Chapter 1: Safety

1.1 General Safety Notes

CAUTION: Only authorized and trained personnel may operate this equipment.

You must always act in accordance with the Operator's manual, safety
decals, safety procedures, and instructions for safe machine
operation. Untrained personnel present a hazard to themselves and
the machine.

IMPORTANT: Do not operate this machine until you have read all warnings, cautions,

and instructions.

CAUTION: The sample programs in this manual have been tested for accuracy,

but they are for illustrative purposes only. The programs do not define
tools, offsets, or materials. They do not describe workholding or other
fixturing. If you choose to run a sample program on your machine, do
so in Graphics mode. Always follow safe machining practices when
you run an unfamiliar program.

Safety

All CNC machines present hazards from rotating cutting tools, belts and pulleys, high
voltage electricity, noise, and compressed air. When you use CNC machines and their
components, you must always follow basic safety precautions to reduce the risk of personal
injury and mechanical damage.

The work area must be adequately illuminated to allow clear view and safe operation of the
machine. This includes the operator work area and all areas of the machine that might be
accessed during maintenance or cleaning. Adequate illumination is the responsibility of the
user.

Cutting tools, workholding, workpiece and coolant are beyond the scope and control of
Haas Automation, Inc. Each of these potential hazards associated with it (sharp edges,
heavy lifting considerations, chemical composition, etc) and it is the responsibility of the
user to take appropriate action (PPE, training, etc).

Cleaning of the machine is required during normal use and prior to maintenance or repair.
Optional equipment is available to aid cleaning such as washdown hoses, chip conveyors
and chip augers. Safe use of this equipment requires training and might require appropriate
PPE and is the responsibility of the user.

This operator’s manual is intended as a reference guide and is not to be the sole source of
training. Complete operator training is available from the authorized Haas distributor.

General Safety Notes

1.1.1 Summary of Types of Operation for Haas Automation

Machine Tools

Haas CNC Mills are intended for cutting and shaping of metals and other hard materials.
They are general purpose in nature and a list of all of those materials and types of cutting
would never be complete. Almost all cutting and shaping is performed by a rotating tool
mounted in a spindle. Rotation of the mill is not required. Some cutting operations require
liquid coolant. That coolant is also an option depending on the type of cutting.

Operations of Haas Mills are separated into three areas. They are: Operations,
Maintenance, and Service. Operations and Maintenance are intended to be performed by
a trained and qualified machine operator. This Operator's Manual contains some of the
information necessary to operate the machine. All other machine operations are to be
considered Service. Service is only to be performed by specially trained service personnel.

Operation of this machine consists of the following:

1. Machine Setup

• Machine setup is done to initially set up the tools, offsets, and fixtures required
to perform a repetitive function that later is called machine operation. Some
machine setup functions can be done with the door open but are limited to
“hold to run”.

2. Machine operating in Automatic Mode

• Automatic operation is initiated with Cycle-Start and can only be done with the
doors closed.

3. Operator loading and unloading of materials (parts)

• Parts loading and unloading is what precedes and follows an automatic
operation. This must be done with the doors open and all machine automatic
motion is stopped when the door is open.

4. Operator loading and unloading of cutting tools

• Tool loading and unloading is done less often than setup. It is often required
when a tool has become worn and must be replaced.

Maintenance only consists of the following:

1. Adding and maintaining condition of coolant

• Adding coolant and maintaining coolant concentration is required at regular
intervals. This is a normal operator function and is either done from a safe
location outside of the work enclosure or with the doors open and the machine
stopped.

2

2. Adding lubricants

• Adding lubricants for spindle and axes is required at regular intervals. These
are often months or years in length. This is a normal operator function and is
always done from a safe location outside of the work enclosure.

3. Cleaning chips out of the machine

• Cleaning out of chips is required at intervals dictated by the type of machining
performed. This is a normal operator function. It is performed with the doors
open and all of the machine operation is stopped.

