Mill or Arc event
Feedrate: same as last event if that event was a Mill, Arc, Pocket, Frame, or Helix
Tool #: same as last event, or Tool #1 if the first event
DRILL OR BORE: Drill
# PECKS FOR DRILL: 1 peck
CONRAD: 0
You may change these assumed inputs by simply inputting the desired data when the
event is programmed.
7.7 Z Rapid Positioning
(Three-Axis CNC Models)
Between any two events the head will always move to the higher of the Z rapid of the
event just completed or the Z Rapid of the next event, unless the two events are
connective (see Section 5.9). Remember, when using part geometry programming, two
milling events are not connective unless they lie in the same plane.
54
XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
7.8 Softkeys within Events
Once a geometry (Event) such as Mill or Bolt Hole is selected, the softkeys will change.
See Figure 7.8
FIGURE 7.8 Soft keys used while programming an event
PAGE FWD: moves forward through the programmed events.
PAGE BACK: moves backwards through the programmed events.
DATA FWD: moves forward through the event inputs. Note, use the DATA FWD key
and not a SET key when you do not want to input a value.
DATA BACK: moves backwards through the event inputs.
DATA BOTTOM: puts the Highlight on the last input.
INSERT EVENT: use this to insert a new event into the program. This new event will
take the place of the one that was on the right side of the screen when you pressed the
INSERT EVENT key. That previous event, and all the events that follow, increase their
event number by one. For example, if you started with a program of four events, if you
were to press the INSERT EVENT key while Event 3 was on the right side of the screen,
the previous Event 3 would become Event 4 and the previous Event 4 would become
Event 5. If you insert a Subroutine event, the event numbers will increase by one as
when you insert another kind of event. If you insert a copy event, the event numbers
will increase by the number of events that are copied.
DELETE EVENT: this will delete the event on the right side of the screen.
7.9 Programming Events
Once you press the appropriate GO TO soft key, you will begin to define your part as a series
of Events. For the ProtoTRAK SMX CNC, an Event is a geometry, or a feature of a part.
FIGURE 7.9.1 The header screen has been completed and is on the left side. Select an event type
from the soft keys. Three-axis CNC events are shown.
55
XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
When the MORE soft key is selected, the soft keys change to:
FIGURE 7.9.2 When the More soft key is selected, these additional event types are available
for three-axis CNC models. If the Advanced Features or E-Head Option are not active,
relevant functions will be grayed out.
After an event type is selected from the soft keys, the prompts for that event will appear
on the right side of the screen. The data you need to enter to program the event will
appear in the Data Input Line. As soon as you enter one piece of data by pressing the
INC SET or ABS SET key, the next prompt will appear in the Data Input Line.
FIGUR E 7.9.3 Here, a Bolt Hole event was selected for three-axis CNC. For twoaxis, Z programming prompts do not appear. The ProtoTRAK SMX CNC is
prompting you to enter the number of holes.
7.10 Editing Data While Programming
While programming an event, all data is entered by pressing the appropriate numeric
keys and pressing INC SET or ABS SET. If you enter an incorrect number before you
press INC SET or ABS SET you may clear the number by pressing RSTR (Restore).
Then, input the correct number and press SET.
If incorrect data has been entered and SET, you may correct it as long as you are still
programming that same event. Press the DATA BACK or DATA FWD (Forward) soft
key until the incorrect prompt and data are highlighted and shown in the conversation
line. Enter the correct number and SET. The ProtoTRAK SMX CNC will not allow you to
skip past prompts (by pressing DATA FWD) which need to be entered to complete an
event except when using the A.G.E. in the Irregular Pocket or Irregular Profile event.
Previous events may be edited by pressing the BACK hard key to the left of the soft keys.
The previous event will be shifted from the left side of the screen to the right and may
be edited. The BACK key may be pressed all the way to the Program Header Screen
(the PAGE BACK softkey will work as well).

7.11 LOOK
As you program each event, it is helpful to see your part drawn. For quick graphics
while in the Program Mode, press the LOOK hard key.
This function is active at the end of each event, or whenever the conversation line is
prompting Select Event. Press the LOOK key and the ProtoTRAK SMX CNC will draw the
part. Press LOOK again, or BACK to bring back the Select Event screen. You may also
select a new view or adjust the view.
Softkeys in LOOK:
ADJUST VIEW: gives additional options for adjusting the view of the drawing. See
below.
FIT DRAW: automatically resizes the drawing to fit the entire part program on the
screen.
LIST STEP: displays the list of events on the left side of the screen and with a purple
highlight on the first event. As LIST STEP is pushed, the highlight shifts to the next
event. As this happens, that event is also highlighted in the graphics by having its color
change to purple.
START EVENT NUMBER: will prompt you to enter an event number for highlighting.
This is useful for moving quickly to a particular event in a large program.
XY: displays a view in the XY plane.
YZ: displays a view in the YZ plane.
XZ: displays a view in the XZ plane.
3D: displays an isometric view
Softkeys in Adjust view:
FIT DRAW: automatically resizes the drawing to fit the entire part program on the screen.
6: shifts drawing down.
5: shifts drawing up.
3: shifts drawing to the left.
4: shifts drawing to the right.
ZOOM IN: makes the drawing larger.
ZOOM OUT: makes the drawing smaller.
RETURN: returns you to the first LOOK screen. The adjustments you made will stay on the
screen until you press another selection that overrides those adjustments. The LIST STEP
function may be used with the adjustment unaltered.
Note: The LOOK routine does not check for programming errors. Use Tool Path in the SET
UP Mode to check movement of the tool.
7.12 Finish Cuts
The Pocket and Profile events are designed with built-in finish cut routines because they
are complete, and stand-alone pieces of geometry. Shapes machined with a series of
Mill or Arc events (either with or without A.G.E. Profile) don't have an automatic routine
for making finish cuts. There is, however, a very simple technique that can be used.
a.
Program the shape using the print dimensions, and ignore the need to leave
material for a finish cut.
b.
Using a subroutine event, Repeat all the events in "a." but call out a different tool
number.
57
XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
c.
In Set-Up Mode "lie" about the tool diameter for the tool called out in events in
"a.". Input a tool diameter equal to the actual tool diameter plus 2 times the
finish cut you wish to leave. The ProtoTRAK SMX CNC will think the tool is bigger
than it really is and, therefore, shift a little further away from the machined
shape.
d.
In Set-Up Mode input the actual diameter for the tool called in the Repeat event
"b". This will produce the final dimensioned cut.
7.13 Two Versus Three-Axis Programming for Three-Axis
CNC Models.
For mills with the Z-axis ballscrew and motor assembly installed, the ProtoTRAK SMX
CNC may be operated as either a two or three-axis CNC. Many jobs in tool rooms are
simply easier to do with a two-axis CNC. Other jobs are more complex or require a lot
of metal removal, so the extra programming and set-up of the three-axis is worth the
effort.
The ProtoTRAK SMX CNC lets you choose how much CNC you want to use on the job at
hand. See Section 4.6 for switching between two and three-axis operation.
Programming is very similar between the two.

additional prompts.
For the convenience of users who have two-axis CNC models, the programming will be
explained in two different sections. If you have a three-axis CNC model, we suggest you
skip the two-axis programming section since the programming is very similar.

7.0 Program Mode
Getting Started & Some General Information
7.1 Programming Overview
The ProtoTRAK SMX CNC makes programming easy by allowing you to program the
actual part geometry as defined by the print.
The basic strategy is to first fill in the initial program information in the Program Header
screen and then program the features of the part by selecting the soft key event types
(geometry) and then follow all instructions in the Data Input Line.
When an event is selected, all the prompts that need to be input will be shown on the
right side of the screen. The first prompt will be highlighted and also shown in the Data
Input Line. Input the dimension or data requested and press INC SET or ABS SET. For
X or Y dimension data it is very important to properly select INC SET or ABS SET. For
all other data either SET will do.
As data is being entered it will show in the Data Input Line. When SET, the data will be
transferred to the list of prompts in the right side of the screen, and the next prompt will
be shown in the Data Input Line.
When all data for an event has been entered, the entire event will be shifted to the left
side of the screen and the conversation line will ask you to select the next event.
7.2 Enter Program Mode
Press MODE, select PROGRAM soft key.
The ProtoTRAK SMX CNC will allow only one program in current memory. To write a
new program, you must first erase the one in current memory (you may want to first
store the program for use in the future). If there is already a program in current
memory, entering the Program mode will allow you to edit or add to that program.
FIGURE 7.2 The Program Mode header screen. Most selections
above relate to the Advanced Features Option. If your screen shows
only Program Name and Dwell, The Advanced Features Option is not
active.

XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
7.3 Program Header Screen
The first screen you see when you enter the Program Mode is the Program Header
Screen. The Program Header Screen gives you options that apply to the entire
program. The softkey selections allow you to ente r the program at any point.
The program name and general programming options you choose in the Program
Header Screen will be summarized in the program as "Event 0".
7.3.1
Program Name
Programs written on the ProtoTRAK SMX CNC are usually named for the part that is to
be machined. When programs (or files) are named using the ProtoTRAK SMX CNC, the
name can be up to 20 characters long. Programs imported into the ProtoTRAK SMX
CNC may be longer. While 20 characters are allowed, the entire program name may
not be shown in the status line or the program header screen.
FIGURE 7.3 Pressing the Help hard key when the Program Name is highlighted calls up alpha
keys
Program names can include numbers, letters, spaces and other characte rs. When the
Program name prompt is highlighted, the Data Input Line will show "Program Name:".
At this point you may:
•
•
•
Press number keys.
Press Help to access alpha keys and special characters in the ProtoTRAK SMX
CNC.
Use a keyboard plugged into the ProtoTRAK SMX CNC to name the program.
To use the alpha keys and special characters on the ProtoTRAK SMX CNC:
Use the Clear softkey to erase the entire line; the Backspace softkey to erase the last
character or number.
•
Use the arrow softkeys to move around the table.

•
•
•
Once the character you want is highlighted, use the Enter softkey to load the
character into the program name.
Use the blank space on the lower right of the table to insert a space into the
program name.
Once you finish entering the letters and special characters, press the End softkey.
This tells the ProtoTRAK SMX CNC that you are finished with the alpha table.
Numbers may still be added to the program name.
When you are finished with the program name, press SET to enter it into the current memory.
Note: It is not necessary to enter a part number. If none is entered and a GO TO soft key is
pushed, the system will assume a part number 0.
7.3.2
General Program Options
Use the DATA FWD softkey to select general programming options. See Section 3.1.2
for more information about the Advanced Features Option.
Scale : Allows a scale factor between .1 and 10. An input of 5 means the part will be 5
times as big as the programmed dimensions. A value of 1.0000 is assumed if nothing is
input. This function is part of the Advanced Features Option.
Dwell Request: For three-axis CNC machining only. Allows you to input a dwell at the
bottom of a drill, bolt hole or bore cycle for events you select. Select the appropriate
YES or NO soft key. If you select YES you will be prompted to input a dwell time in
seconds from .1 to 99.9 when appropriate to the event being programmed.
Auxiliary Function Request: Asks if you wish to activate any of the optional auxiliary
functions (see Section 7.4) at any time during the program. Select the appropriate YES
or NO soft key. If you select YES you will be prompted to input the type and sequencing
of the auxiliary functions during event programming. Auxiliary Functions are optional for
three-axis CNC models only.
Event Comments: If you select "Yes" for event comments, you will have the
opportunity to insert a comment in each event. For Irregular Pocket and Irregular
Profile events, you will be able to enter a comment at the header event, but not for each
A.G.E. Turn and A.G.E. Arc event. This function is part of the Advanced Features
Option.
Comments appear in the RUN mode on the Data Input Line as the event begins to run.
Comments may be composed of letters, numbers and some symbols and may be up to
20 characters.
While programming the event with the Event Comments set to Yes, when the highlight is
on the Event Comments prompt, you may enter a comment using the same methods
used to enter a program name, as described above.
Multiple Fixtures: Asks you if you wish to turn on the multiple fixtures offset.
Answering Yes will cause a prompt to appear at each event asking which fixture the
event was referenced from. If you select Yes, the Data Input Line will ask you to enter a
fixture default number from one to six. The fixture default number is the fixture that will
be applied to all the events in current memory when Multiple Fixtures is turned on or
when a new event is programmed without another event being specified. Enter the
default fixture, or leave the number unchanged, and press SET. Multiple Fixtures are
explained more fully in Section 7.5. This function is part of the Advanced Features
Option.
Dimension Definition: The ProtoTRAK SMX CNC gives you a choice in programming either
tool path or geometry. Part Geometry programming allows you to define the geometry you
want your part to have and then the CNC does the difficult job of calculating tool path for
you automatically. This is a great benefit for most parts most of the time because it means
that the CNC is doing the hard work of determining tool position.

One restriction to part geometry programming is that for events to be connective, they
must lay on the same plane (see Section 5.3 for a definition of planes). For this reason,
the ProtoTRAK SMX CNC gives you the option of entering your own tool path. If you
wish to program the part by defining tool path yourself, you may choose the TOOL PATH
softkey. Otherwise, Part Geometry programming is assumed. Tool Path operates under
the same rules as standard RS274.
A program must be entirely written in Part Geometry or Tool Path programming, you
cannot combine the two methods in one program. Tool Path programming is part of the
Advanced Features Option.
7.3.3
Program Header Softkeys
The following softkeys are encountered in the Program Header Screen. The first five
listed below are always there. The last four appear when relevant to the general
programming option.
DATA FWD: moves the highlight forward through the programming options without
setting an input into the program.
DATA BACK: moves the highlight backward through the programming options without
setting an input into the program.
GO TO BEGIN: puts the Program Header on the left side of the screen and the first event
on the right side.
GO TO END: puts the last programmed event on the left side of the screen and the next
event to be programmed on the right side.
GO TO #: enter the event number you wish to go to and then press SET. Puts the
requested event number on the right side of the screen and the previous event number
on the left.
Note: for a new program that has no Events, all the GO TO selections will take you to the
beginning, with the program header information summarized on the left (as Event 0) and the
Select an Event options for Event 1 on the right.
YES and NO: Yes and no appear when the Dwell Request, Auxiliary Function Request
and the Event Comments are highlighted. Choosing Yes will give you prompts for using
these options while you are programming. You may return to the Program Header
S creen at any time to choose or cancel these prompts.
PART GEO: sets up the programming as Part Geometry.
TOOL PATH: sets up the programming as Tool Path. This function is part of the
Advanced Features Option.
7.4 Auxiliary (AUX) Functions (Three-Axis CNC Models Only)
When the Auxiliary Function Option is installed and active, the ProtoTRAK SMX CNC can
control four different auxiliary functions. You can select whether to activate or
deactivate these functions at the beginning or end of each event.
If Auxiliary Functions are selected on the program header, the system will prompt for
AUX BEG and AUX END in each event.
When running programs with Auxiliary functions, the ACCESSORY hard key on the front panel
must be in the correct position. If you want the program to automatically turn the Auxiliary
functions on and off, press the ACCESSORY key until the light is on in the AUTO position.

