Hurco is committed to designing reliable, easy-to-operate gauging systems
which promote greater productivity. This system will provide a modern,
efficient method of meeting metal forming needs. To prevent serious
bodily injury, always observe the safety precautions listed in this manual
when installing, operating, and servicing the Autobend System.
These and other safety precautions are discussed in the American National
Standards Institute’s “Standard for Machine Tools - Power Press Brakes Safety Requirements for Construction, Care, and Use” (ANSI B11.3). The
press brake operator’s responsibility regarding his or her own safety, the
safety of assigned helpers, and the safety of others affected by the press
brake operator’s acts is explained in this ANSI publication which is
available from:
American National Standards Institute
1430 Broadway
New York, NY 10018
These and other safety precautions are discussed in the European A type
standards EN292 parts 1 and 2, “The Supply of Machinery (Safety)
Regulations 1992.” No. 3073 and “The Supply of Machinery (Safety
Amendment) Regulations 1994.” No. 2063. These and other publications
are available from:
HMSO bookshops and accredited agents or HMSO publications
centre (tel: 0171 873 9090, fax: 0171 873 8200) or DTI Business in
Europe Hotline on (01779) 444888.
Refer additional questions or concerns to the local Health and Safety
Officer.
In preparing these instructions, we have attempted to recommend the most
effective methods and cautions to warn against actions that could cause
personal injury or make the equipment unsafe. It is important to
understand that Hurco cannot anticipate or list all conceivable methods
and warn of all possible hazards. In the interest of promoting safety, Hurco
advises that service personnel and operators should always make sure that
personal safety, the safety of the operator, and the safe operation of the
machine will not be adversely affected by their actions. Review the list of
safety precautions before attempting to service or operate the system. Also
review the manuals furnished by your press brake manufacturer for
additional safety information and procedures that must be observed.
Please read all information for safe, efficient use of the Hurco Autobend 6

Safety Precautions
It is important to follow all of Hurco and the press brake manufacturer’s
safety precautions to avoid personal injury, damage to the machine, and
unproductive downtime. Installers must also follow the safety regulations
of their shops.
This section is included to address the safety hazards normally
encountered with the intended use and the foreseeable misuse of the AB6.
This product is intended to be used by trained operators who create metal
bending programs either on the control or an off-line system and then run
the programs on the AB6. While running the AB6, the operators must use
their experience and training to make any necessary adjustments and
improve the efficiency of their programs.
Warning
Errors in setup or programming can damage the press
brake and cause severe personal injury. Hurco’s AB6
does not reduce or eliminate the need for its users to
follow the safety and operating instructions the press
brake manufacturer provides. Do not ignore safety
policies and safeguarding circuits of the press brake’s
controls.
This safety section describes common problems seen by Hurco Service
representatives with suggestions for avoiding or dealing with the problems
in a safe manner. However, this information is not an exhaustive
description of all of the possible misuses of the AB6 nor is it a substitute
for operator training, skill, and good judgment. Hurco does not accept any
liability for operator error.

