3.3.4 Back to lathe’s datum point (reference point)
There are two ways to back to datum point in this system, not only the switch for datum point, but also can set floating point, the methods as follows:
Switch for datum point:
Back to datum point operation is to feed every axis to lathe’s datum point position in turn. When the parameter of feeding axis which back to datum point is 0, the axis of coordinate detects the datum point and return to the pulsing signal of “Zero”, the data of lathe’s coordinate will be 0 automatically.
- -CNC SZGH-CNC2000TDb/TDc operation manual
Switch on the power supply of the system, release alarm and the button of emergency after the CNC is power off, the need to back to datum point to set lathe’s coordinate correctly.
Instruction:
1. The system requires for backing to the datum point every time when it is power on, the requirement can be set by No.26 parameter in axis parameter, it can be prompt or force;
2. The way and type of detecting signal can be set by No.27 parameter in axis parameter, so detect the switch of datum point is effective, also detect the Z pulsing signal of electrical motor after detecting the switch of datum point (precision higher), detect forward or reverse for Z pulsing signal of electrical motor.
3. The direction for backing to datum point can be set by No.28 parameter in axis parameter, D2 D4 correspond to X Z axis, 0 is forward, 1 is reverse.
4. The sequence of X Z back to datum point can be set by No.28 parameter in axis parameter, X is first when D8 is 0, Z is first when D8 is 1.
5. The type of the switch for datum point can be set by No.29 parameter in axis parameter, D0 D2 correspond to X Z axis,0 is always on, 1 is always off.
6. The maximum length of detecting Z pulse of electrical motor can be set by No.30 No.31 parameter in axis parameter, the value must less than the pulse of electrical motor run a cycle.
7. The shifting distance after backing to datum point can be set by No.32 No.33 parameter in axis parameter, rapid move coordinate to the value of parameter after backing to datum point.
No switch for datum point: To set floating point to make sure, turn on corresponding function of floating point by No.23 parameter in axis parameter, setting No.24 No.25 parameter to make sure X axis’ and Z axis’ floating point, the datum point of lathe.
The steps to set floating point as follows:
1. Setting the No.23 parameter in axis parameter to set the axis which is starting up floating point. For example: Turn X axis on is “00001000”. (Z axis is “00100000” turn both of them on is 00101000.)
2. Moving X axis to designated position so that set floating point.
3. Press “Parameter”, “Axis parameter” and select No.24 parameter, “Enter”, popup a dialog box of
X axis’ floating point coordinate. Import the value of setting lathe coordinate.
If it is 0, the lathe coordinate of X axis now is the datum point of X axis. The lathe backs to this position every time when backing to the datum point.
If it is 15, the current lathe coordinate of X axis is 15.000, the distance to lathe’s datum point is
15mm.
The method to set floating point of Z axis is the same as the above to set X axis.
Operation for backing to the datum point:
At the manual condition, press “ ”and select X Y Z A B axis to back to the datum point in dialog box. Set the No.28 parameter in axis parameter to “1” to make Z axis bake to the datum point first. At the absolute and relative coordinate condition, the cycle will turn to green in front when backing to the datum point successfully, defeat otherwise.
If stop in the process, press “Stop” or “Reset” to stop backing to the datum point.
Pay attention: Every time to power up the system must back to the datum point to make sure the accuracy of lathe process. The system power off unusually or in an accident, it must back to the datum point, otherwise could cause trouble.

Chapter4 Programming
CNC lathe is highly effective automatical equipment according to programmed program to process workpiece. Programming refers to process of using cnc language to describe machining track and actions based on the machining blueprint and technique requirement.
4.1 basic concepts
program segment: is a complete command line consisted of instruction segment and data segment.
Program: is a congregation of program segment by machining logic structure in order to complete the machining of workpiece.
Machine coordinate system: see fig Lathe top view.
Machine coordinate stipulates machine coordinate and direction, z axis parallels spindle, direction away from spindle is positive. X axis is vertical to spindle, the opposite of knifepoint is positive.