Coolant/Air on and off is automatically programmed for tool changes. If you want the
air or coolant pump on while cutting the entire part, you need only program the Aux
begin in the first event and Aux end in the last event. The coolant pump or air solenoid
will turn on at the beginning of the programmed event and will turn off during tool
changes.
The Pulse Indexer function is designed to operate with a standard indexer. Programming an
Aux 3 at the end of an event will cause the ProtoTRAK SMX CNC to stop machining at the end
of the event and wait for a signal from the indexer or rotary table that it has finished its
programmed move, then it will resume machining at the next event. If you want the
ProtoTRAK SMX CNC to return the head to the Z retract position before moving to the next
event, put the Aux 3 command in a Pause event. The ProtoTRAK SMX CNC will interpret the
signal from the indexer or rotary table as a GO command and continue machining without
you having to press the GO key.
7.5 Multiple Fixtures
This function is part of the Advanced Features Option.
You may run your program using up to six fixtures plus a base. A fixture is a location on your
machine with a defined offset from your absolute 0. When you program an event to have a
fixture, it will treat the offset as if it were absolute zero shift. The programmed X, Y and Z
absolute dimensions are relative to the absolute reference for the specified fixture.
For example, say you had two vises on the table. On the first vise, you established the lower
left jaw as the absolute 0. At the same time, you measured the distance between the
absolute zero you just established and the lower left jaw of the other vise. You entered that
measurement as an offset from your base vise (the first one) and the other vise, which is
Fixture #2. Any events that you programmed using Fixture #2 would treat the lower left
corner of that second vise like the absolute 0 for the X, Y and Z dimensions in the events.
Fixture offsets are handy for combining different programs together to run at the same
time or to make multiple parts by repeating the events with different fixtures.
The fixture offsets are entered in the Set-up mode. There is a base fixture, called
fixture number one. We recommend that Event #1 in your program uses fixture
number one. It doesn’t have to; we just believe it is clearer that way.
7.5.1
The Default Fixture
In the program header screen, you entered a default fixture number (if you didn’t, it assumed
fixture #1 as the default fixture). If there are program events already in current memory
when you change the multiple fixture from NO to YES, they will all receive the default fixture
number automatically. When you change the default fixture number in the program header
screen from one fixture to another, all the events that had the previous default fixture
number will be changed to the new default fixture number.

XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
If there are no program events in current memory when you change the multiple fixture
feature from NO to YES, the prompt will be added to the end of every event you then
program. The default fixture number will be assumed if you press SET without
specifying a different number. If you do specify a different fixture number that fixture
number will become the assumed input for subsequent events when SET is pressed.
7.5.2
Fixtures and Running the Program
To run the program, first go to the DRO mode and set absolute 0 at the base fixture,
Fixture #1.
In the Run mode, the SHOW ABS displays the absolute position relative to the fixture in
the event being run, that is, the absolute dimension that was programmed.
7.5.3 Editing Fixtures
With the Multiple Fixtures feature turned to YES, you may edit the fixture number in the
Program Mode event by event. You may also use the Search Edit feature in the Edit
Mode to change fixture numbers.
See Section 11.4 for setting up fixture offsets.
7.6 Assumed Inputs
The ProtoTRAK SMX CNC will automatically program the following when you simply
press SET (either INC SET or ABS SET):
Tool Offset: If the first event with an offset, CENTER. If not the first event with an
offset, the same as the last event if that event was a Mill or Arc event
Feedrate: same as last event if that event was a Mill, Arc, Pocket, Frame, or Helix
Tool #: same as last event, or Tool #1 if the first event
DRILL OR BORE: Drill
# PECKS FOR DRILL: 1 peck
CONRAD: 0
You may change these assumed inputs by simply inputting the desired data when the
event is programmed.
7.7 Z Rapid Positioning
(Three-Axis CNC Models)
Between any two events the head will always move to the higher of the Z rapid of the
event just completed or the Z Rapid of the next event, unless the two events are
connective (see Section 5.9). Remember, when using part geometry programming, two
milling events are not connective unless they lie in the same plane.

7.8 Softkeys within Events
Once a geometry (Event) such as Mill or Bolt Hole is selected, the softkeys will change.
See Figure 7.8
FIGURE 7.8 Soft keys used while programming an event
PAGE FWD: moves forward through the programmed events.
PAGE BACK: moves backwards through the programmed events.
DATA FWD: moves forward through the event inputs. Note, use the DATA FWD key
and not a SET key when you do not want to input a value.
DATA BACK: moves backwards through the event inputs.
DATA BOTTOM: puts the Highlight on the last input.
INSERT EVENT: use this to insert a new event into the program. This new event will
take the place of the one that was on the right side of the screen when you pressed the
INSERT EVENT key. That previous event, and all the events that follow, increase their
event number by one. For example, if you started with a program of four events, if you
were to press the INSERT EVENT key while Event 3 was on the right side of the screen,
the previous Event 3 would become Event 4 and the previous Event 4 would become
Event 5. If you insert a Subroutine event, the event numbers will increase by one as
when you insert another kind of event. If you insert a copy event, the event numbers
will increase by the number of events that are copied.
DELETE EVENT: this will delete the event on the right side of the screen.
7.9 Programming Events
Once you press the appropriate GO TO soft key, you will begin to define your part as a series
of Events. For the ProtoTRAK SMX CNC, an Event is a geometry, or a feature of a part.
FIGURE 7.9.1 The header screen has been completed and is on the left side. Select an event type
from the soft keys. Three-axis CNC events are shown.

When the MORE soft key is selected, the soft keys change to:
FIGURE 7.9.2 When the More soft key is selected, these additional event types are available
for three-axis CNC models. If the Advanced Features or E-Head Option are not active,
relevant functions will be grayed out.
After an event type is selected from the soft keys, the prompts for that event will appear
on the right side of the screen. The data you need to enter to program the event will
appear in the Data Input Line. As soon as you enter one piece of data by pressing the
INC SET or ABS SET key, the next prompt will appear in the Data Input Line.
FIGUR E 7.9.3 Here, a Bolt Hole event was selected for three-axis CNC. For twoaxis, Z programming prompts do not appear. The ProtoTRAK SMX CNC is
prompting you to enter the number of holes.
7.10 Editing Data While Programming
While programming an event, all data is entered by pressing the appropriate numeric
keys and pressing INC SET or ABS SET. If you enter an incorrect number before you
press INC SET or ABS SET you may clear the number by pressing RSTR (Restore).
Then, input the correct number and press SET.
If incorrect data has been entered and SET, you may correct it as long as you are still
programming that same event. Press the DATA BACK or DATA FWD (Forward) soft
key until the incorrect prompt and data are highlighted and shown in the conversation
line. Enter the correct number and SET. The ProtoTRAK SMX CNC will not allow you to
skip past prompts (by pressing DATA FWD) which need to be entered to complete an
event except when using the A.G.E. in the Irregular Pocket or Irregular Profile event.
Previous events may be edited by pressing the BACK hard key to the left of the soft keys.
The previous event will be shifted from the left side of the screen to the right and may
be edited. The BACK key may be pressed all the way to the Program Header Screen
(the PAGE BACK softkey will work as well).

screen.
LIST STEP: displays the list of events on the left side of the screen and with a purple
highlight on the first event. As LIST STEP is pushed, the highlight shifts to the next
event. As this happens, that event is also highlighted in the graphics by having its color
change to purple.
START EVENT NUMBER: will prompt you to enter an event number for highlighting.
This is useful for moving quickly to a particular event in a large program.
XY: displays a view in the XY plane.
YZ: displays a view in the YZ plane.

RETURN: returns you to the first LOOK screen. The adjustments you made will stay on the
screen until you press another selection that overrides those adjustments. The LIST STEP
function may be used with the adjustment unaltered.
Note: The LOOK routine does not check for programming errors. Use Tool Path in the SET
UP Mode to check movement of the tool.
7.12 Finish Cuts
The Pocket and Profile events are designed with built-in finish cut routines because they
are complete, and stand-alone pieces of geometry. Shapes machined with a series of
Mill or Arc events (either with or without A.G.E. Profile) don't have an automatic routine
for making finish cuts. There is, however, a very simple technique that can be used.
a.
Program the shape using the print dimensions, and ignore the need to leave
material for a finish cut.
b.
Using a subroutine event, Repeat all the events in "a." but call out a different tool
number.
57
XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
c.
In Set-Up Mode "lie" about the tool diameter for the tool called out in events in
"a.". Input a tool diameter equal to the actual tool diameter plus 2 times the
finish cut you wish to leave. The ProtoTRAK SMX CNC will think the tool is bigger
than it really is and, therefore, shift a little further away from the machined
shape.
d.
In Set-Up Mode input the actual diameter for the tool called in the Repeat event
"b". This will produce the final dimensioned cut.
7.13 Two Versus Three-Axis Programming for Three-Axis
CNC Models.
For mills with the Z-axis ballscrew and motor assembly installed, the ProtoTRAK SMX
CNC may be operated as either a two or three-axis CNC. Many jobs in tool rooms are
simply easier to do with a two-axis CNC. Other jobs are more complex or require a lot
of metal removal, so the extra programming and set-up of the three-axis is worth the
effort.
The ProtoTRAK SMX CNC lets you choose how much CNC you want to use on the job at
hand. See Section 4.6 for switching between two and three-axis operation.
Programming is very similar between the two.

8.0 Two-Axis Program Events
This section describes the events and prompts you encounter when programming your ProtoTRAK
SMX as a two-axis CNC. If you have a three-axis XYZ Turret Mill you may want to skip this section.
Events are fully defined pieces of geometry. By programming events, you tell the ProtoTRAK
SMX CNC what geometry you want to end up with; it figures the tool path for you from your
answers to the prompts and the tool information you give it in the Set-Up Mode.
8.1 POSN DRILL:
This event type positions the table and quill at a specified position. The positioning is always
at rapid speed (modified by feedrate override) and in the most direct path possible from the
previous location. You would use this event type to program a hole for drilling. In program
run, the CNC will move to the dimension you program and will wait for you to press GO
before moving to the next event. You may also use this event type to position the table for
some other purpose, such as to avoid a clamp or to move off the workpiece for a tool
change.
To program a Position event press the POSN DRILL soft key.
Prompts for the Position event:
X END is the X dimension to the position
Y END is the Y dimension to the position
Tool # is the tool number you assign. SET will use the tool number of the previous event.
8.2 BOLT HOLE Events
This event allows you to program a bolt hole pattern without needing to compute and
program the position of each hole.
Prompts for the Bolt Hole event:
# Holes: is the number of holes in the bolt hole pattern
X Center: is the X dimension to the center of the hole pattern
Y Center: is the Y dimension to the center of the hole pattern
Radius: is the radius of the hole pattern from the center to the center of the holes
Angle: is the angle from the positive X axes (that is, 3 o'clock) to any hole; positive angle is
measured counterclockwise from 0.000 to 359.999 degrees, negative angles measured
clockwise.
Tool #: is the tool number you assign
8.3 MILL Events
This event allows you to mill in a straight line from any one XYZ point to another, including at
a diagonal in space. It may be programmed with a CONRAD if it is connective with the next
event.
Prompts for the Mill event:
X Begin: is the X dimension to the beginning of the mill cut
Y Begin: is the Y dimension to the beginning of the mill cut
X End: is the X dimension to the end of the mill cut; incremental is X Begin
Y End: is the Y dimension to the end of the mill cut; incremental is Y Begin
Conrad: is the dimension of a tangential radius to the next event (that must lie in
the same plane for part geometry programming).
61
XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
Tool Offset: is the selection of the tool offset to right (input 1), offset to left (input
2), or tool center--no offset (input 0) relative to the programmed edge and direction
of tool cutter movement and as projected in the XY plane.
Feedrate: is the milling feedrate from Begin to End in in/min from .1 to 100, or
mm/min from 5 to 2540 (up to 3800 for model SLV)

Continue: input 1 for Yes if you want to mill continuously from this line to the next
event, input 2 for No if you want the ProtoTRAK SMX to stop at the end of the event.
8.4 ARC Events
This event allows you to mill with circular contouring any arc (fraction of a circle).
In ARC events when X Center and Y Center are programmed incrementally, they are
referenced from X End and Y End respectively. An ARC event may be programmed
with a CONRAD if it is connective with the next event.
Prompts for the Arc event:
X Begin: is t he X dimension to the beginning of the arc cut
Y Begin: is the Y dimension to the beginning of the arc cut
X End: is the X dimension to the end of the arc cut; incremental is from X Begin
Y End: is the Y dimension to the end of the arc cut; incremental is from Y Begin
X Center: is the X dimension to the center of the arc; incremental is from X End
Y Center: is the Y dimension to the center of the arc; incremental is from Y End
Conrad: is the dimension of a tangential radius to the next event
Directio n: is the clockwise (input 1), or counterclockwise (input 2) direction of the
arc

Continue: input 1 for Yes if you want to mill continuously from this line to the next
event, input 2 for No if you want the ProtoTRAK SMX to stop at the end of the event.
8.5 POCKET Event
This event selection gives you a choice between circle pocket, rectangular pocket and irregular
pocket.
Pockets include machining the circumference, as well as all the material inside the circumference
of the programmed shape. If a finished cut is programmed, it will be made at the completion of
the final pass. The cutter will arc in and arc out of the finish cut and position itself the finish cut
dimension away from the part before moving the tool out of the part.
The factory setting for tool stepover while machining a pocket is 70%. This may be
changed. When you first enter the pocket event, the blue ? will appear next to the help
key. Pressing Help will give you the choice of entering a new tool stepover percentage.
The value you enter here will remain the same until you change it again.

8.5.3
Irregular Pocket (Advanced Features Option)
Press the IRREG PCKT soft key if you wish to mill a pocket other than a rectangle or
circle. The Irregular Pocket event gives you the powerful Auto Geometry Engine to
define a shape made up of straight lines (Mills) and arcs.
The first screen in an irregular pocket event will define the beginning point and some

Fin Feedrate: is the finish cut milling feedrate in in/min from .1 to 100, or mm/min
from 5 to 2540 (up to 3800 for model SLV)
Tool #: is the tool number you assign
When the initial screen is complete, you will define the perimeter of the pocket with a
series of A.G.E. Mills and A.G.E. Arcs. Programming with the Auto Geometry Engine
is explained in Section 10.0.
No islands may exist in an irregular pocket.
8.5.4
Tool Path in Pocket Events
In Program Run, the ProtoTRAK SMX will first direct the cutter along a path to rough
out all the material inside of the perimeter, and then will do a rough cut along the
inside of the perimeter which leaves the amount of material programmed in the FIN
CUT prompt. This will be followed by a finish pass (if FIN CUT was not zero) along
the inside of the perimeter at the Finish Feedrate.
Whether the cuts to clear the interior material of the irregular pocket are along the X
or Y -axis depends on if there are hidden areas of the pocket. The ProtoTRAK SMX
CNC always looks to cut along the X -axis first. If there are areas that are hidden to
the X-axis, it will machine along the Y-axis. If there are hidden areas that cannot be
machined continuously in the X or Y -axis, the pocket will be machined in two or more
steps. When a step is completed, the ProtoTRAK SMX will prompt "CHECK Z" at
which time you should raise your quill out of the pocket. Press GO and the tool will
move at rapid to the beginning of the next step and then there will be a prompt for
you to "SET Z" for you to position the tool for the depth you want.
In the Set Up Mode, you may check your tool path for hidden areas. The yellow X's
show points where you will receive a prompt to move the quill. The red dashed lines
show the rapid moves.
8.5.5
Conrad in Pocket Events
A conrad may be added to the last event of an Irregular Pocket. The conrad will be inserted
between the end of the last event and the beginning of the next event.
8.6 Islands (Advanced Features Option)
Islands programming is available as part of the Advanced Features Option. See
Section 3.1.2.
Within the Pocket event choices, you may also select a circular, rectangular or
irregular island. An island is a shape that is left standing when the surrounding
material is removed. The ProtoTRAK give s you the ability to machine almost any
shape as an island within a rectangular pocket. Both the shape of the island and the
dimension of the surrounding pocket are defined within the island event.
The tool path for machining the island event is that the tool will machine the perimeter of the
island, offset by the island finish cut. Then the tool will machine the material in the pocket in a
spiral path, moving away from the island in the programmed clockwise or counterclockwise
direction. It will continue this outward spiral motion until it encounters the programmed
rectangular perimeter (or pocket). It will then follow the perimeter, offset by the pocket finish
cut.