Revision D
Hurco
System Basics
Owner’s Responsibilities
The AB6 owner has several responsibilities regarding safety. First, the
owner must read this section of the manual and implement the safety
requirements described. Then the owner must be certain that the operators
in the shop are properly trained and are using the AB6 as it is intended to
be used. The owner must be certain that the operator assigned to run the
AB6 is trained by Hurco.
If the Hurco trained operator leaves the shop, the owner is responsible for
providing training for the new operator assigned to run the AB6. Call the
nearest Hurco facility for information about on-site training or other
special training opportunities.
The owner must also establish proper procedures to prevent fires and
provide approved fire extinguishers to put out small fires. Of course, large
fires must be extinguished by professional fire fighters. As a safety
precaution, many shops have regular fire drills so that all employees know
their responsibilities during an emergency situation.
Machine Modification
The AB6 was designed to meet a wide range of customer needs. If the
owner feels that the AB6 needs to be modified in any way to meet the
special needs of the shop, Hurco recommends that the owner call Hurco
Technical Support or an authorized Hurco distributor for modification
assistance and a written authorization to proceed. Contact the press brake
manufacturer for information about press brake modification.
If the owner modifies the AB6 in any way without Hurco’s assistance and
a written authorization, the warranty becomes invalid. In addition, such
unauthorized modifications may cause safety hazards that may injure the
operator and damage the AB6. The owner is fully responsible for any
accidents resulting from unauthorized modifications.
Autobend 6
September, 1999
1-7
Programming and Operations Manual
Hardware and Software
If the owner or an operator modifies the hardware or software by
removing, altering, disabling, or tampering with any safety circuit, safety
switch, or any safety operation and then continues to operate the AB6 with
those modifications, such operation is extremely hazardous, a foreseeable
misuse, and voids the Hurco warranty. If the owner or an operator finds
that such modifications have been made, that person must immediately
switch off the AB6 and prevent its use until it has been repaired. The
owner must then contact a Hurco service representative for assistance in
restoring the AB6 to safe operation.
Important
In many locales, machine hardware or software modification to
override safety protections and continued operation of such a
modified machine is illegal and punishable with a fine and/or
imprisonment.
Installation
The owner is responsible for proper site preparation before the AB6 is
installed as described in this manual. A Hurco Field Service Engineer or
an authorized representative must install the AB6 in the prepared location.
This location must not subject the AB6 to uncontrolled cabinet
temperatures or unfavorable work environment conditions that could cause
electronic component failure.
If the owner decides later to move the press brake from its installed
location, and if it is necessary to remove the control console from the press
brake, Hurco recommends that the owner call Hurco for assistance. Hurco
recommends that the owner use a competent rigger with the necessary
equipment to move the press brake to the desired location.

System Basics
Maintenance
The owner must be certain that the shop’s maintenance personnel are
trained.
Warning
This AB6 must not be serviced, repaired, or maintained
by unqualified or untrained personnel.
If at any time the operator or owner determines that the electrical cabinet
must be opened, the power must be shut off to the AB6 and the press brake
before the doors are opened. The only exception to this rule is when the
AB6 or press brake is being serviced for electrical problems. Under those
circumstances, Hurco Field Service should direct the person performing
the work.

Safety Signs
Safety-related signs pertaining to the AB6 are affixed to appropriate
system components. A warning sign appears on the safety decals that must
be affixed to specific areas on the Autobend components. (See the
Installation manual for directions for affixing these decals.) The warning
signs alert operators of the possibility of personal injury and damage to the
AB6 and press brake if they do not follow the described procedure.

System Basics
Operators’ Responsibilities
To avoid serious personal injury, damage to the AB6, and unproductive
downtime, the operator must pay careful attention to safety precautions
and proper maintenance of the AB6. Press brake operation is often a
dangerous task, so operators must stay alert and be aware of potential
hazards. Operators must also follow the safety regulations of their shops.
Training
All operators must be trained in order to operate an AB6. The operators
who are going to run the press brake must be trained by Hurco or an
authorized representative. Before attempting to run the AB6, the operator
should study this manual and become familiar with the functions and
safety features.
While studying the manual, the operator should make special note of the
caution and warning messages in the manuals and all warning and
instruction plates/decals on the AB6 and the press brake.
Clothing and Other Apparel
Operators should always wear eye protection and safety shoes while in the
work area. Safety glasses with side shields are recommended. The operator
should not wear items such as loose-fitting clothing, watches, necklaces,
rings, and neckties that could become caught in the moving parts of the
AB6 and press brake.
Personal Care
Operators must follow established working practices and personal hygiene
standards. As part of this effort, they must avoid frequent or prolonged
skin contact with fluids and oils on the sheet metal. Some operators wear
gloves or use a special hand cream to protect their hands from these
chemicals. If operators get chemicals on their hands, they must wash their
hands immediately upon leaving the AB6 and press brake and before
taking a break. They must also change clothing that has become
contaminated with fluids and oils.
For complete information about handling industrial chemicals used in
machining, refer to the international Control of Substances Hazardous to
Health (COSHH) materials from the chemical suppliers.