Absolute programming: it is confirmed coordinates data programming mode based on established absolute coordinate system. X, Z、C/Y stand for it.
Relative programming (increment programming): is the distance and direction of operation end point, compared with starting point. U, W，V stand for it.
Mixed programming: is the programming of one segment program by both absolute programming and relative programming.
Diameter programming: all X axis coordinate are presented by diameter.
Starting point: the place where the tool begins to move when program starts.
Name of program: the name of machining program.
Mode instruction: the instruction which can remain the function in the program. It works both in this program and program in the future.
In the same operation, there may be several mode instruction, such as M03 (spindle clockwise),
M04 (spindle counter clockwise), M05 (spindle stop). They are all Mode used to control spindle. The mode of same kind are categorized into one mode group. At any time it must be one of them, and there is only one of them. The original chosen mode instruction is called mode origin. In the above mode group, M05 is such a mode origin.
Suspending mode (destroying mode): is the instruction which can turn mode instruction into mode origin or destroy the mode. Such as M20 (program ending instruction), meaning the end of operation and returning to original status.
42
- -CNC SZGH-CNC2000TDb/TDc operation manual
Non mode instruction: is the instruction which has no function to store, and only works in the segment of program.

4.3 Preparation functions
4.3.1 Programming stipulation
1, multiply instruction exist in a segment simultaneously: one program line allows multiply instructions in order to reduce the lines, but the same group of instruction can not share one segment.
2, within a program segment, instruction and parameters can be arranged optionally.
Such as: G01 U10 W-30 can be written: U10 G01 W-30
3, no repeat of instruction within a program segment.
4, no irrelative parameters and operation in a segment.
5, “0” before a instruction is allowed to delete, such as: G01 G03 can be written as G1 G3.
6, the command of optional point, line start or that after tool changing instruction must be programmed by absolute coordinates.
7. Non mode command only in the in specified program line is effective,such as: G61.
8. Mode instruction is always effective before appearing the same instruction.
For example: N0000 G01 X300 F100; G01 instruction
N0001 X260; G01 instruction
N0002 G00 Z200; G00 instruction, G01 is invalid
4.3.2 Function of G Instructions
（
1）Rapid motion(G00)
Tool move to instructive position according to G00 speed in parameter。
As absolute method, use section end point coordinate to program；
As increase method, use motion distance to program。
Format：G00 X/U- Y/V- Z/W- A- B- (Mode，original)
Note：X，Y，Z，A means motion axis。The data point out motion distance and direction by absolute or increase method。
G00 move to aim point according to line way。
Moving speed is determined by paramter。
Example：from A to B.
Absolute program: G00 X20 Z0；
Relative program: G00 U－60 W－40；
47
- -CNCSZGH-2000TDb/TDc operation manual
Pay attention: The nearest calculation when using absolute coordinate of rotating axis to programming, calculation by programming when using relative coordinate;
G00 of every axis is set by parameter,the specified feeding speed with F is invalid. The speed rate of
G00 can be divided into 5%～100%, total six gears, it can be selected by the key on panel.
G00 is mode instruction, when the next instruction is G00 too, it can be omitted.G00 can be written
G0.
Pay more attention to whether the position of tool is in a safe area or not when X and Z axis both rapid moving, crashing tool in case.
（
2）Line interpolation(G01)
Used for single axis motion or 2,3,4 axis interpolation motion。
Format：G01 X/U- Y/V- Z/W- A- B- F- (Mode)
Note：X，Y，Z，A means motion axis。The data point out motion distance and direction by absolute or increase method。Motion speed is determined by F word。 The F instuction is mode.
Example：from A to B.
Absolute program: G01 X40 Z-30 F100
Relative program: G01 U20 W-30 F100
（
3）Arc interpolation(G02/G03)
G02 stands for Circular clockwise interpolation, and G03 for Circular counterclockwise interpolation. I is the 2 times of increment of X axis which starting point to center of circle (needless to double it when X axis is radius programming), K is the increment of Z axis which starting point to center of circle, and X Z are the terminal coordinates. It can be also programmed by R not IK.
Format：G02 X（U）＿ Z（W）＿ I＿ K＿ F＿；
G03 X（U）＿ Z（W）＿ I＿ K＿ F＿；
G02 X（U）＿ Z（W）＿ R＿ F＿；
G03 X（U）＿ Z（W）＿ R＿ F＿；
48
- -CNC SZGH-CNC2000TDb/TDc operation manual
Example：from A to B.
Absolute program: G02 X40 Z-20 I25 K0 ；
Relative program: G02 U20 W-20 I25 K0 ；
R program: G02 X40 Z-20 R25 ；
G02 U20 W-20 R25 .
Pay attention:
1, Processing arc workpiece usually use ball tool(arc tool) in the actual process, it must use function of tool radius compensation in programming, that's G41 G42 instruction.
2, F is the speed of the tool along the arc cutting direction.
(4) Screw thread Cutting(G32)
The system could be processed straight thread,tapper thread,straight thread continuous thread, end thread, metric thread, internal and external thread, trapezoidal thread, etc.
Straight thread: only input the direction and length of Z-axis;
Tapper thread: must input the direction and length of X-axis and Z-axis;
End thread(head face thread): only input the direction and length of X-axis;
Continuous thread: Using multi-stage instruction of G32;
49
- -CNCSZGH-2000TDb/TDc operation manual
Trapezoidal thread: offset the angle of SP in the second loop.
Variable lead thread : continuous input G32 command, enter a thread length of each program, lead of thread(F) is different , the second cycle will not begin to detect the encoder synchronization signal.
Format：G32 Z(W)_X(U)_ F(I)_ SP_
G32 is the spiral interpolation machining instruction.it is modal. X(U)_,Z(W)_is the value of end point of thread in absolutely/correspond coordinate system,Z/W is the thread length of Z axis, it cuts strait thread;X/U is the diameter thread of X axis,it cuts head face thread;
F is metric lead(pitch), the amount of displacement of the long axis of the spindle revolution.
Range is 0.1-1000 ;Unit:mm;
I is imperial lead(pitch),The number of turns of the spindle when long axis move one inch(25.4mm). Range is 0.1-99 ;Unit:teeth/inch;
Max Pitch=Lines of Spindle’s encoder/50mm.
SP(Q) is angle of tool’s cutting,Unit:degree(°),range:0-360°;Q ,Unit:0.001degree(°).Not
specified the value of SP,its value is 0.
{L is multiple thread head numbers, range is 1-999, default value is 1.}
The use of thread machining instruction must be under the condition that machine has quipped with photoelectric encoder; otherwise the system is in the status of standby. When spindle rotates clockwise, it machining plus thread in the Z axis negative direction, and left-hand thread in positive direction. The cutting feed speed F=KxN is appropriate to the machining thread, over high speed will destroy the teeth, this system requires N≤2000n/min, F≤3000mm/min.
For example:
Strait thread: N0000 G32 W-30 K1.5
; strait thread of length 30, lead 1.5
Metric thread: N0000 G32 W-30 I10.2
; thread of each inch 101/2
Head face thread: N0000 G32 U-50 K2 ; thread of length 50, lead 2
If rough or fine machining is needed, it can add fine machining rotating speed into thread fine machining instruction.
For example1:
N0000 T0101 S1200
N0010 G00 U-1
; T1 is tool for rough machining, rotating speed is 1200
; advance of tool
N0020 G32 W-30 K1.5
; rough machining
For example2:G32 cut threaded barrel:lead(pitch)=4mm,&1=3mm(Speed up the thread segments,
&1≥3mm); &2=1.5mm (Thread deceleration segment,&2≥1.5mm).Upon request, cut in twice.