Feedrate: is the milling feedrate in in/min from .1 to 100, or mm/min from 5 to 2540 (up
to 3800 for model SLV).
Fin Cut: is the width of the finish cut. If 0 is input there will be no finish cut.
Fin Feedrate: is the finish cut milling feedrate in in/min from .1 to 100, or mm/min
from 5 to 2540 (up to 3800 for model SLV).
Tool #: is the tool number you assign.
When the initial Irregular Profile screen is complete, the rest of the profile is
programmed using A.G.E. Mill and A.G.E. Arc events. Programming with the Auto
Geometry Engine is explained in Section 10.0. Irregular Profile and Auto Geometry
Engine programming is part of the Advanced Features Option.
8.8 Engrave Event (Advanced Features Option)
The Engrave Event allows you to machine numbers, letters and special characters as
part of a part program. See figure 8.8 below for the letters and special characters
that are available in the Engrave Event.
When programming with the Engrave Event, the ProtoTRAK will construct a box to contain
the text you define. This box is oriented along the X axis like the text in this sentence,
and you may program up to 40 characters per event (although you will only be able to see
20 characters on the prompts screen). To machine text in a direction other than the X
axis, simply use multiple Engrave Events and place the lower left corner of the box
wherever you would like. The numbers and letters you program will always have a
standard orientation (like the letters on this page) – you cannot program tilted or inverted
letters with the Engrave Event. The letters are of the font shown in the figure and all
capitals.
Prompts for the Engrave Event
First, define the lower left corner of the box that will contain your text:
X BEGIN: The X coordinate of where you want your text to begin.
Y BEGIN: The Y coordinate of where you want your text to begin.
HEIGHT: The height of your text. Each character varies in width; the set height of the
character will change the width in order to keep the overall size of the character
proportional.
TEXT: The text to be milled. When you get to this prompt, the Alpha keys will
automatically pop up to allow you to enter the text. Once you have finished entering text,
you must press End (F8) and then any of the SET keys to successfully enter your text into
the event. The alpha keys will appear automatically if the text field is blank. If you have
already entered text but wish to make a change, you will see a blue question mark appear
on the lower left corner of the screen when you scroll to this field, press the Help button
and the alpha keys will appear.
FEEDRATE: The feedrate of XYZ along the path of the text.
Tool #: is the tool number you assign.

FIGURE 8.8 The above figureshows the text and special characters available for the
Engrave event. Notice the field that is labeled “Text Length”. This field will display the total
length of your programmed text and will update as you enter each character.
8.9 Subroutine Events
The Subroutine Events are used for manipulating previously programmed geometry
within the XY plane.
The Subroutine Event is divided into three options: Repeat, Mirror, and Rotate.
Repeat and Rotate may be connective. As long as the rules of connectivity are satisfied (see
Section 5.9), the ProtoTRAK SMX CNC will continue milling between preceding and subsequent
events.
REPEAT allows you to repeat an event or a grou p of events up to 99 times with an offset in X
and/or Y. This can be useful for drilling a series of evenly spaced holes, duplicating some
machined shapes, or even repeating an entire program with an offset for a second fixture.
Repeat events may be "nested." That is, you can repeat a repeat event, of a repeat event, of
some programmed event(s). One new tool number may be assigned for each Repeat Event.
MIRROR (Advanced Features Option) is
used for parts that have symmetrical patterns
or mirror image patterns. In addition to
specifying the events to be repeated, you must
also indicate the axis or axes (X or Y or XY are
allowed) that the reflection is mirrored across.
In addition, you must specify the offset from
absolute zero to the line of reflection. You may
not mirror another mirror event, or mirror a
rotate event. Consider the figure:
FIGURE 8.9.1 Holes 1-4 are mirrored across the Y
axis to 5-8, respectively, about a line X OFFSET from
X=absolute 0
ROTATE is used for polar rotation of parts that have a rotational symmetry around
some point in the XY plane. In addition to specifying the events to be repeated, you
must also indicate the absolute X and Y position of the center of rotation, the angle
of rotation (measured counterclockwise as positive; and clockwise as negative), and
the number of times the specified events are to be rotated and repeated. You may
not rotate another rotate event, or rotate a mirror event. Consider the figure below:

dimensions. A is rotated 3 times to produce sha pe B, C, and D
Press the SUBROUTINE (SUB) soft key to call up the Repeat, Mirror, and Rotate options.
8.9.1
Repeat
Press the REPEAT soft key.
Where:
First Event #: is the event number of the first event to be repeated.
Last Event #: is the event numbe r of the last event to be repeated; if only one
event is to be repeated, the Last Event # is the same as the First Event #.
X Offset: is the incremental X offset from event to be repeated.
Y Offset: is the incremental Y offset from event to be repeated.
# Repeats: is the number of times events are to be repeated up to 99.
% Feed : the percentage of the feeds programmed in the repeated events. 100% is
assumed .
Tool #: is the tool number you assign.
8.9.2
Mirror
Press the M IRROR soft key.
First Event #: is the event number of the first event to be mirrored.
Last Event #: is the event number of the last event to be mirrored; if only one
event is to be mirrored, the last event is the same as the first.
Cutting Order: input 1 to cut from the lowest mirrored event to the highest (forward) and
2 to machine from the highest mirrored event to the lowest (backward). This way you can
keep all the machine motion in a consistent direction as it moves from the original shape to
the mirrored shape and keep all cuttin g either climb or conventional.
Mirror Axis: is the selection of the axis or axes to be mirrored (input X or Y or XY,
SET).

X Offset: is the distance from Y absolute 0 to the Y -axis line of reflection.
Y Offset: is the distance from X absolute 0 to the X-axis line of reflection.
8.9.3
Rotate
Press the ROTATE soft key.
First Event #: is the event number of the first event to be rotated.

is to be rotated, the last event is the same as the first.
X Center: is the X absolute position of the center of rotation.
Y Center: is the Y absolute position of the center of rotation.
Angle: is the angle of rotation of the repeated events (positive is counterclockwise;
negative is clockwise).
# Repeats: is the number of times events are to be rotated up to 99.
8.10 COPY Events (Advanced Features Option)
Copy Events are programmed exactly like Subroutine Events. The only difference is
that in Copy the events are rewritten into subsequent events. If, for example, in
Event 11 you Copy Repeated Events 6, 7, 8, 9, 10 with 2 repeats, Events 6-10 would
be copied with the input offsets into Events 11 -15, and recopied into 16 -20.
Copy Events may be Repeat, Mirror, or Rotate.
Copy is very useful. With copy you can:
•
Edit the events that are being repeated, mirrored or rotated without changing
the original events.
•
Connect so that the quill will not move up to the Z Rapid position, and back
down unnecessarily. However, to be connective, you m ust be certain that the X,
Y, Z begin of the first event, once offset or rotated, coincides with the X, Y, Z
end of the last event.
•
Program an event parallel to X or Y (where the geometry is the easiest to
describe), rotate it to the desired position, and then delete the original.
•
Use the Clipboard to paste previously stored events from another program into the
current program. After you press the Clipboard key, you will enter the offset from
the previous program's absolute zero to the current program's ab solute zero (see
figure below). For information about putting events into the clipboard, see
Section 11.4.
Figure 8.10 In the above example, the offset that puts the group of holes in the
desired location is X=-1.50 and Y=-1.00.

8.11 Finishing Teach Events
Teach events are either POSN/DRILL or MILL events that are originated in the DRO
Mode (see Section 6.6).
The Teach events that are started in the DRO Mode must be finished in the Program
Mode before running. Teach events are of these different types:
TEACH POSN/DRILL - See Section 8.1 for a description of Position/Drill event
prompts.
TEACH MILL - a straight line that specifies the beginning and the end. When
TEACH MILL events are defined using the CONT MILL softkey, the prompts for
information that cannot change will be suppressed. See Section 8.3 for a description
of Mill event prompts.
When a Teach event is unfinished, the words NOT OK will appear next to the event
type. Once the prompts are completed, the words NOT OK and Teach will disappear.
The event will become a normal POSN/DRILL or MILL event.

9.0 Three-Axis Program Events
This section describes the program events and prompts that are available in three -axis
programming. If your ProtoTRAK SMX CNC is configured for two-axis programming only, you
should skip this section.
Events are fully defined pieces of geometry. By programming events, you tell the ProtoTRAK
SMX CNC what geometry you want to end up with; it figures the tool path for you from your
answers to the prompts and the tool information you give it in the Set-Up Mode.
9.1 POSN: Position Events
This event type positions the table and quill at a specified position. The positioning is
always at rapid speed (modified by feedrate override) and in the most direct path
possible from the previous location. The most common use of the position event is to
move the tool around an obstacle such as a clamp. For this reason, Z and X - Y
motion will not occur simultaneously. First, the Z (head) will move to the higher of
the Z rapid position of the current and next event, then the X (table) and Y (saddle)
will move at to the programmed position.
To program a Position event press the POSN soft key.
Prompts for the Position event:
X END is the X dimension to the position
Y END is the Y dimension to the position
Z Rapid is the Z dimension to the position
RPM is the spindle RPM for the event. INC SET will use the RPM of the previous
event. RPM programming is available only if the Programmable Electronic Head
Option is active.
Tool # is the tool number you assign. SET will use the tool number of the previous event.
9.2 DRILL Events
This event positions the table to the specified X and Y position, moves the HEAD at
rapid to the Z RAPID location, feeds the quill to the Z END location, and rapids back
to Z RAPID for drill, and feeds back for bore.
Press the DRILL soft key.
Prompts for the drill event:
Drill=1, Bore=2: selects whether the hole is to be drilled or bored.
X: is the X dimension to the hole.
Y: is the Y dimension to the hole.
Z Rapid : is the Z dimension to transition from rapid to feed.
Z End : is the bottom of the hole.
# PECKS: is the number of tool withdrawal cycles. Each cycle drills and then
retracts to the Z rapid position. The factory setting is for each peck to be
successively smaller, taking the largest cuts at the beginning and the smallest at the
end (Variable). You may change this to equal pecks. To do this, press the HELP key
when the highlight is on this prompt. This will take you to a screen where you may
choose to have the same amount of material taken per peck (Fixed). You can also
choose Chip Break, where the tool will perform fixed pecks, but only rapid out about
0.5mm after each peck, instead of going back to the Z rapid position after every
peck. This new setting will remain until you change it again.
73

measured counterclockwise from 0.000 to 359.999 degrees, negative angles measured
clockwise.
Pitch: is the pitch of the tap that is used if the Tap option is chosen. Tap is available only if
the Programmable Electronic Head Option is active.
# PECKS: is the number of tool withdrawal cycles. Each cycle drills and then
retracts to the Z rapid position. The factory setting is for each peck to be
successively smaller, taking the largest cuts at the beginning and the smallest at the
end (Variable). You may change this to equal pecks. To do this, press the HELP key
when the highlight is on this prompt. This will take you to a screen where you may
choose to have the same amount of material taken per peck (Fixed). You can also
choose Chip Break, where the tool will perform fixed pecks, but only rapid out about
0.5mm after each peck, instead of going back to the Z rapid position after every
peck. This new setting will remain until you change it again.
RPM: is the spindle RPM for the event. INC SET will use the RPM of the previous
event. RPM programming is available only if the Programmable Electronic Head
Option is active.

Continue: Yes or no. This prompt appears when the Advanced Features Option is
not active in order to program a continuous tool path without stops and eliminate
repetitive prompts in the next event. If the Advanced Features Option is active, use
the Profile event to accomplish the same thing.
9.5 ARC Events
This event allows you to mill with circular contouring any arc (fraction of a circle) that
lies in the XY plane or a vertical plane (see Section 5.3). Vertical plane arcs are also
limited to those that are entirely concave or convex (in other words, if you think of
the arc lying on the surface of the earth, then it can't cross the equator).
In ARC events when X Center, Y Center, and Z Center are programmed
incrementally, they are referenced from X End, Y End, and Z End respectively. An
ARC event may be programmed with a CONRA D if it is connective with the next event
(this next event must lie in the same plane as the Arc event).
Note: When an arc is a 180 o arc, there are several paths that all have the same beginning,
ending, and center locations. To illustrate, Imagine that if you were on the earth's equator
and you wanted to get to the other side of the earth you could go clockwise or
counterclockwise around the equator, or you could go up over the north pole, or down under
the south pole. The ProtoTRAK SMX CNC will automatically assume that all 180 o arcs that
have the same beginning, ending and center dimensions for Z, lie in the XY plane. If you want
a 180o arc in a vertical plane, you must program two 90o arcs or some equivalent.
Prompts for the Arc event:
X Begin: is t he X dimension to the beginning of the arc cut.
Y Begin: is the Y dimension to the beginning of the arc cut.
Z Rapid : is the Z dimension to transition from rapid to feed.

Continue: Yes or no. This prompt appears when the Advanced Features Option is
not active in order to program a continuous tool path without stops and eliminate
repetitive prompts in the next event. If the Advanced Features Option is active, use
the Profile event to accomplish the same thing.
9.6 POCKET Event
This event selection gives you a choice between, circle pocket, rectangular pocket
and irregular pocket within the XY plane.
Pockets include machining the circumference, as well as all the material inside the
circum ference of the programmed shape. If a finished cut is programmed, it will be
made at the completion of the final pass. The cutter will arc in and arc out of the
finish cut and position itself the finish cut dimension away from the part before
moving the tool out of the part.
The factory setting for tool stepover while machining a pocket is 70%. This may be
changed. When you first enter the pocket event, the blue ? will appear next to the
help key. Pressing Help will give you the choice of entering a new tool stepover
percentage. The value you enter here will remain the same until you change it
again.