System Basics
System Operation (continued)
•
Never operate a disassembled system.
•
Disconnect the external power source before attempting to
connect or make adjustments within the power supply box
or the Autobend power supply cabinet. Only qualified
personnel should service this equipment.
•
Before operating the system be sure that installers or
operators will not be struck by the rapid movement of the
gauge bar. Also make certain that nothing interferes with the
gauge movement in either direction.
Note
This list does not include all of the possible hazards regarding the
AB6 and the press brake.
Part Dimensions and Fixturing
Operators should never bend a part on the gauging system that is larger
than the working surface of the press brake or that juts out on any side
beyond the edges of the press brake. If a part requires a range that is
greater than the guarding allows, the work must be performed on another
system having the necessary work volume capability.
Operators must follow procedures for referencing the bending material
before starting the AB6. Remember that loose objects, such as wrenches
and chuck keys, can become flying projectiles if not removed from the
gauge bar before the AB6 is started. Operators should also be aware of
protruding machine members (such as hoses, piping, or ductwork) when
working around the AB6 and the press brake.
Travel Limits
Safety limit switches provided for each system must not be removed or
bypassed in order to obtain more travel or take short cuts. Serious damage
to the AB6 and personal injury to the operator may result from such
actions. It is also dangerous to bend a part that requires operation outside
the limits of the AB6. A larger press brake should be used for such a part.

Programming and Operations Manual
Part Bending
Operators should always know the locations of the Stop key on the press
brake and AB6 control. The operator must be very careful when working
in the area of the gauge. To prevent injury, the gauge should be completely
stopped before the operator attempts to make adjustments to a work piece
or the gauging surface.
Warning
When running programs, operators should always
follow these rules:
•
Never press the Run key without knowing exactly what the
AB6 and press brake will do!
•
Never start the AB6 when the back gauge is in contact with
the work piece.
•
Never stand in the rear inside area between the back of the
press brake bed and the gauge bar while the gauge is
moving.
•
Never leave the AB6 or the press brake unattended.
The operator must work within reach of the Stop keys and must be able to
observe the operation of the gauge. If the operator is running a program
and cannot reach a Stop key nor observe the gauge, that is considered
unattended operation and is viewed as a foreseeable misuse of the AB6.

System Basics
Subsystem Failure
Maintenance personnel and trained operators need to understand the
maintenance requirements and possible problems associated with the press
brake subsystems. They can become familiar with the subsystem
maintenance requirements by studying the press brake’s maintenance
manual.
Electrical Systems
Clean electrical AC power source, as defined in the ANSI/NFPA 79
standard, is essential to the successful operation and continued reliability
of the AB6. Therefore, the gauging system must be properly connected to
its power source as described in detail in this manual. The AB6 must be
attached to a dedicated, fused, and isolated line with incoming power that
matches the specified, factory-wired, power cabinet voltages, and current
requirements of the AB6 system.
Warning
If the AB6 is not properly connected to its power
source, there may be electrical noise and fluctuations
with the power source that will affect safety,
performance, and the warranty. In addition, brownout
conditions and surges may occur in the shop, and the
AB6 electrical components may fail and require
replacement.

Electrical Safety Guidelines
Follow these electrical safety guidelines before operating the AB6:
1-16
1.
Provide a clean source of electrical power with a separate
dedicated incoming power line (hot, neutral, and ground
wire).
2.
Ensure that this source of electrical power is of proper
voltage and is free of electrical sags, surges, spikes, and
noise. This source must be free of inductive loads that might
cause high-frequency electrical noise.
3.
Prevent an unwanted ground loop. The electrical control
systems are interconnected to terminate at the central point
ground terminal located inside the AB6 power cabinet. This
single point ground must be connected to the ground circuit
of the electrical power source so that it provides only one
conducting path (between the AB6 power cabinet and the
power cord).
4.
Route all AB6 cables to prevent close contact (6" - 10", 150
mm. - 250 mm.) with any press brake control, voltage line,
motor, or other noise-generating devices.
5.
Attach all system cables properly to the press brake’s frame.
Loop cables with excessive length. Use the extra large tie
wraps and 3/8" self-tapping screws provided to attach the
cables to the frame.