Pay attention: 1. When the transmission of spindle and encoder not as 1:1, please modify the axis parameter No.412 No.413;412 means the number of teeth (requirements: less than or equal to the encoder tooth number, when it is greater than the encoder tooth number, it must match keysets of our company);
413, the encoder tooth number;
2.When processing inch thread, pitch I is non-mode,just be effective in one sentence,so every sentence should plus I in thread cycle.
3.Spindle speed S is the speed of the processing thread of pitch Fx, system requires this value should be less than 3000mm/min; The back tail speed of X axis is FxSx which is set by speed parameter No.24, system requires this value is less than 5000mm/min, such as: When processing F2, S1200,this value should be less than 20.

3) Deceleration or acceleration control in cutting thread cycle:
At the end of thread, because of the index of deceleration control,cause the distance of pitch is inhomogeneous,the higher speed of spindle the longer of inhomogeneous pitch. To reduce the error,should reduce the index of deceleration or acceleration time, but it will cause the motor stuck if match the step motor. In order to solve this problem:
● could choose Z axis according to linear acceleration or deceleration speed constant;
● could choose the X axis with the rapid speed G00 to back tail.
The relevant parameter is as follows (see the chapter of parameter):
The speed parameter
No.22 the acceleration or deceleration constant of Z axis in thread processing
No.23 the acceleration or deceleration constant of Y axis in thread processing
No.24 The backing tail speed rate of servo motor in thread cycle
No.25 The starting speed of servo motor in thread cycle
No.26 The maximum backing tail speed of servo motor in thread cycle
4)Multi thread processing function, processing function of offset angle
Using L to specify thread number directly. The SP offset angle processing.
Format: G92 X_ Z_ F_ L_ [or SP];
Note: ● Repeat L times of G92 cycle: L thread number. L is mode, after specifying,it will be effective.
● The range of L:1 ～100. Otherwise, according to the L1 to process (single thread).
● The SP (Q) specifies the cutting angle of start, unit of SP is degree, range: 0-360 °, the unit of Q is
0.001 degree. Could not use SP to specify when processing multi thread.
Such as: L03, 3 thread, continuous executing 3 times G92.The first time, begin processing at once when the spindle start rotating, the second time,after 120 degrees offset, begin cutting thread, the third time, after 240 degrees offset, begin cutting thread,
For example:
G92 X50.Z-100 F5 L5; at X50, process 5 thread.
X48.5; at X48.5, processing 5 thread.
X45; at X45, processing 5 thread.