When the initial screen is complete, you will define the perimeter of the pocket with a
series of A.G.E. Mills and A.G.E. Arcs. Programming with the Auto Geometry Engine
is explained in Section 9.0.
No islands may exist in an irregular pocket.
9.6.4
Tool Path in Pocket Events
In Program Run, the pocket path will be either the plunge or zigzag cuts to Z depth
along either the X or Y, followed by the required number of cuts to clear out the
interior material, and then the rough cut along the inside of the perimeter. This will
be repeated for each pass and then followed by a finish pass (if FIN CUT was not
zero) along the inside of the perimeter at the Finish Feedrate and final depth. If a
bottom finish cut was programmed, it will be machined before the perimeter finish
cut.
Whether the cuts to clear the interior material of the irregular pocket are along the X
or Y -axis depends on if there are hidden areas of the pocket. The ProtoTRAK SMX
CNC always looks to cut along the X -axis first. If there are areas that are hidden to
the X-axis, it will machine along the Y-axis. If there are hidden areas that cannot be
machined continuously in the X or Y -axis, the tool will return to Z retract and then
reposition to machine the hidden area.
9.6.5
Zigzag Z Depth Cuts
In programming pocket events, you have a choice to program the cuts to Z depth
either as a plunge or a zigzag ramp. For rectangular and circular pockets, the tool
will start in the center of the pocket. For irregular pockets, since there is no center
defined, the tool will start in the lower left corner of the pocket. The direction of the
ramp will be the same as the initial direction in either X or Y, depending on how the
pocket is to be cut.
The tool will zigzag back and forth along the X or Y over a length of one tool radius
while at the same time moving in the Z direction. When it travels one tool radius
along this direction, it will have traveled a distance of ten percent of the tool
diameter along the Z. This works out to roughly ramping into the part at an angle of
11 degrees.
In order to use a zigzag ramp, the X or Y move must be larger than the diameter of
the tool plus the radius of the tool, minus the finish cut of the pocket. The formula
is:
the pocket x or y move > tool diameter + tool radius - fin cu t
If the tool is too large for the zigzag ramp, the ProtoTRAK SMX CNC will give an error
message during program run and will then default to plunge. This will occur for each pass of
the pocket depth.
9.6.6
Conrad in Pocket Events
A Conrad may be added to the last event of an Irregular Pocket. The Conrad will be inserted
between the end of the last event and the beginning of the next event.
9.6.7
Bottom Finish Cut
The standard finish cut is along the walls of the part, but you may have the
ProtoTRAK machine a finish cut along the bottom as well. When the highlight is on
the Fin Cut prompt, the blue ? appears next to the Help key. Pressing help gives you
the ability to choose a Finish cut in Z. You can remove the bottom finish cut by
placing the highlight on the Fin Cut prompt and pressing Help again. When you
select Yes to the bottom finish cut, the following prompt will appear:
Z FIN CUT: the finish cut at the bottom.

9.7 Islands (Advanced Features Option)
Islands programming is available as part of the Advanced Features Option. See
Section 3.1.2.
Within the Pocket event choices, you may also select a circular, rectangular or
irregular island. An island is a shape that is left standing when the surrounding
material is removed. The ProtoTRAK gives you the ability to machine almost any
shape as an island within a rectangular pocket. Both the shape of the island and the
dimension of the surrounding pocket are defined within the island event.
The tool path for machining the island event is that the tool will first plunge or ramp
into the material next to the island, offset by the programmed finish cut, to the depth
of the first pass. The tool will machine the perimeter of the island, offset by the
island finish cut. Then the tool will machine the material in the pocket in a spiral
path, moving away from the island in the programmed clockwise or counterclockwise
direction. It will continue this outward spiral motion until it encounters the
programmed rectangular perimeter (or pocket). It will then follow t he perimeter,
offset by the pocket finish cut.
It will proceed in this manner through the number of programmed passes. On the
final pass, it will machine the island finish cut, then the pocket finish cut. If a Z finish
cut is programmed, it will do this in the same spiral pattern as the roughing passes
between machining the island and pocket finish cuts. The tool will ramp away from
the finish cut by the amount of the finish cut before it raises out of the part.

9.10 Subroutine Events
The Subroutine Events are used for manipulating previously programmed geometry
within the XY plane.
The Subroutine Event is divided into three options: Repeat, Mirror, and Rotate.
Repeat and Rotate may be connective. As long as the rules of connectivity are
satisfied (see Section 5.9), the ProtoTRAK SMX CNC will continue milling between
preceding and subsequent events.
REPEAT allows you to repeat an event or a group of events up to 99 times with an
offset in X and/or Y and/or Z. This can be useful for drilling a series of evenly spaced
holes, duplicating some machined shapes, or even repeating an entire program with
an offset for a second fixture.
Repeat events may be "nested." That is, you can repeat a repeat event, of a repeat event, of
some programmed event(s). One new tool number may be assigned for each Repeat Event.
MIRROR (Advanced Features Option) is used for parts that have symmetrical
patterns or mirror image patterns. In addition to specifying the events to be
repeated, you must also indicate the axis or axes (X or Y or XY are allowed) that the
reflection is mirrored across. In addition, you must specify the offset from absolute
zero to the line of reflection. You may not mirror another mirror event, or mirror a
rotate event. Consider the figure below:
FIGURE 9.10.1 Holes 1-4 are mirrored across the Y axis to 5-8, respectively, about a line X OFFSET from
X=absolut e 0
ROTATE is used for polar rotation of parts that have a rotational symmetry around
some point in the XY plane. In addition to specifying the events to be repeated, you
must also indicate the absolute X and Y position of the center of rotation, the angle
of rotation (measured counterclockwise as positive; and clockwise as negative), and
the number of times the specified events are to be rotated and repeated. You may
not rotate another rotate event, or rotate a mirror event. Consider the figure below:

XYZ Machine Tools Ltd. and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
FIGURE 9.10.2 Shape A programmed with 4 MILL events and Conrads. Using ROTATE, these 4 events are rotated
through a 45 degree angle about a point offset from absolute zero by X Center and Y Center
dimensions. A is rotated 3 times to produce shape B, C, and D
Press the SUBROUTINE (SUB) soft key to call up the Repeat, Mirror, and Rotate options.
9.10.1 Repeat
Press the REPEAT soft key.
Where:
First Event #: is the event number of the first eve nt to be repeated.
Last Event #: is the event number of the last event to be repeated; if only one
event is to be repeated, the Last Event # is the same as the First Event #.

Y Offset: is the incremental Y offset from event to be repeated.
Z Offset : is the incremental Z offset from event to be repeated.
Z Rapid Offset : is the incremental Z rapid offset from event to be repeated.
# Repeats: is the number of times events are to be repeated up to 99.
% RPM: is the percentage of RPM in the programmed events. SET will load in the
assumed % of 100%. RPM programming is available only if the Programmable
Electronic Head Option is active.
% Feed : the percentage of the feeds programmed in the repeated events. 100% is
assumed.
Tool #: is the tool number you assign.
9.10.2 Mirror (Advanced Features Option)
Press the M IRROR soft key.
First Event #: is the event number of the first event to be mirrored.
Last Event #: is the event number of the last event to be mirrored; if only one
event is to be mirrored, the last event is the same as the first.
87
XYZ Machine Tools, Ltd.
XYZ Machine Tools Ltd. and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
Cutting Order: input 1 to cut from the lowest mirrored event to the highest
(forward) and 2 to machine from the highest mirrored event to the lowest
(backward).
This way you can keep all the machine motion in a consistent direction as it moves
from the original shape to the mirrored shape and keep all cutting either climb or
conventional.
Mirror Axis: is the selection of the axis or axes to be mirrored (inp ut X or Y or XY,
SET).
X Offset: is the distance from Y absolute 0 to the Y -axis line of reflection.
Y Offset: is the distance from X absolute 0 to the X-axis line of reflection.
9.10.3
Rotate
Press the ROTATE soft key.
First Event #: is the event number of the first event to be rotated.
Last Event #: is the event number of the last event to be rotated; if only one event
is to be rotated, the last event is the same as the first.
X Center: is the X absolute position of the center of rotation.
Y Center: is the Y absolute position of the center of rotation
Angle: is the angle of rotation of the repeated events (positive is counterclockwise;
negative is clockwise).
# Repeats: is the number of times events are to be rotated up to 99.
9.11 COPY Events (Advanced Features Option)
Copy Events are programmed exactly like Subroutine Events. The only difference is
that in Copy the events are rewritten into subsequent events. If, for example, in
event 11 you Copy Repeated events 6, 7, 8, 9, 10 with 2 repeats, events 6-10 would
be copied with the input offsets into events 11 -15, and recopied into 16-20.
Copy Events may be Repeat, Mirror, or Rotate.
Copy is very useful. With Copy you can:
•
Edit the events that are being repeated, mirrored or rotated without changing
the original events.
•
Connect so that the quill will not move up to the Z Rapid position, and back
down unnecessarily. However, to be connective, you must be certain that the X,
Y, Z begin of the first event, once offset or rotated, coincides with the X, Y, Z
end of the last event.
•
Program an event parallel to X or Y (where the geometry is the easiest to
describe), rotate it to the desired position, then delete the original.
•
Use the Clipboard to paste previously stored events from another program into
the current program. After you press the Clipboard key, you will enter the
offset from the previous program's absolute zero to the current program's
absolute zero (see figure below). For information about putting events into the
clipboard, see Section 10.4.
88
XYZ Machine Tools, Ltd.
XYZ Machine Tools Ltd. and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual

Y CENTER : the Y dimension of the center of the thread.
Z RAPID : the Z dimension where the Z rapid feed slows to Z program feed.
Z BEGIN: the Z dimension where the threading pass begins.
Z END: the Z bottom of the thread.
PITCH: the distance from one thread to the next in inches or mm. It is equal to one
divided by the number of threads per mm or inch. For example, the pitch for a M5 x
1mm screw is 1 mm. For Imperial units, it is equal to one divided by the number of
threads per inch. For example, the pitch for a 1 / 4 – 20 screw is 1 divided by 20 =
0.05”.
MAJOR DIA : the largest diameter of the thread (the root for an ID thread, the crest
for an OD thread).
MINOR DIA : the smallest diameter of the thread (the root for an OD thread, the
crest for an ID thread).
SIDE: input 1 for inside, 2 for outside.
ANGLE: the angle the tool feeds into the beginning depth.
DIRECTION: clockwise or counterclockwise.

event. RPM programming is available only if the Programmable Electronic Head
Option is active.
FIN RPM: is the spindle RPM for the finish cut. FIN RPM programming is available
only if the Programmable Electronic Head Option is active.
TOOL#: is the tool number you assign.
9.13 PAUSE Events
The purpose of the Pause Event is to allow you to program a stop condition within
the program. The effect of this event is to turn off the spindle, move the head to
the Z retract location with the X and Y position corresponding to the end of the
previous event and stopping the program run.
Pause events are useful if you want to stop the program to make a measurement,
change a fixture, etc.
NOTE: In general, you should avoid programming a PAUSE event between two connective
events. The Pause event will cause the events to NOT be connective.
To program a Pause Event press the PAUSE soft key. Because there is no input
required, simply press SET to load and the event counter will advance by one and the
Select Event screen will reappear.
In run, press the GO key after a pause to continue.
9.14 Engrave Event (Advanced Features Option)
The Engrave Event allows you to machine numbers, letters and special characters as
part of a part program. See Figure 9.14 below for the letters and special characters
that are available in the Engrave Event.
When programming with the Engrave Event, the ProtoTRAK will construct a box to
contain the text you define. This box is oriented along the X axis like the text in this
sentence, and you may program up to 40 characters per event (although you will
only be able to see 20 characters on the prompts screen). To machine text in a
direction other than the X axis, simply use multiple Engrave Events and place the
lower left corner of the box wherever you would like. The numbers and letters you
program will always have a standard orientation (like the letters on this page) – you
cannot program tilted or inverted letters with the Engrave Event. The letters are of
the font shown in the figure and all capitals.
Prompts for the Engrave Event:
First, define the lower left corner of the box that will contain your text:
X BEGIN: The X coordinate of where you want your text to begin.
Y BEGIN: The Y coordinate of where you want your text to begin.
Z RAPID: The Z dimension where the Z rapid feed slows to Z program feed.
Z END: The Z dimension to the bottom of your text.
HEIGHT: The height of your text. Each character varies in width; the set height of
the character will change the width in order to keep the overall size of the character
proportional.
TEXT: The text to be milled. When you get to this prompt, the Alpha keys will
automatically pop up to allow you to enter the text. Once you have finished entering
text, you must press End (F8) and then any of the SET keys to successfully enter
your text into the event. The alpha keys will appear automatically if the text field is
blank. If you have already entered text but wish to make a change, you will see a

Tool #: is the tool number you assign.
.
Figure 9.14 The above figure shows the text and special characters available for the Engrave event.
Notice the field that is labeled “Text Length”. This field will display the total length of your
programmed text and will update as you enter each character
9.15 Finishing Teach Eve nts
Teach events are either POSN, DRILL or MILL events that are originated in the DRO
Mode (see Section 6.7).
The Teach events that are started in the DRO Mode must be finished in the Program
Mode before running. Teach events are of these different types:
TEACH POSN - for two-axis operation, the Position and Drill event types are
combined. See Section 9.1 for a description of Position event prompts.
TEACH DRILL- this may also be made into a bore event. See Section 9.2 for a
description of Drill event prompts.
TEACH MILL - a straight line that specifies the beginning and the end. When
TEACH MILL events are defined using the CONT MILL softkey, the prompts for
information that cannot change will be suppressed. See Section 9.4 for a description
of Mill event prompts.
When a Teach event is unfinished, the words NOT OK will appear next to the event
type. Once the prompts are completed, the words NOT OK and Teach will disappear.
The event will become a normal MILL, DRILL, or POSN event.

10.0 Auto Geometry Engine (A.G.E.) Programming
This entire section deals with the Auto Geometry Engine (A.G.E.), which is part of the
Advanced Features Option. If the Advanced Features Option is not active, the Auto
Geometry Engine is not available on your control. If you sometimes need to program
prints with data missing, the Auto Geometry Engine alone is worth the price of the
Advanced Features Option. See Section 3.1.2 for more information about the
Advanced Features Option.
When you program an Irregular Pocket or an Irregular Profile the A.G.E. is
automatically started.
The A.G.E. is powerful software that works behind the easy-to-use geometry
programming of the ProtoTRAK SMX CNC. It is treated in its own section because it
works differently than the other event types. Unlike other events, the A.G.E. allows
you to:
•
•

Enter the data you know, and skip the prompts you don’t.
Use different types of data (like angles) that may be available from the print.
Enter guesses for the X and Y ends and centers not available on the print.
With the A.G.E., you can easily overcome limitations in the data the print provides

10.1 Starting the A.G.E.
The A.G.E. is started automatically when you enter the Irregular Pocket or Irregular
Profile event. The first set of prompts you encounter will be the header information.
Once that information is entered, you will see the following screen:
FIGURE 10.1 Once the profile header screen is finished, you choose between an A.G.E. Mill and an A.G.E.
Arc to define the shape. Two-axis CNC programming will not require Z data. *
Where:
A.G.E. Mill: A straight line from one X Y point to another.
A.G.E. Arc: Any part of a circle.