Procedures for Handling Printed Circuit Boards
Static charges are present at all times and in all environments. Damage to
sensitive electronics occurs at lower voltage levels than people can sense.
Static damage may cause total failure or degrade the circuits’ performance
and can eventually lead to intermittent or total failure. Prevent component
damage by discharging static electricity to a ground. Follow the procedures
below.
Before touching, adjusting, or removing a printed circuit board (PCB),
wear a wrist strap grounded to the cabinet or enclosure ground point. If a
grounding wrist strap is not available, touch a grounded point within the
enclosure each time before touching a PCB or electronic assembly. An
example of a grounding point is the metal cabinet’s screws.
Caution
Limit the direct handling of the PCB to reduce the chance of damage.
Keep the PCB in a protective bag until it is installed. Use static
handling procedures before opening the bag and removing the circuit
board. Return all replaced PCBs to the static protective bag.

Fire Prevention and Fighting
There are some obvious causes of fires that should be avoided in all shops:
•
Storing or handling flammable materials near heat sources.
•
Failing to keep the work area clear of debris such as shop
clothes, cartons, and other shop supplies that could catch
fire.
If a fire does occur, the operator must press the Stop key on the control and
on the press brake and activate the factory’s fire alarm system to evacuate
personnel who are not directly involved with extinguishing a small fire.
Shop personnel may be able to put out small fires using extinguishers
approved for the conditions in their shops. However, if it is clear the fire is
uncontrolled or too large for the shop extinguishers, professional fire
fighters must be called and all shop personnel evacuated.
If a fire has occurred and the shop personnel have extinguished it, it may
still be wise to contact the fire department or fire prevention authorities for
advice to be certain the fire has been completely extinguished and to help
prevent future fires. Fire extinguishers should be tested for proper
operation at least three times a year by a trained and certified inspector.

Chapter 2
Programming and Operations
The Autobend 6 (AB6) is a one or two axis control system capable of
operating a back gauge (X axis) and the press brake’s ram position
(optional Y axis). The optional Y-Hydraulic axis controls the ram’s open
height and speed change. The memory is capable of storing 150 jobs and
600 bends.
This chapter describes the control functions, the programming process,
referencing and calibration procedures.
Display and Keypad Groups
The AB6 control contains a display group at the top of the control where
programming entries or default values appear. There are also programming
keys with dedicated LEDs (light emitting diodes).
Values for Gauge, Ram, Job and Bend appear in the displays. Single axis
Job and Bend programming keys are located below the Gauge display, and
two-axis Job and Bend programming keys are located below the Ram
display.
The Data Entry keys are grouped together in the lower right-hand corner of
the control. Use them to select tasks, scan job and bend lists, perform
calculations, select special functions, and input numbers. Within this
group of keys are the yellow Job, Bend, and New Bend programming keys.
The keys in the Run group are the operation keys. They are located in the
bottom center portion of the control. Use them to select Auto or Single
Run mode and to jog the selected axis.
Use the Master Save function to back up programs on a non-volatile Flash
EPROM. This function saves all information in case of a battery backup
failure during a power outage. Refer to the “Initial System Setup” section
later in this chapter for these procedures.