5)Thread backs tail when fixed cycle in cutting thread
Program format:
G92 X Z F/I P;
P: volume of backing tail: the default value of P could be set by No.20 parameter in process parameter(Default when powering on).
Set unit: P1 means 0.1 pitch ; P10 means 1 pitch .
Scope: 1--225, when the set value beyond to the range is invalid.
6) Back tail at any angle function
When cutting thread without backing fuller, the system must have the function of automatical backing tail in thread processing to produce a qualified section of thread. Including the program format of backing tail in thread:
G92 X_ Z_ F_ J_ K_P_;
● J, K set the ratio of back tail X, Z. When J2 K1, X is twice faster than Z.
● P: back tail volume. Setting: 0.1 pitch. Set range: 1~255 (beyond to this range is invalid). The default value can be set by No.20 parameter in process parameter (Default when powering on).
● J, K, P are mode value.
● When executing J0 or K0 in G92, cancel any angle specify, fixed 45 degrees.The default value is 45 degrees when powering on.
● When J K are set to be negative number, or beyond to 65535,it's invalid setting. The range:
1~65535.
(12)Usage for fixed cycle
Could according to the shape of the workpiece and workblank to choose the suitable fixed cycle.As
follows:
1) Cutting cylindrical cycle G90:
2) Taper cutting cycle G90:
3) Cutting cycle of the end face G94:
60
- -CNC SZGH-CNC2000TDb/TDc operation manual
4）Taper cutting cycle of the end face G94:
Attention 1: The data X(U)、Z（W）、R are all mode value in fixed cycle of G90 G92 G94, the
front data is always effective when there is not new specified X(U)、Z（W）、R, except the screw
pitch I in inch thread process. Program instruction G90, G92, G94 has been always effective, could use the G code G00, G01 instruction to cancel.
Attention 2: The following three kinds of situation;
①
When there is just no moving instruction program behind the fixed cycle,so repeat the fixed cycle.
②
It just only use start button to run the program when using MDI.
③
In the fixed cycle, if there is M、S、T ,then use function of fixed cycle to process together. If
cancel the fixed cycle after M、S、T(Because of G00 G01), please fixed cycle again.
Example:
N10 T0101;

13）Fixed cycle of tapping (G93)
Format: G93 Z（W） F/I ;
Tapping has two kinds of method: Tracking the spindle encoder (P411=0, spindle must match encoder), spindle servo interpolation of Z axis and spindle (P405=0, P410=92, P411=4). Through the
No.404-No.411 parameter in axis parameter. The execution is as follows:
● The first is the same as G32,Z axis feed negative according to the thread cutting.
● Move to the coordinate which is specified by program, stop spindle automatically, after spindle
61
- -CNCSZGH-2000TDb/TDc operation manual stop completely, the spindle rotates negative automatically according to specification, Z axis returns to the starting position.
● Spindle stop rotating, recover to the direction of spindle rotating in front of the program.
Note: ● The cycle is the same as G90, G93 is a mode code. So G93 should specify G01 or G00 etc..
example: G93 Z-100 F5 ; tapping cycle to Z-100;
Z-101 ; tapping cycle to Z-101;
G00 X50
Tapping method of the X axis:
; G00
1)No.41 in speed parameter "mode of arc interpolation (0 means A; 8 means B)" is set to 2;
2), Enter G19 into the program segment of X tapping,enter G17 into the program segment of Z tapping, enter G18 into the next program segment after finish tapping.
For example: G93 G19 X-100 F2
G93 G17 Z-100 F2
G18 G0 X30
Pay attention:
● If execute G93 after Z moving positive, the system should execute interpolation negative first because of negative. Should set the parameter of interpolation. If the step motor is stuck , should set the smaller frequency value of interpolate compensation. Or enter the instruction to move the Z axis negative first before executing G93.
● The parameter of the spindle breaking time is affect the start rotating time after stop. Please pay attention to the setting:
Note 1: Z must move negative.
Note 2: Must start spindle rotating before executing G93.
Note 3: Require the spindle breaking time of lathe is short.
Note 4: Require the rotating speed of spindle not to high.
Note 5: For specifying inch thread when specifying I is the same as G32 G92.
Note 6: When choosing the acceleration and deceleration control, if the spindle speed change, there is some delay when making the thread change. So choose the non-speed up or down if require the accuracy. However, with a step motor, the spindle speed can not be too high, otherwise cause the stuck.