In addition to the normal Softkeys, this additional one will appear in A.G.E. Arc
programming:
GUESS: this softkey will appear when the prompt is on X or Y dimensioned data.
Press the Guess key before you press INC SET or ABS SET to enter the data as a
guess. See Section 10.7.
10.4 Skipping Over Prompts
In the A.G.E., events don't have to be fully defined before you can go to the next
one. You can skip the data you don’t know by using the DATA FWD softkey. After
you press the DATA FWD key at the last prompt, the event will move to the left side
of the screen and the Select Event screen will appear.
When skipping over prompts or editing, always use the DATA FWD or DATA BACK
key. Using INC SET or ABS SET will change the data.
If you want the event back on the right side, use the BACK hard key.
10.5 The OK/NOT OK Flag
Each A.G.E. event has a flag that tells you if it has been fully defined. Sometimes
data from later events is needed to define previous events. To the immediate right
of the event type, the words OK or NOT OK appear, depending on whether that
particular event is defined.
Once the OK flag appears for the event, you do not need to enter more information.
Skip past the rest of the prompts with the DATA FWD softkey.
If you leave the Program Mode and then return, pressing the GO TO END softkey will
take you automatically to the first NOT OK event.
10.6 Ending A.G.E.
Any time all the events are of an Irregular Profile are OK, the A.G.E. may be ended.
If you are programming an Irregular Pocket, there is an additional requirement that
must be satisfied before the A.G.E. may be ended: the X and Y end point of the last
event must be the same as the X and Y beginning point, so that the pocket is closed.
95
XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
Otherwise, the ProtoTRAK SMX CNC cannot program the tool path to clear the
pocket.
The Irregular Profile has no such restriction since profiles may be open or closed.
Once the A.G.E. is ended, the Irregular Pocket or Irregular Profile event is complete
and you may then choose from all the programming canned cycles from the Select an
Event screen. To reopen the A.G.E. Profile or Pocket, simply use the BACK hard key
or the PAGE FWD or PAGE BACK softkeys to position on of the A.G.E. events on the
right side of the screen. You may edit or insert other events.
10.7 Guessing Data
Whenever you are missing X or Y Ends or Centers, you should generally enter a
guess. Guessed data is treated differently by the ProtoTRAK SMX CNC than regular
data. Often, the information you put into the system will allow it to calculate a
mathematically correct line or arc that would satisfy the conditions of the hard data
you entered. This line or arc may yield more than one solution to particular point you
are looking for. That is where the Guess comes in: the A.G.E. uses the guess to
choose from the mathematically possible solutions. In most cases, your guesses do
not have to be very precise. The smaller the lines or arcs, the more precise the
guess should be.
FIGURE 10.7 The X End dimension has been entered as a guess—note the letter G
Guesses should always be entered as absolute dimensions. Once entered, the
guessed data is green and there is a 'G' next to it. Guessed data will be labeled this
way in all the events that are flagged NOT OK. Once an event is OK, the guessed
data will be replaced by calculated data. If you wish to edit your guesses, placing it
on the right side of the screen will cause your original guessed data to reappear.
10.8 LOOK and Guess
Guessed data may be entered by pressing the number keys and then SET. However,
you may find it more convenient to use the LOOK graphics to enter guesses.
96
XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
When the high light is on the prompt for which you wish to enter a guess, press the
Guess key. The Data Input Line will say "Enter Guess for X END" (for example). At
this point, press the LOOK key.
Figure 10.8.1 When the Data Input Line says "Enter Guess" pressing LOOK gives you the
ability to use graphics to make your guesses.
On the screen shown in the figure above, the Data Input Line says "Enter Guess for X
BEG". Pressing LOOK at this point will take you to a special version of the LOOK
graphics. Using a mou se or the cursor keys, you may move a point around the
screen. When you come to the place where your point is, use the Enter key.
The softkeys for this special version of the LOOK graphics:
: move the cursor around the screen.
ZOOM IN: makes the drawing larger.
ZOOM OUT: makes the drawing smaller.
ENTER END: when the cursor is at the point you want to use as a guess, use this to
enter the end point of a line or an arc.
ENTER CENTER: use this to register a guess for the center of an arc.
You can enter a combination of guessed and non -guessed data. For example, if you
were to enter the dimension for X End without guessing, you would still be able to
enter the dimension of Y End using guess.
Your guess entries are loaded into the program when you exit the LOOK screen by
pressing BACK or by pressing LOOK again. The ProtoTRAK will use the last ENTER
key press and load that into the program.
When you use the graphics to guess dimensions on arcs, you may load in guesses for
both the X/Y End and the X/Y Center before leaving the LOOK screen.
When you have not first pressed the Guess key, pressing LOOK gives you the same
screen as in regular programming. Whether you enter the guesses as key presses or
by using the graphics, the drawing of the LOOK screen distinguishes between events
that are fully defined and those that rely on guessed data. OK events are
represented by solid lines. NOT OK events are represented by dashed lines.

FIGURE 10.8.2 When the events are calculated based on Guessed data, they are represented by a dotted line
10.9 Calculated Data
Prompts that are skipped or for which guesses are entered may be replaced by data
calculated by the ProtoTRAK SMX CNC. Calculated data is shown in red in order to
distinguish it from the data that you entered. You cannot edit calculated data, but
you may edit your original input. By putting the event with the calculated data on
the right side of the screen, you may position the cursor to the prompt and re-input
the data.
10.10 Arcs and Conrads
If the print is missing a lot of data, it may be desirable to program arcs as separate
events where possible. This gives the system more information to work with.
10.11 Tangency
Tangency can occur between a mill and arc or an arc and arc. Specifically it means
necessary but not sufficient that the two geometries share one and only one. You
would answer yes to the TANGENCY prompt if the event you are programming is
tangent to the previous event. The information that events are tangent helps the
Auto Geometry Engine calculate other dimensions.
You can often tell by looking at the print if events are tangent: tangent intersections
tend to blend smoothly, without a sharp corner.
smooth, probably tangent
sharp, not tangent
For the A.G.E., the tangent mill or arc is assumed to continue in the same direction,
and not double back on the previous event:

To delete a group of events in the program, press Delete Events
The Data Input Line will prompt for the first event to be deleted. Input the event
number of the first event and press set. Next the Data Input Line will prompt for the last
event number to be deleted. Put in the last number and press Set.
The remaining events will be renumbered.
11.2 Spreadsheet Editing™ (Advanced Features Option)
Spreadsheet Editing allows you to view program inputs in a table and make global
changes to the program. This is particularly useful if you are working with a large
program and you need to make a change to many events.
When you press the SEARCH EDIT softkey, the screen will load a table that contains
data for every event. See Figure 11.2.1

11.2.3 Making Global Changes to Data
Sometimes it is useful to be able to change data in a program without having to go
through each event one at a time. For example, if you were to want to change the tool
number for every milling event, it may be a chore to go through each event in a long
program to make the changes on that event type.
In order to make global changes:
1.
Sort the data in a way that groups together the things you want to change.
2.
Highlight the data value that is highest on the table (nearest to the top) that you
want changed.
3.
Press the CHANGE ALL softkey. All the inputs that are the same as the one you
highlighted and are listed together below the data you highlighted will then be
highlighted.
4.
Enter the new value, then press set. All the highlighted data will be changed to the
value you just input.
Example:
The following example uses Z axis data for a three-axis CNC model. From the screen
shown in Figure 11.2.1, we will change the Z Feed for each of the mill events in the
program.
1.
Sort by event type to get all the Mill events together.
2.
Highlight the Z Feed in the first Mill event (Event # 8). See Figure 11.2.3.
3.
Press the CHANGE ALL softkey. All the Z Feeds in the Mill events are highlighted.
See Figure 11.2.4.
4.
Type in the new Z Feed value and press INC SET or ABS SET. See Figure 11.2.5.
In this example, the Z feed is changed from 5.0 to 7.0 for all the Mill Events.

11.3 Erase Program
Use the ERASE PROG soft key to erase the program from the current memory. Erasing
the program from current memory will not affect any programs that are stored.
If you have made changes to the program and wish to save this modified program, you
will need to store it. See Section 13.4.
11.4 Clipboard (Advanced Features Option)
The Clipboard feature is a way to copy events in one program in order to put them into
a different program. It is a two-part process that takes place in two different Modes.
First, in the Edit Mode, the desired events are copied, or placed on the Clipboard, from
the source program. Then the events are inserted into the destination program in the
Program Mode.
When you press the Clipboard key from the Edit Mode, you start the process that copies
the events that you want to put into a different program than the one in current
memory.
Before you do that, you should write a program or open the program file that has the
events you want to copy. This is called the source program.
Inspect the events you want to copy. Make sure that the dimensioned data uses
Absolute references in the first event to be copied and in all events where it will be
important. Incremental references may be used, but keep in mind where the
Incremental reference will be made from. See the section on Incremental Reference
Position in this manual.
In addition, you may want to modify this program in order to get all the events you want
together. For example, if you want to copy events 2-5 and 7-12, you may want to
modify the program to delete events 1 and 6 first. That way, you can copy the all the
events as they are now numbered from 1 to 10. Remember that you can modify this
program just for this purpose and it will not affect the original program unless you save
it with the modifications in the Program In/Out Mode.
When the source program is ready, press the CLIPBOARD softkey. A message will
appear that says "Copy Events Onto Clipboard" and the Data Input Line will read "From
Event". Enter the number of the first event that you want copied and press SET.
The Data Input Line will read "To Event". Enter the number of the last event you want
copied and press SET.
The group of events that you have specified is now on the clipboard and will remain
there until you replace it with something else by going through the same procedure.
When power is turned off to the CNC the clipboard information will also be lost.
The events on the clipboard are inserted into a program in the Program Mode. See
Section 8.11.

Click in the Find What box and enter the item you want to find. Click on the Find Next
box and the G-Code Editor will locate the next occurrence of that item. Successive clicks
on Find Next will continue to search through the program. Use Match Whole Word to
limit the search to the entire word. For example, if you want to find G2, but not G20 or
G22, select Match Whole Word Only.
Instead of typing the item into the Find What box, you may simply highlight an item on
the G-Code Editor screen. That item will be entered into the Find What box for you.
To make changes to Find What items, type what you want to have into the Replace With
box. You can replace items one at a time by clicking first the Find Next box then the
Replace With box for as many changes as you want to make. You can replace every
item in the program with a single click of the Replace All box.
Return closes the G-Code Editor and returns the screen to the Edit Mode.
Note: If you use the USB Thumb Drive to store a G-code (.gcd) program file, you must
leave the Thumb Drive plugged into the USB port the entire time the program is in
current memory. If you unplug the thumb drive with the program still in current
memory, the ProtoTRAK will display an error message.

12.1.1
The Tool Table Screen
When you first enter the tool table by pressing the TOOL TABLE soft key, you will see the
screen shown in Figure 12.1.
Tool #: the number of the tool from 1 to 99. Tool numbers shown in red are active for the
program in current memory.
Diameter: the diameter of the tool.
Z Offset: the difference between the Z position of the tool and the Z position of the
reference. The Z offset is always relative to a reference point. Before the reference point
is set, the highlight will not go into the Z Offset column because setting a Z offset before
the Z reference is set has no meaning.
Z modifier: a value you enter to make adjustments for the tool depth. See 12.1.7 below.
Tool Type: allows you to select the type of tool from a list. Input the number that
corresponds to the desired name (eg 1 = Drill) and press SET. The tool name will be in
the prompt at the beginning of the program Run.
Ref: the reference position for the Z offset. Before the reference position is set (and the
Ref row reads "NOT SET") the highlight will not go into the Z Offset column. Once set, the
highlight will not go into the Ref row, that is, you will not be able to highlight and reset your
reference once it says "SET".
The soft keys in the tool table:
DATA DOWN, DATA UP, DATA LEFT, DATA RIGHT: move the highlight around the table.
ERASE TABLE: clears all tool information so you can start over. See 12.1.4 below.
JOG: puts the ProtoTRAK SMX CNC into the DRO jog operation (see Section 6.3).
RETURN: reverts to the SET UP mode screen.
The electronic handwheels are active, including the fine/coarse selection, while you are in
the tool table.
12.1.2
The Logic of the Tool Table
For three-axis CNC models, the diameters and Z Offsets must be set up for each tool. For
two-axis CNC models, the diameter is essential for the tool compensation to work, but the
Z Offset information is not mandatory. However, even in two-axis or DRO operation, Z
Offset information will be applied to the Z-axis DRO dimension for each tool, saving you the
need to touch off every time the tool is changed.
The tool table is organized to do the following:
• Make it easy to set up tools.
• Make it easy to replace a tool or add a tool.
• Retain tool information in memory to reduce set-up.
You assign tool numbers as you write a program. These tool numbers may be from 1 to
99. Before machining, the diameters and Z offset of each of the tools in the program must
be defined so that the ProtoTRAK SMX CNC can calculate the tool path. Tools that are
used in the program that is in current memory are called active tools and their numbers
are in red in the tool table.
When you save a program, all the tool information for active tools is saved with it. When
the program is opened, the tool information is put into the tool table. This information will
replace any information that already is in the tool table for the same tool numbers.
In addition to information about the tools used in a program, you may load in information
for tools to be used in 2-axis CNC or in the DRO mode for machining manually. When you
tell the ProtoTRAK SMX CNC which tool you are using, it will adjust the Z DRO dimensions
accordingly so you don’t have to touch off and reset after a tool change.
The idea of retaining tool information in memory in order to reduce the amount of set-up
needed requires that care be taken to avoid mistakes. Milling work usually requires a lot of
108
XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
tools, many of which are not preset into fixed tool holders. That means tool information
that is not very recent is probably no good.
Think of the information in the tool table this way: if you clearly remember setting the
tools and entering the diameters very recently, then use the tool table in DRO and CNC run.
If you can't remember setting the tools clearly, erase the table and start over – it only takes
a moment.
This may cause some confusion because the normal sequence for running a two-axis
program is to load in a tool, touch it off and set zero, then press GO. The ProtoTRAK SMX
CNC will apply the tool offset after the GO press, making the Z dimension meaningless.
You have two choices:
1.
Use the tool table, setting the reference and absolute dimension for one of them per
the instructions above. This will save you from having to touch off tools every time
they are changed in program Run.
2.
Don’t use the tool table. Erase the entire tool data so that the ProtoTRAK SMX CNC will
not try to apply offsets.
12.1.3
Initial Tool Set-Up
This procedure is used for setting up tools when the tool table is clear.
1. When you enter this screen for the first time, the words "NOT SET" appear directly under the
Z OFFSET column in the REF row. The Data Input Line reads "TOUCHOFF REFERENCE
POINT". This is prompting you to establish a reference for the rest of your tools.
2.
To establish a reference, put a cutting tool or some other reference setting tool into
the spindle and touch the tool to a surface. We recommend that you use something
besides a tool that you intend to use machining the job. Ideally, you will have a
reference tool that you keep handy for setting up your tools every time. That way, a
reference point can be easily re-established later.
3.
We also recommend that you use the top of the vice or table as your reference
surface because it is constant and never changes.
4.
With the highlight on the screen on the words "NOT SET" and the tool touching some
reference point, press SET.
NOTE: If you do use a tool as your reference tool and it breaks, you must retouch off all tools.
5. The words will change from "NOT SET" to "SET" and the highlight will shift to the
DIAMETER column of Tool # 1. (Note that you may not be interested in setting up
Tool #1 if it is not one of the active tools of the program. If this is the case, use the
DATA softkeys to move to a tool you are interested in.).
6.
Input the diameter for the tool and press SET.
7.
The highlight will move to the Z OFFSET column. Put this tool in the spindle and
touch it to the same surface as you used to touch the reference tool in Step 2 above.
Press set.
8.
9.
The highlight moves to the Z Modifier column. Input and set a Z modifier if you wish
(see below) or simply press SET to input no modifier.
10. The highlight moves to Tool Type and a green window appears with your choices.
Input 1 to 9 corresponding to your choice and then SET. This moves you to the
Diameter input for your next tool.
11. Repeat steps 5 to 8 for each of the tools you want to set up. Remember to touch
the same surface you used to set the reference tool.
Once the reference position is set, you will not be able to move the highlight back to the
word "SET".
Note: You must set an absolute zero reference in the DRO Mode before machining the part. You
may use any tool that you have set up with the above procedure to set your reference and the
ProtoTRAK will automatically compensate for the difference in length for the rest of the tools.