Selecting the Gauging Surface
The Autobend gauge bar provides various methods of referencing the
material to be formed. For best results do not place material directly
against the front edge or face of the gauge bar. This surface should be used
to hold the flip fingers and gauge blocks suited to this task. Ideally using
two stops per bend is recommended since tooling centerlines and material
edges are typically not straight.
Figure 2-1.
Autobend 6
Flip Fingers and Gauge Block
September, 1999
2-29
Programming and Operations Manual
Flip Fingers
Flip fingers permit closer gauge positioning to the tooling. The fingers’
tilting action allows reverse bending, with the length of the reverse bend
dependent on the type of part to be formed.
Fingers can be manufactured by customers to suit their individual forming
needs. For the most accurate results, always reference the flip fingers prior
to using them after changing the tooling setup. Refer to the “Referencing
the Gauging Surface” section that follows.
Install the flip fingers at any location along the gauge bar to best suit the
requirements of the part. These fingers allow approximately 0.090" of
horizontal micro-adjustment for close-tolerance forming. Fingers rotate in
90° increments for narrow or wide target area selection. Each finger tilts
on a leveling adjustment screw at the front bottom of the body. The
locking screw at the end of the flip finger assembly is used to lock it in
place along the gauge bar.
When two flip fingers are used, both must be set to the same length, as
measured from the back of the body to the tip of the finger. Otherwise, the
parts will not have equal flange lengths on both ends.
Gauge Blocks
Gauge blocks provide a large target area suited for work involving largescale parts and long flanges.
Install gauge blocks at any location along the gauge bar to best suit the
requirements of the part. The locking screw at the end of the gauge block
is used to lock the block in place on the gauge bar. For the most accurate
results, always reference the gauge blocks prior to using them after
changing the tooling setup. Refer to the “Referencing the Gauging
Surface” section that follows.
Warning
Ensure that the carriage arrestor bars are correctly set
on the gauge(s) to prevent any part of the gauge bar,
finger(s) or block(s) from contacting the tooling in an
unsafe manner. All adjustments should be made from
the rear of the press brake. Do not reach across the
tooling or in through the bed and ram.

Revision D
Hurco
Programming and Operations
Referencing the Gauging Surface
Prior to forming parts, the gauging surface must be referenced to the
forming tools. The programmed dimension is the distance from the
gauging surface to the punch centerline. This centerline changes for each
set of tooling.
Two zero reference bars are provided with each Autobend to provide a
quick and controlled method of squaring the gauge bar. Each zero
reference bar has a 90° “V” notch in the center and a machined edge on
one end. The distance from the center of the “V” notch to the machined
edge is 5" (127 mm).
Warning
Do not use the reference bars if the rubber pad is
damaged or missing. This pad is a safety feature to
reduce the possibility of breakage from slight overpressure. The pads will not prevent the bars from
breaking in the event of severe over-pressure from the
press brake.

8.
Adjust the gauge bar’s height so the gauging surface is
aligned with the reference bars.
9.
Push the vertical supports forward so the gauging surface is
flush against the zero reference bars. For the most accurate
results, use a 0.002" feeler gauge to verify that the gauge
surface is flush with the machined edge of the zero reference
bars.

Y-Hydraulic Calibration
Before calibrating a downacting hydraulic press brake in either Run or
Jog/Teach mode, be familiar with these points:
Important
Manually position the ram with the press brake’s foot pedal or palm
buttons.
The press brake must be set at jog settings for calibration.
The ram returns to top on auto return press brakes during Die Top
and Die Bottom if not set properly.
Press the Stop key to abort the calibration sequence.
Caution
The Speed Change relay (K6) is held energized to hold the ram at

Optional RS-232-C Serial Port
The RS-232-C serial port provides uploading or downloading of the entire
memory block between the AB6 control and a personal computer. For best
results, be familiar with the following information concerning location,
connector types, cables, and pins before operating the system with this
option.
Port Location
RS-232-C connection to the AB6 is located on the power cabinet. Connect
the port to a computer to download or upload files.
Connector Types
Since the communications industry standard for connectors has changed
over the years, Hurco has adapted its controls to incorporate these changes.
The RS-232-C serial port on the Hurco control uses a 9-pin D-type
connector.
A 9-pin D-type connector (DB-9) is illustrated in the figure that follows
this section. Refer to the table on the following page for additional
information pertaining to DB-9 serial port connections.
Note
While the signals listed in the table on the following page conform to
the RS-232-C standard, it should be noted that not all standard RS232-C signals are available at this port. Some peripheral devices may
have provisions for RS-232-C control signals not available at the
ports described here. However, such devices can usually be adapted
to these ports. In some cases, it may be necessary to add jumpers to
the connector for the peripheral device.