Format : G40 ; tool radius compensation cancellation
G41 ; tool radius compensation of cutter in the left of workpiece offset.
G42 ; tool radius compensation of cutter in the right of workpiece offset.
The left and right in G41, G42 are viewed from direction of cutting, tool lies in the left or right of workpiece. Tool radius is designalated by R. executing offset begins at the program line of G41,
G42. in the closed angle, system generates automatically transiting arc, allowing tool radius offset vector of last program segment transmit to that of the next program segment. Tool offset vector describes value and direction method of tool offset, its radius vector is tool radius. For arc, its direction is in radius direction. For line, its direction is vertical to the line direction.
When it transits at the closed angle arc, it will cause errors when the angle is less than 180 degree, because the transition becomes the inner closed angle transition. This system only transits outer closed angle, and remains valid only for G01, G02, G03, that is, the outer closed angle between strait line and strait line, arc and arc, strait line and arc can generate transiting arc.

Chapter 5 System installation and connection
5.1 system installation and connection
At first, users should check whether the hardware is complete, unwounded and compatible, such as: cnc system, driving power, servo motor, photoelectric encoder, electric tool carrier.
The installation of cnc system must be fastened tightly, with some spaces around to ensure the ventilation of air. Panel should be put in a place where it is not only convenient to operate and but also able to avoid hurt of heating by scrap iron.
Intense current, week current must be put separately, cnc system and driver should be possibly away from the machine intense current. In order to reduce interference, all signal cables should be kept away from AC contactor. Photoelectric encoder, limit, basic point signal are advisably not to be connected directly to cnc system through intense current box. All power cords must be earthing.
Fix all plugs with screw. Forbid to insert and extract all cables when power is on.
In installation of cnc system, panel should avoid hurting by hard and sharp materials. If the painting of other part of machine is needed, please take off cnc system to keep it clean.
To ensure there is no strong magnet and current interference, keep away from inflammable, explosive and other danger materials.
5.2 system installation dimension
This system has two types of installation, except that the installation dimension are different, the other functions are same.

Chapter 6 System’s daily maintenance and repair
In order to plenty use CNC system’s function and promote efficiency，the most important work is correctly using system，and notice system’s daily maintenance work，promote Mean Time
Between Failures MTBF。Now this system’s maintenance method is introduced as follows：
6.1 System’s maintain
6.1.1 System’s using must be under the good circumstance.
6.1.2 Operator 、programmer and repairer must be familiar with NC machining technology， and according the require of user book correctly use，do one’s best to avoid improper operation.
6.1.3 Everyday operator should clean the system’s box and panel in case for corrupt thing and sundries to damnify it.
6.1.3 When CNC system’s using time is over three month，operator should open the system box and clean inside.
6.1.4 If not using system for long time，should boot the system one time every week.
6.2 Ordinary trouble
6.2.1 System can’t boot
1） check if power is normal.
2） check if power switch is turn on.
3） check insurance.
6.2.2 No display as boot
1） Boot again or reset.
2） Check if switch power’s ＋5V、＋12V、－12V、-24V are normal.
3） Check if transformer is bad.
4） Check if LCD’s bright adjust and connection are normal.
5） Check if computer main board is normal.
6.2.3 System’s control disorganize
1） Not correct operation.
2） The switch power’s anti-jamming ability descend.
3） System’s work circumstance become bad.
6.2.4 User’s program lose
The DC battery on system main board can insure user’s program and parameter don’t lose。When system isn’t used for half year or system has been used for over two years，the battery maybe invalidate，therefore, should exchange battery.
6.2.5 Machining precision is bad
1） CNC machine’s reverse interval would change after using for a period of time，it needs to revise on time.
2） Best to revise base point before machining in order to insure the start point’s precision.
3） Machining speed and cutting depth is improper.
4） Machine connector’s prick melt falls off.
5） Tool isn’t tightened.
6） Piece clamp isn’t good.
7） Tool’s giving up isn’t equality because piece’s dimension isn’t uniformity.