12.1.4
Starting Over: Erasing Tool Information
There will be times when you don't completely trust the information that is in the tool table.
For example, perhaps you have loaded in a program that you wrote a month ago and you
recall that one of the tools you used was held in a chuck. In that case, you probably want
to erase the table and start over.
In order to do this, simply press the ERASE TABLE softkey and answer yes to the prompt.
All the data in the tool table will be erased including the reference. The numbers of the
tools used in any program in current memory will still be red.
12.1.5
Adding a Tool
When the reference is SET and the original touch-off surface is still available, you can add
a tool very easily:
1.
First make the tool number active by using it in the program in current memory.
2.
Put the new tool in the spindle.
3.
Go to the Set-Up Mode, tool table
4.
Enter the diameter.
5.
Touch the new tool to the same surface as the reference.
6.
Press SET.
If the surface is not available, it will be necessary to establish a new reference before
adding the new tool. See Section 12.1.8 below. Once the reference is reset, use the
procedure above on the new surface used to set the reference.
12.1.6
Replacing a Tool
If you need to replace a tool that was not used as the reference, simply do the following:
1.
Put the replacement tool in the spindle.
2.
Put the highlight in the correct row for the tool number.
3.
Reenter the diameter if different.
4.
Touch the tool to the same surface that was used to touch off the reference.
5.
With the highlight in the Z OFFSET column for the correct tool number, press SET.
If you need to replace a tool that was used as a reference, we recommend that you press
the ERASE TABLE softkey and start all over again. (Not to nag, but that is why it is a good
idea to have a separate reference setting tool and use a constant reference surface. If you
work with programs that use a lot of tools, this practice can really save time.).
12.1.7
Z Modifiers
Z modifiers make it easy to adjust the depth of cut of particular tools without having to
change programmed Z end dimensions or change the tool offsets.
For example, say an end mill was under cutting the depth of a part by .01mm. An easy
way to correct this is to enter a Z modifier.
1.
Highlight the number in the Z MODIFIER column in the row for the correct tool.
2.
Enter the amount of the adjustment you wish to make. To cut deeper, enter a
negative number. To cut shallower, enter a positive number. In the example above,
to correct this undercut, we would enter -.01mm.
3.
Press SET.
The ProtoTRAK SMX CNC will apply this modifier each time this tool is used.

12.1.8
Resetting the Reference Point
Once the reference reads SET, you are not allowed to highlight and reset it. If you need to
reset the reference, there are two ways to change the reference to NOT SET. You can
erase the table (and lose all the tool information) or load in a program.
12.1.9
Saving Tool Information
Tool information is saved with the program. If you have made changes to the program or
to the tool table that you wish to keep, you must save, or store, the program in the
Program In/Out Mode.
12.1.10 Opening a Program
When you open a program, the tool information that is saved with the program will be
loaded into the tool table. The numbers for the tools that are used in the program are in
red. The diameters, Z Offsets and Z modifiers that were saved with the program will
overwrite any information that was in the tool table before the program was opened. If
these tools were not set very recently, we recommend that you check them before running
the program.
The Ref row will read "NOT SET". A reference may be set at this point.
If you do not go into the tool table after opening a program and before running, you will get
a reminder message to check your tools.
12.1.11 Making Tool Set-Ups Easy
We highly recommend the following to make tool set-ups easy.
1.
Always use the same tool to set your reference. Preferably, you should use a tool you
don’t use to machine, something that you keep in your toolbox.
2.
Don’t use a tool that you use to machine your part as a reference. If your reference
tool breaks, you have to reset all your tools.
3.
Always use the same surface for touching your tools to. Use the machine table, a gage
block or the vice, something you can always count on being there. If you use the top of
the part, your reference is changing all the time.
12.1.12 The Tool Table and Two-Axis CNC Operation
The information entered in the tool table will also be used when operating the ProtoTRAK
SMX CNC as a two-axis CNC. Instead of positioning the head, the DRO information seen in
the Run Mode will be adjusted for the differences in tools. When a new tool is loaded, the Z
dimension will change according to the offsets in the tool table. This change will occur
when the GO key is pressed after the "Load Tool # ___" prompt.
111
XYZ Machine Tools, Ltd.

12.2
Tool Path
When the TOOL PATH soft key is pressed, the program is processed and the tool path
graphics are displayed.
i01143
FIGURE 12.2 The Tool Path graphics show the program and tool
positions. Three-axis CNC graphics are shown above. Two-axis
graphics will be simpler.
Most programming errors that would prevent the program from running are detected when
the tool path graphics are selected. For example, if you were to have omitted a minus sign
from a Z End dimension, the system would give you an error message that the Z End
should not be higher than the Z Rapid.
The displayed graphic is automatically sized to fit the screen and an icon that represents
the X, Y and Z orientation is placed at the program's absolute 0 reference point. The path
shown on the screen represents the cente r of the tool.
•
Position and drill events are drawn in yellow.
•
Rapid moves are in red.
•
Programmed geometry is in blue.
12.2.1
Soft Keys in Tool Path
ADJUST VIEW : calls up additional softkeys to adjust the view. See below.
FIT DRAW: will re-draw, automatically sizing to fit the screen (necessary only if an
adjustment changed the drawing from its initial sizing).
STEP: each press of the STEP button shows the next tool move. You may hold the STEP
button down to draw the graphic without repeated button presses. To complete the
drawing automatically, press FIT DRAW.

12.3 Reference Positions (REF POSN)
The Reference Positions screen for three-axis CNC models shows the retract status, the
home locations and software limits for all axes. For two-axis models, only the X and Y
limits are shown.
FIGURE 12.3 Reference positions for three-axis CNC models. The Z Retract is not set.
Position the head and press a SET key
12.3.1
Z Retract (Three-Axis CNC Models)
The Z Retract is where the head will go for a tool change or at the end of running a
program. Programs may not be run in three-axis CNC until the Z Retract is set. Since the
Z-axis (head) is operated manually in two-axis CNC, it is not necessary to set the Z retract
to run a two-axis CNC part.
As a general rule, always set your Z retract so that your longest tool is above the set-up.
When you first enter the Reference Positions screen, the Z Retract will show "NOT SET"
and the message window will instruct you to move the quill to the desired retract position
and then press SET. You may have to go into the DRO Mode to move the quill to where
you want it and then return to the Reference Positions screen to set this position.
12.3.2
Home Positions (Three-Axis CNC Models)
X and Y home positions are where the table and saddle go when there is a tool change
or at the end of the program. These dimensions must always be from absolute zero. Note
Z home is the same as Z Retract.
113
XYZ Machine Tools, Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
12.3.3
Limit Positions
X and Y limit positions (one for plus direction, one for minus) will stop the program if they
are exceeded during run. Note that pressing the LIMIT ON/OFF soft key will turn the
prompted limit off, or back on to its input value. If the limits are turned on, your program
and home positions must fit within the limits you define. If you turn on the limits and leave
them at the default of 0 Absolute, the program will not run.
12.4 Fixture Offsets (Advanced Features Option)
Fixture offsets are entered in the Set-Up Mode. From the screen in Figure 12.0, press the
Fix Offset key. The following screen will result.
Figure 12.4 The Fixture Offset screen.
Setting up fixtures is easy. First, establish your base by setting your X, Y and Z absolute
zero. You can do this in the DRO Mode, but the X, Y and Z Absolute position dimensions
are also on this screen for your reference. Fixture #1 is always the base.
Once you set your absolute zero on the base, it is simple a matter of entering the distance
from the base to up to five other fixture locations. You can do this one of two ways. By
entering the numbers with the keypad or by positioning to the next fixture, putting the
cursor on the correct offset value, and then pressing ABS SET.
12.5 Service Codes
These are special codes that may be entered into the ProtoTRAK SMX CNC to call up
routines used in installation, setting of preferences, machine checkout and service.
WARNING!
Before using service codes, be aware that some of the routines are very powerful and may change
system settings in a way you don't want. Some of the routines cause
the servos to come on and move at rapid speed.
The Service Codes are divided into logical categories. The table below summarizes the more
important ones. See the service manual for more information on using Service Codes.

13.2 Two Versus Three-Axis Running
For three-axis CNC models, the three-axis run will control all three axes. Three-axis
models also allow you to run two-axis programs. When you run two-axis programs with
either a two- or three-axis CNC model, the ProtoTRAK will control the X and Y (table
and saddle) only, with you manually positioning the Z (quill and/or knee).
Most differences that occur as a consequence of either two or three-axis operation are
obvious. Two issues are worth noting:
117
XYZ Machine Tools Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
1.
The way the tool table works between two and three-axis operation. See Section 12.1.2.
2.
Positioning of the Z axis is automatic in the 3-axis CNC, but in two-axis, the ProtoTRAK SMX
CNC will prompt “Check Z” before a rapid move and “Set Z” for you to position the cutter to
the machine part.
13.3 Starting to Run
Before running a part, you must establish the position relationship between the part and
quill. That is, you need to identify where the part is on the table relative to the tool or
quill centerline.
This is done by using an edge finder or dial indicator to move the table so that the part
program absolute zero is under the quill centerline. ABS SET this position as absolute
zero in the DRO mode. In addition, load the tool for Event 1 and position it at Z absolute
zero. If this is impossible, position the tool some known distance above absolute zero
and ABS SET this dimension.
The program may be started in the two ways identified as soft keys in the screen in Section 13.1
Pressing the START soft key begins the program at Event 1 and assumes that the
absolute zero that was last set in the DRO mode corresponds to the part program zero.
That is, if you were in the DRO mode and you moved the table to X=0 ABS, and Y=0
ABS the part program zero would be directly under the quill centerline.
Pressing the START EVNT # soft key allows you to start in the middle of a program.
When you press the START EVNT # soft key, the conversation line will prompt "Input
Event #." Input the number of the first event you wish to run, and press SET. If the
START EVNT # is a Repeat or Rotate, the conversation line will prompt "Starting Repeat
Number" asking which repeat or pass you wish to start.
13.4 Program Run
When you have started by any of the means above, the display will show:
i01145
FIGURE 13.4 Press the GO feed key to start running.
118
XYZ Machine Tools Ltd.
XYZ Turret Mill andProtoTRAK ® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
Where:
The part number being run is shown in the status line.
• The event number and type (and the repeat number, if applicable) being run is
shown at the top of the screen.
•
The current X, Y, Z absolute positions are shown in the information area.
• The SHOW ABS soft key (which is automatically assumed if one of the other 3
show keys are not selected) will show the absolute X, Y, Z positions as the part is run.
• The SHOW INC soft key will show the incremental (or distance to go within the
event) X, Y, Z positions as the part is run.
•
The SHOW PATH soft key will show the tool path graphics as the part is run.
• The SHOW PROG soft key will show the programmed data for the event being run,
and the next event as the part is run.
The run procedure is very simple. Follow the instructions on the conversation line and
proceed by pressing the GO key.
Once the STOP hard key is pressed, additional softkeys will be available:
TRAKing – select this softkey to control the X, Y and Z programmed motion with the
table or saddle handwheel. See section 13.5 below. The TRAKing/Electronic
Handwheels Option must be active for this function.
CNC Run – select this softkey to start the CNC run.
13.5 TRAKing (TRAKing/Electronic Handwheel Option)
TRAKing is a special kind of CNC run. When you press the TRAKing softkey, the
programmed head, table and saddle motion is controlled by turning the table or saddle
electronic handwheel. Moving the X or Y handwheel in the clockwise direction moves
forward through the program; moving counterclockwise moves backward through the
program. To TRAK slowly, use the Y handwheel. To TRAK quickly, use the X
handwheel.
TRAKing comes in handy whenever you are a little unsure about any aspect of your
program or set-up. For example, on the first run of a part - instead of pressing GO and
holding your hand on the stop button, use TRAKing to bring the tool to the part while
you watch the DRO. Once assured that everything is all right, press STOP and get into
CNC run.
The table guard must be closed to use TRAKing.
13.5.1
TRAKing in Two-Axis CNC
When running the ProtoTRAK SMX as a two-axis CNC on a three-axis CNC model, TRAKing
works with the manual operation of the Z. The tool may be put in position when the
messages "Set Z" or "Check Z" appear. When TRAKing through an XY move, the Z-axis
handwheel is not active.
13.6 Program Run Messages
While in the Run Mode, clear instructions and prompts from the SMX CNC will tell you
exactly what to do to run the program. These messages will appear in a green box in the
middle of the screen.
When a tool change is required, the tool information entered in the Tool Table will appear
in the green box.
Any Event Comments you entered during programming will appear on the Data Input Line
(See section 7.3.2 to use Event Comments). The Event Comments feature is part of the
Advanced Features Option.
Once the program starts, a Run Time Clock will appear in the center of the status line at
the top of the screen. This clock displays the time remaining until the end of the program
or the next tool change, and will count down as the program is run. The Run Time Clock is
119
XYZ Machine Tools Ltd.
XYZ Turret Mill and ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
part of the Advanced Features Option. Note: the program must first be viewed as Tool Path
in the Set Up Mode to initialize the Run Time Clock. Otherwise it will show 0.00. (Section
12.2)
Figure 13.6 The Run Time Clock is in the center of the status line.
13.7 Stop
At any time, the program may be halted by pressing the STOP key. This
freezes the
program at that point. You may choose to continue running the program by pressing the
CNC RUN softkey or pressing the GO key. If the Advanced Features Option is active, You
may also run the program by using the table or saddle handwheels by pressing the
TRAKing softkey.
13.8 Feedrate and Speed Overrides
In program Run Mode, the programmed XYZ axis feeds as well as the rapid speeds may
be adjusted temporarily. Likewise, if the Programmable Electronic Head Option is
installed, the programmed spindle speed may be adjusted temporarily.
You may override the spindle speeds or feeds with the OVERRIDE display hard key.
Press the F / S key until the LED is lit on the side corresponding to the speed you wish to
override (S for Spindle, F for feed). Use the up and down arrow keys to change the
feedrate in 10% increments per button press, and the spindle speed in 5% increments.
13.9 Trial Run
Trial Run allows you to quickly check out your program (with no Z movement for threeaxis CNC programs) before you actually start to make parts. In trial run the table will
move at rapid speed regardless of what feedrates are programmed (the rapid speed
may be overridden with FEED and FEED keys). The table will stop at each "stop"
location (for example, at each drill location) but immediately continue on without your
input.
To do a trial run, press the TRIAL RUN soft key from the screen shown
in Section
13.1. The message box will read "Ready to begin trial run. Press GO to start." Be
certain the table is positioned so that if it moves through the part program, it will not
reach its travel limit. Also check that the quill is fully retracted. Press GO to begin.
13.10 Data Errors
In order to run, a program must make sense geometrically. For example, you can't
machine a 10mm diameter circular pocket using a 20mm end mill.
Data errors will nearly always be detected when the ProtoTRAK SMX CNC runs through
a program--either as a Trial Run or on an actual part run. They may also be detected
in the Set Up mode when using the Tool Path Graphics routines.
Whenever the ProtoTRAK SMX CNC detects a data error a message will appear that will
tell you the error number (you may wish to record this number for troubleshooting
purposes) and the event where the error was detected. This is not necessarily the
event that is in error since the system often "looks ahead" to make sure there is
compatibility from one event to another.
In addition, an explanation is given for each data error type as well as a suggested
solution. Press the RETURN soft key to go back to the Select Mode screen, correct your
error, and proceed.

When you enter the Program In/Out Mode, this will be the name of the file in current
memory. If there was no program in current memory, the first program name on the
list will appear there. When you select another file from the list, the name will
appear here.
Open/Save As
This is the file type.
See Section 15.0 for an explanation of Filenames and File Extensions.
Blue ?
This indicates that the alphabet matrix is available for entering file names.
The Softkeys will be explained in the sections below.
14.3 Basic Navigation
Use the first five softkeys to move about the screen.
Tab: moves the highlight from section to section on the screen.
Data Fwd: moves the highlight forward through a list, such as the list of programs
in figure 14.1
Data Back: moves highlight backward through a list.
Page Fwd: if your list of programs is too large to fit on the screen, this will move
forward through the “pages” of the list.
Page Back: moves backwards through the pages of the list.
14.4 Opening a File
To open a program from the list, simply place the highlight on the program and press
the OPEN softkey. Opening a program will move it from the floppy to the current
memory of the ProtoTRAK SMX.
14.5 Saving a File
To save a file that is in current memory, press the SAVE softkey.
You will usually want to do this after you put a significant amount of work into
writing a program. Before you press the SAVE softkey, you should make sure that
the program name doesn’t already exist on the list. If you save a new program over
one that was already there, the previous one will be lost.
Once the program name appears on the list, it is stored on the floppy. If you make
changes to the program, you must save it again for the changes to be stored.
14.6 Deleting a File
To delete or remove a program from the list, put the highlight on the program and
press the DELETE key. A warning will appear in order for you to confirm you want to
delete the file.

14.7 Renaming or Copying a File
To rename a file, simply highlight the original file so that the name appears in the File
Name box. Tab to the File Name box and enter a new name. When you Tab to the
File Name box, the Blue ? appears, indicating that you can use the alphabet matrix to
help name the file by pressing the Help hardkey.
Once you type in the new name, press the SAVE softkey. Two files will now be on
your list, the new and the previously-named versions of the file you copied.
14.8 Backing Up
We highly recommend that you back up your floppy disk regularly. The easiest way
to do this is to take the floppy out and go to another computer to copy the program
files to another floppy or to a hard drive.
Floppies and floppy drives fail on occasion. It is a good practice to protect your hard
work by cultivating the habit of backing up your files.

Networking/Memory Option active. If you do not have the Networking/Memory Option, see
Section 14.0 for the operation of the Program In/Out Mode in the basic system.
If you have the Networking/Memory Option, but wish to use the system in the more simple
configuration described in Section 14.0, do Service Code 334 for the screen that turns the
option off.
If you have the Networking/Memory Option installed but not active, do Service Code 334 for
the screen that turns the option on. If you do not have the Networking/Memory Option
installed, see Sections 3.1.3 and 3.1.7 for more information about buying the
Networking/Memory Option.
From the Select Mode screen, press the PROG IN/OUT softkey. The first screen you see will
ask:
“LIST SUPPORTED PROGRAMS ONLY?”.
With a highlighted YES or NO.
FIGURE 15.0 Supported programs are part programs that can run on the ProtoTRAK SMX CNC. You do
not have to answer this question every time you are at this screen. Simply press the
softkey for the operation you want.
Supported programs are the programs that will run on your ProtoTRAK SMX CNC. It is
possible to view other types of files through the Program In/Out Mode, for example, Microsoft
Word ® files. This type of file is not supported on the ProtoTRAK SMX CNC in the sense that
you cannot open it and work on it. We recommend a “Yes” response to this prompt
Filenames and File Extensions
Most places in the ProtoTRAK SMX CNC, we refer to the program or part. In Program In/Out
Mode, this program or part is called a file. Filenames are program names or part names.
They are the name you give to the programs you write on the ProtoTRAK SMX CNC, plus a
file extension. Although the ProtoTRAK SMX CNC can have program names up to 25
characters that use letters and special symbols, most other CNC’s must have file names that
are eight or fewer characters using numbers only.
127
XYZ Machine Tools Ltd.
XYZ Turret Mill & ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
File extensions are part of filenames that help describe the file. They appear after the
filename and are composed of three letters following a period. For example, .doc is the
extension that appears after a file name for a file st ored using Microsoft Word™.
Usually, but not always, the file name indicates what program was used to create the file.
Sometimes this is not the case. Some programs, like those found in early models of CNC, do
not attach a file extension to a file name at all. Also, a user may attach his own extension to
a file name for his own purposes.
ProtoTRAK and TRAK A.G.E. CNC’s always attach an extension to every file that is stored.
The extension .MX2 is used for files, or programs, (written and) stored on a ProtoTRAK MX2,
ProtoTRAK M2 or TRAK A.G.E. 2 CNC. The extension .MX3 is used for the ProtoTRAK MX3,
ProtoTRAK M3 and TRAK A.G.E. 3 CNC’s. The ProtoTRAK SMX CNC uses the extension
.ProtoTRAK4, whether the program is two or three-axis. (Before opening the file, the
ProtoTRAK SMX CNC is able to determine what kind of file it is.)
A file extension that is unique to the ProtoTRAK SMX CNC is .GCD. The .GCD extension tells
the ProtoTRAK SMX CNC that a particular program is a standard RS274, or G Code program.
When you specify this extension, the ProtoTRAK SMX CNC will treat that program in a special
way. This is explained in Section 15.11.
15.1 Softkey Selections in the Program In/Out Mode
YES: to display only supported programs.
NO: to display all files.

Softkeys in the Program In/Out Mode Screens
Use the softkeys to move around any of the screens in the Program In/Out Mode:
TAB: Moves the highlight between the parts of the screen. Where applicable,
tabbing to an area will cause a drop-down box to appear, showing all the selections
possible.
DATA FWD, DATA BACK: Moves the highlight up and down through the list. Press
and hold for automatic advancement.
OPEN FOLDER: Use this key to open a highlighted folder that contains program
files. When the highlight is on the root directory, this will collapse the list displayed
and show the next level up. The root directory is represented by a folder with an up
arrow followed by two periods. The root directory will disappear when the most
basic organization for the drive in the Look In box is reached.
15.3 Opening a File
To open a program file from a storage location, press the OPEN softkey from the
Program In/Out Mode screen. The ProtoTRAK SMX CNC will always default to the
last folder you had open.
Find the file using the softkeys as described above in the section on basic navigation.
When a program file name is highlighted, press the LOOK hard key to see a graphical
representation of the part program. The graphics are not a precise representation of
the tool path, but should be very handy in helping to identify a file before opening.
In addition to the basic parts of the screen described above, two additional parts of
the screen appear in the open operation:
File Name: - Displays the name of the file that is highlighted from the list.
Open As: - lists the format s for which the file may be opened. The default is
ProtoTRAK4.
Two additional softkeys appear:
OPEN FILE: Opens the highlighted program file and puts it in current memory.
Only one file may be in current memory at a time, if one is there already, a warning
message will appear before that file is overwritten.
RETURN: Returns to the Program In/Out Mode screen.
When the open operation is finished, the system will return to the Select Mode
screen.
15.3.1
Preview Graphics
As an aid to finding the file you want to open, the ProtoTRAK SMX allows you to look
at the part graphics before opening. Simply select the file and press the LOOK
hardkey. The screen will show the part graphics. Press LOOK again or RETURN to
revert back to the Program In/Out screen.
The g raphics displayed in this process are not exact, but are a handy representation
of the program.

15.8 Backing Up
In order to protect your important programs, it is a good idea to back them up
regularly. That way, if a floppy disk or hard drive becomes unusable, you will not
have to re-write the program.
To back up your files, press the BACK UP softkey from the Program In/Out Mode
screen.
FIGURE 15.8 Backing up. The top part of the screen shows all the items in Drive A.
The bottom part shows the items that have been picked for backing up
The basic procedure for backing up is:
1.
Use the navigation procedure described in Section 15.2 above and highlight the
program file or folder you wish to back up.
2.
Press the BACKUP FROM softkey. You will see the item appear, along with its
directory path, in the new listing area under the main listing area.
3.
Repeat the above for as many item s as you wish.
4.
Use the navigation procedure to select a different drive or a different folder.
5.
Open the drive or folder using the Open folder key.
6.
Press BACKUP TO.
When the back up operation is completed, you will see the items and their directories
in the new location.
Note: It is good practice to back up files to a different drive, rather than to a different folder
on the same drive. For example, if you keep your programs on the ProtoTRAK SMX CNC
flash drive, it is a good idea to back them up on a floppy disk or to another computer that is
networked into the ProtoTRAK SMX CNC. That way, if the ProtoTRAK SMX CNC flash drive
becomes unusable, you will have the part programs somewhere else so that you can reload
them when the problem with the ProtoTRAK SMX CNC flash drive is resolved.
15.9 Converters™
Converters are programs within the ProtoTRAK SMX CNC that translate CNC program
files of another format into a ProtoTRAK SMX CNC file, or a ProtoTRAK SMX CNC file
into a different format. With converters, you can run programs written on the
133
XYZ Machine Tools Ltd.
XYZ Turret Mill & ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
ProtoTRAK SMX CNC on a machine that does not have a ProtoTRAK SMX CNC and
vice versa.
Each ProtoTRAK SMX CNC comes with converters for other ProtoTRAK and TRAK
CNC’s. Converters for other brands of CNC’s are sold separately.
Program conversions take place by first translating the file into a neutral run engine,
then from neutral to the desired file format. For this reason, you should think of
conversions as being only one way. The conversion process changes the file in ways
that are harmless and so the results are correct. However, when converted back, it
will not be the same as it was originally written; it will create the same part, but
some of the lines of code will be different.
15.9.1
Activating Converters
Converters must be activated before you can use them. Standard converters include
those that handle the translation between the ProtoTRAK SMX CNC and other TRAK
CNC’s. Optional converters are purchased separately. Standard converters and
optional converters that are ordered and shipped with the machine are activated at
the factory.
You can tell which converters are activated by looking in the Open As (see Figure
15.9.3) or Save As windows (see Figure 15.4).
If you purchase a converter after you have installed your machine, you must activate
it yourself using the procedure described in Section 3.1.7.
15.9.2 Converting From a Different Format into a ProtoTRAK
SMX CNC
Conversions from a different format into a ProtoTRAK SMX CNC occur when the file is
opened.
FIGURE 15.9.2 Use the Open As box to tell the ProtoTRAK SMX CNC what kind of file it is
Use the Open As box to tell the ProtoTRAK SMX CNC what format the file is in so that
it knows how to convert it to the ProtoTRAK SMX CNC format. In Figure 15.9.1 the
ProtoTRAK SMX CNC could guess that the file to be converted was from a previous
version of ProtoTRAK because of its file extension (.mx3). But since file extensions
134
XYZ Machine Tools Ltd.
XYZ Turret Mill & ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
may be missing or may not really describe the file format correctly, you can use the
Open As box to declare the file type.
All files, or programs, open on the ProtoTRAK SMX CNC as a .PT4 file (with one
exception, G-Code files, see below). Once the file is opened as ProtoTRAK SMX CNC
file, you may store it as ProtoTRAK SMX CNC file with the same filename and the
extension .PT4.
The drop -down menu in the Open As box shows which converters are available.
Open As types that are grayed out indicate converters that are available for
purchase.
15.9.3 Converting From the ProtoTRAK SMX CNC to a
Different Format
Files, or programs, are converted from the ProtoTRAK SMX CNC to a different format
using the Save function of Program In/Out Mode.
FIGURE 15.9.3 Use the Save As box to tell the ProtoTRAK SMX CNC what file format you want to end up with
Use the Save As box to tell the ProtoTRAK SMX CNC what kind of file you want the
current program (in the .PT4 format) to be converted into.
In Figure 15.9.3 the file name 00254 is being saved on drive A as a .mx3 file. Note
that although the program or part name as shown in the status line is BRKT005, the
file name given for converting the file conforms to the .mx3 format – fewer than
eight characters long and consisting of numbers.
15.10 ProtoTRAK and TRAK CNC Compatibility
File exchange between the ProtoTRAK SMX CNC and other ProtoTRAK and TRAK
CNC’s is possible because the ProtoTRAK SMX CNC is backward compatible. In other
words, the ProtoTRAK SMX CNC can store and retrieve other ProtoTRAK and TRAK
CNC files. The actual transfer of the files can be accomplished by using a floppy disk,
USB flash memory and/or Ethernet cable. In order to transfer files between the
ProtoTRAK SMX CNC and previous generations of ProtoTRAK and TRAK CNC, you
must have the .MX2 and .MX3 converters activated. See Section 15.9 above.
135
XYZ Machine Tools Ltd.
XYZ Turret Mill & ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
Note: Previous ProtoTRAK and TRAK CNC’s allow numeric filenames of eight (8) characters
or less, while the ProtoTRAK SMX CNC allow alphanumeric filenames (letters and numbers)
of up to twenty five (25) characters. Be sure to use only numeric filenames when storing a file
on a ProtoTRAK SMX CNC that will be retrieved by previous ProtoTRAK and TRAK CNC’s.
Before conversion, you can easily rename the file in the ProtoTRAK SMX CNC current
memory.
15.10.1 File Formats
The ProtoTRAK SMX CNC can store and retrieve the following ProtoTRAK and TRAK
CNC file formats.
Previous ProtoTRAK and TRAK CNC file formats:

15.10.2 Opening .MX2 and .MX3 Files on a ProtoTRAK SMX
CNC
Programs written on previous generation ProtoTRAK and TRAK CNC’s may be opened
and run on the ProtoTRAK SMX CNC. You will need to have the .MX2 or .MX3
converters activated (see Section 15.9 above). The ProtoTRAK SMX CNC will
automatically convert the file (.MX2 or .MX3) to a .PT4 file. The original file will
remain on the storage device unchanged and the converted file will be in current
memory. You will have to save the converted file using the procedure in Section 15.4
above in order to place in into storage.
Note that previous-generation ProtoTRAK and TRAK CNCs had a 3 and 4-sided pocket
canned cycle. This event type will be recognized and run by the SMX CNC, but
converted into a Irregular Profile event.
15.10.3 Running ProtoTRAK SMX Files on ProtoTRAK and TRAK CNC
Controls
In order to have a program written on a ProtoTRAK SMX run on a previous version
ProtoTRAK or TRAK CNC, you will need the .MX2 and .MX3 converters activated (see
section 15.9 above). Save the program as either a .MX2 or .MX3 file (depending on
the control or program you want to run).
Since there are some feature differences between the CNC’s the process will
generally yield a useable .mx2 or .mx3 program but with the following exceptions:

that after conversion, you add repeat events for
the steps and finish cut, using the technique of
overstating the size of the cutter you will use to
cut the profile.
15.11 Running G Code Files
The ProtoTRAK SMX allows you to run G Code files directly without having them converted
to the ProtoTRAK SMX programming format. You may want to do this if you have a very
large CAM file made up of small XYZ position moves, or if there is complex surface
contouring. In these cases, the ProtoTRAK SMX can handle the files more efficiently by
running the G Code directly. While running the G Code file directly does not give you the
benefit of the easy programming format of the ProtoTRAK SMX, you are not likely to be
able to use this benefit with a very large or complex file anyway.
To run the G Code file directly, open the file using OPEN AS: G Code .GCD. The
entire program will be brought into current memory. You will be able to view the tool
path when you run the program in the Run Mode, but you will not be able to edit the
program or view it in the Program Mode. In order to edit the program, use the GCode Editor in the Edit Mode (Section 10.5).

15.12 Networking
The subject of networking is extensive. This portion of the manual will give you basic
instructions for setting up a simple peer-to-peer network and some system
information useful to network administrators.
A network is simply two or more computers connected (usually by a cable) so they
may share information. Networks within a single building are called LANs for Local
Area Network.
The benefit of networking is that you can move information easily between
computers. This ease of use enables some handy functionality, for example:
1.
2.
3.
An effective file Back-up routine. File back-ups are essential if you want to retain
programs for future use. Any hard drive or floppy drive could fail. Having
program files backed up to a different location saves you from rewriting the
programs from scratch if a failure occurs.
An easy way to import CAD/CAM or DXF files from other computers.
An effective revision control. Having a single shared folder on the network
enables you to have a single location with all the latest versions of the programs.
Of course, the above functions are possible without a network by shuttling floppy
disks around. The reason to have a network is that it saves time. Once it is se t up,
you can do repetitive functions without much work. For example, if a particular job
requires you to run a CAM file that you don’t have on the ProtoTRAK SMX already,
going to the pre-arranged networked location using the Program In/Out of the SMX
gets you going right away. Without networking, someone has to make you a disk
with the file on it. Another example is program file back-ups. With networking, you
can back-up with a simple routine in the Program In/Out Mode. Without networking,
you must have a good system for managing floppy disks, including labeling, storage
and retrieving program files. You are more likely to do regular back ups if the
process is easier.
Networking can be tricky. If you do not have experience setting up a network, be
warned. Computer companies haven’t done for networks what we have done for
CNCs. Getting everything to work properly can require hours of troubleshooting,
even for experts. There are instructions below to guide you through the most basic
case of establish ing a peer-to-peer network. Beyond that, you should consult a
qualified Network Administrator.
15.12.1 Assigning a Name and Selecting a Workgroup
No matter what kind of network you establish, you must assign a name and select a
workgroup for your ProtoTRAK SMX CNC.
1.
Plug a keyboard and mouse into your ProtoTRAK SMX CNC and turn it on. Go to
the Select a Mode screen.
2.
On the keyboard press simultaneously: Ctrl + Esc. This will show the Start Menu.
3.
Select Settings from the Start menu, and then select Control Panel.

settings. See section 15.12.2
15.12.2 A Basic Peer-To-Peer Network
The following instructions will help you set up the most basic peer-to-peer network
between a ProtoTRAK SMX CNC and a computer. A peer-to-peer network simply
connects two computers of equal status together.
Hardware
1.
Obtain aDSL Cable router with DHCP services. Acceptable routers are
made by Linksys and Netgear and are available at computer stores. This type of
router will automatically assign IP addresses to your ProtoTRAK and computer,
saving you a confusing step.
2.
Obtain a sufficient quantity of twisted-pair category 5 rated Network
Cable. This looks like a telephone cable and is available at computer stores.
3.
Make sure your computer has a Network Interface Card installed. This is also
known as an Ethernet Card.
4.
Plug both the computer and the ProtoTRAK SMX into the router in the hub side of
the router. The hub side is the side with multiple cable ports. Avoid the port
that is by itself unless you really know what you are doing. The ProtoTRAK SMX
is configured to get IP addresses automatically from the router. That means that
the computers are probably connected when you turn them on and plug the

connected by looking at the lights on the front of the router. Once the
connection is made you still need to do a couple more steps before the network
is useful.

On The Desktop Computer You Want To Network.
There are differences in the process of setting up a network between Windows
98, Windows 2000, Windows™ XP and other operating systems. Fortunately,
there are just a couple of things you need to do, and the instructions for these
are already on your computer.
1.
Set your computer to automatically obtain IP addresses. For instructions on how
to do this, go to Windows™ Help and search for the topic IP Addresses. If the
lights above the cable on the router are on, you don’t have to do this.
2.
Create a Workgroup name for your computer. For instructions on how to do this,
go to Windows™ Help and search for the topic “Workgroup Names”. If there is a
workgroup name already, write it down. This is the name required in step 8,
Section 15.12.1 above.
3.
Share a part of your computer. This will allow the ProtoTRAK SMX to look into
the drives or folders you share. For instructions on how to do this, go to
Windows™ Help and search for the topic “Sharing” or “How to Share a Folder”.
In order to allow the ProtoTRAK SMX to read and write programs to this folder,
select “Full Access”.
On The ProtoTRAK SMX
1.
Press the SYS Hardkey, then the Config Net softkey. The PT4SX Network Tools
box appears. See Figure 15.12.5.
2.
Pick Map Network Drive and click OK.
Figure 15.12.5 The PT4SX Network Tools box.
3.
In the Drive box, type in “E:” You must type in both the “E” and the “:”. See
Figure 15.12.6 below. (Drive letters A through D are used by other drives.)
4.
In the Folder box, Browse for the folder on your computer that you shared
following the instructions above. When you click browse, you may have to go
through a few layers of file hierarchy before you find the folder you shared.
143
XYZ Machine Tools Ltd.
XYZ Turret Mill & ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
Figure 15.12.6 Enter E: in the Drive box and Browse for the
file you shared on your computer.
5.
6.
Click OK. The shared drive on the computer should now be accessible in the
Program In/Out Mode under drive E.
Once complete, you must now save all changes made. To do so, simply click on
the Save button at the network utility window. See figure 15.12.5
To connect other ProtoTRAKs on this simple network, repeat the process starting
with assigning a name. Each ProtoTRAK must have a unique name and use the
same workgroup.
15.12.3 General Information For Advanced Networks
The ProtoTRAK SMX CNC is a PC, but for setting up a network it is more useful to
think of it as a device such as a printer. While the ProtoTRAK has many similarities
to a desktop computer, it is different in that the use of the computer’s resources have
been optimized for running part programs and the resulting sensor feedback in real
time. In order to avoid causing a slow-down or instability in the operating system of
the control, keep the following in mind when setting up the network:
Do not use a resource-intensive networking program such as SMS. Use the
Windows™ XP utilities in the ProtoTRAK SMX instead.
Avoid loading programs that direct background tasks. Some examples are email, web browsers and anti-virus programs.
Virus Protection
As a device, ProtoTRAK CNCs are not generally susceptible to viral infections. The
part “programs” they run are non -executable text files. You can further assure
protection by avoiding e-mail programs and web browser programs loaded onto the
ProtoTRAK and by using a hub with a firewall. An anti- virus program is not necessary
since the virus risk is low, and is not recommended because the background tasks
may cause damage by interfering with ProtoTRAK real-time operation.

15.12.4 Network Tools On The ProtoTRAK SMX
There are a handful of utilities on the ProtoTRAK SMX in order to aid network set-up
for Network Administrators or experienced users. To access these utilities, press the
SYS hardkey on the ProtoTRAK SMX, then press the Config Net softkey. See Figure
15.12.5 above.
Change IP Address gives you access to the Internet Protocol Properties screen.
The default of the ProtoTRAK SMX is to obtain addresses automatically from the
DHCP server. See Figure 15.12.7.
i01135
Figure 15.12.7 TCP/IP Properties.
Add User/Password allows you to establish different users or passwords for the
ProtoTRAK SMX. This is not recommended because it means that the ProtoTRAK
SMX will need to have a keyboard plugged in each time it is turned on. This may not
be desirable in a shop environment.
Share Drive/Folder allows you to share resources on the optional USB Thumb
Drive flash memory.
Map Network Drive is covered above in Section 15.12.2 under “On the ProtoTRAK
SMX” for the basic peer-to-peer network.

CAD/CAM and Post Processors
In addition to running G-code files, the ProtoTRAK will also accept CAM files and
convert them into the ProtoTRAK events. This is a great advantage as it allows you
to have your CAD/CAM programmer send files to the machine that the machinist can
then work with in the familiar ProtoTRAK interface. The machinist can modify the
program as necessary without having to go back to the CAD/CAM programmer.
In order to be able to convert the program from a CAM system to a ProtoTRAK
program the CAM program must be two or 2½ axis. A 2½-axis program is defined
as a program where the Z axis is stationary while X and Y is moving. If you want to
run a full three-axis program, you should run a G Code, or .GCD program (see
section 15.11).
The above 2½-axis restriction does not mean that the ProtoTRAK is not capable of
running three-axis simultaneous programs written in ProtoTRAK events (as some illinformed competitors would have you believe). This restriction is a matter of
practicality. Because the ProtoTRAK allows you to program in part geometry and
therefore will figure out the tool path for you, the process of converting a three -axis
program gives the ProtoTRAK a tool position problem that it cannot resolve without a
lot more data from you. The other reason is that the output from a CAM systems for
three-axis shapes is in the form of thousands and thousands of straight -line G01
moves that would convert into the equal number of ProtoTRAK Mill events. This is
hardly a manageable program.
Instead of forcing the issue in a silly way, we give you the more elegant solution of
running GCD files. To our competitors, we respectfully point out that the thread and
helix milling canned cycles of the ProtoTRAK are obvious examples of three-axis
simultaneous interpolation. (Three-axis program fun of non -cam files is part of the
Advanced Features Option).
In order to run a CAM program, the program must be posted through a post processor that makes some adjustments to the output of the CAM software so that it
is understood by the ProtoTRAK. The ProtoTRAK uses a post-processor that is very
similar to the Fanuc 6M.
If you are not familiar with writ ing a post -processor, we recommend that you contact
your CAD/CAM supplier. We will be happy to work with him to get you the postprocessor you need.

XYZ Machine Tools Ltd.
XYZ Turret Mill & ProtoTRAK® SMX CNC Retrofit Safety, Programming, Operating & Care Manual
15.13.1 Writing a Post Processor
The following are modifications to a Fanuc 6 post -processor that are nece ssary for
writing the ProtoTRAK post -processor.
Beginning file format: The ProtoTRAK has no special requirements, it does not
need any special characters.
End of file format: the ProtoTRAK requires the % to show the end of the file.
Characters after the % will be ignored.
Beginning of an operation: the ProtoTRAK requires that the tool number, feedrate
and tool offset appear before, or on the same line, as a move command. In addition,
the ProtoTRAK requires the spindle speed be set if the Programmable E Head Option
is active. The absolute zero of the ProtoTRAK is set in a different mode and does not
need to be set at the beginning of each operation. The feedrate is modal, once it is
set, it remains the same until changed.
Lines: the line feed (or carriage return/line feed) signals the end of the line (ASCII
code hex 0A or 0D 0A). A semicolon is optional.
Coordinates : may be formatted in inch or metric. The addresses used for
specifying coordinates are X, Y, Z, I, J, K. The valid ranges are:
•
Inch: min -99.9999 to max +99.9999
•
Mm: min -999.99 to max +99.999
Rapid moves: rapid moves are generated by the ProtoTRAK automatically as part
of the definition of an event. For this reason, G0 moves are discarded unless they
specify a location other than the beginning of the following event.
Linear moves: G01 are formatted the same as rapid moves.
Arcs: Arc centers are specified by the address I, J and K for the X, Y and Z axes.
The number following the I, J and K are incrementally referenced from the startin g
point of the arc. Radius values are not allowed.
Tool Numbers and Tool Changes: the format of the tool number is from T1 to
T99. During program run, the ProtoTRAK will rapid to home for a tool change and
pause for the tool to be loaded manually and the operator to press GO.
Feed rates: the ProtoTRAK is programmed in inches (or mm) per minute using the
'F' address.
Spindle speed: If the Programmable E Head Option is active, S represents RPMs, if
not active, the S values are ignored.
File name: use the .CAM extension so the ProtoTRAK will recognize the file as a
CAM file and convert it into ProtoTRAK events when it is opened. File names may
include up to 20 alpha-numeric characters.
15.13.2
Convertible G-Codes
The following G-codes may be used in a CAM file that you want to have converted to
a ProtoTRAK program. G Codes that are not on the list below have no correspondent
operation in the ProtoTRAK events and will be ignored when the program is
converted.
If a G Code is essential to your program and you do not see it here, you can do one
of two things.
•
Convert the file from CAM to ProtoTRAK and add an event to the resulting
ProtoTRAK program.
•
Run the program as a GCD file (See Section 13.11).

Supported Addresses
CAM information is communicated through the use of ADDRESS – WORD pairs. For
example in the line “N01G0X1.Y2.” N, G, X, and Y are addresses. The other
information (01, 1, and 2) are Data Words. The line starts with the Address = N and
the data word = 01. The N address is defined as meaning “LINE NUMBER”, therefore
N01 means Line # 1, and so on.

The warranty period starts on the date of the invoice to the original purchaser from XYZ

Disclaimers of Warranties
•
This warranty is expressly in lieu of any other warranties, express or implied, including any implied
warranty of merchantability or fitness for a particular purpose, and of any other obligations or
liability on the part of XYZ (or any producing entity, if different).
•
Warranty repairs/exchanges do not cover incidental costs such as installation, labour, freight, etc.
•
XYZ is not responsible for consequential damages from use or misuse of any of its products.
•
ProtoTRAK products are precision mechanical/electromechanical measurement systems and must
be given the reasonable care that these types of instruments require.
•
Replacement of slideway wipers and covers is the responsibility of the customer. Consequently, the
warranty does not apply if chips or coolant have been allowed to enter the mechanism.
•
Accidental damage, beyond the control of XYZ, is not covered by the warranty. Thus, the warranty
does not apply if an instrument has been abused, dropped, hit, disassembled or opened.
•
Improper installation by or at the direction of the customer in such a way that the product
consequently fails, is considered to be beyond the control of the manufacturer and outside the
scope of the warranty.