Service only consists of the following:

1. Repairing of a machine that is not operating correctly

• Any machine that is not operating correctly requires service by factory trained
personnel. This is never an operator function. It is not considered
maintenance. Installation and service instructions are provided separately
from the Operator’s Manual.

2. Machine moving, unpacking, and installation

• Haas machines are shipped to a user’s location almost ready to operate. They
still require a trained service person to complete the installation. Installation
and service instructions are provided separately from the Operator’s Manual.

Safety

3. Machine packing

• Machine packing for shipment requires the same packing material supplied by
Haas in the original shipment. Packing requires a trained service person to
complete the installation. Shipping instructions are provided separately from
the Operator’s Manual.

4. Decommission, dismantle and disposal

• Machine is not expected to be disassembled for shipment; it can be moved in
its entirety in the same manner in which it was installed. Machine can be
returned to the manufacturer’s distributor for disposal; manufacturer accepts
any/all components for recycling per Directive 2002/96/EC.

5. End-of-life disposal

• End-of-life disposal must conform to the laws and regulations in the region the
machine is located. This is a jointly the responsibility of the owner and seller of
the machine. The risk analysis does not address this phase.

General Safety Notes

1.1.2 Read Before Operating

DANGER: Do not enter the machining area any time the machine is in motion, or

at any time that machine motion is possible. Severe injury or death
may result. Motion is possible when the power is on and the machine
is not in [EMERGENCY STOP].

Basic safety:

• This machine can cause severe bodily injury.

• This machine is automatically controlled and may start at any time.

• Consult your local safety codes and regulations before you operate the machine.
Contact your dealer if you have questions about safety issues.

• It is the machine owner’s responsibility to make sure that everyone who is involved
in installing and operating the machine is fully acquainted with the operation and
safety instructions provided with the machine, BEFORE they work with the machine.
The ultimate responsibility for safety rests with the machine owner and the individuals
who work with the machine.

• Use appropriate eye and ear protection when you operate the machine.

• Use appropriate gloves to remove processed material and to clean the machine.

• Replace windows immediately if they are damaged or severely scratched.

• Keep the side windows locked during operation (if available).

Electrical safety:

• The electrical power must meet the required specifications. Attempting to run the
machine from any other source can cause severe damage and will void the warranty.

• The electrical panel should be closed and the key and latches on the control cabinet
should be secured at all times, except during installation and service. At those times,
only qualified electricians should have access to the panel. When the main circuit
breaker is on, there is high voltage throughout the electrical panel (including the
circuit boards and logic circuits) and some components operate at high
temperatures; therefore, extreme caution is required. Once the machine is installed,
the control cabinet must be locked, with the key available only to qualified service
personnel.

• Do not reset a circuit breaker until the reason for the fault is investigated and
understood. Only Haas-trained service personnel should troubleshoot and repair
Haas equipment.

• Do not press [POWER UP] on the control pendant before the machine is fully
installed.

4

Safety

Operation Safety:

• Do not operate the machine unless the doors are closed and the door interlocks are
functioning correctly.

• Check for damaged parts and tools before you operate the machine. Any part or tool
that is damaged should be properly repaired or replaced by authorized personnel. Do
not operate the machine if any component does not appear to be functioning
correctly.

• Rotating cutting tools can cause severe injury. When a program runs, the mill table
and spindle head can move rapidly at any time.

• Improperly clamped parts machined at high speeds/feeds may be ejected and
puncture the enclosure. It is not safe to machine oversized or marginally clamped
parts.

Release of person trapped in the machine:

• No person should ever be located inside the machine during operation.

• In the unlikely event that a person is trapped inside the machine the emergency stop
button should be immediately be depressed and the person removed.

• If the person is pinched or entangled the machine should be powered off; then the
machine axes can be moved by use of a large external force in the direction required
to free the person.

Recover from a jam or blockage:

• Of the chip conveyor - Follow the cleaning instructions on the Haas Resource Center
(diy.haascnc.com). If necessary, close the doors and reverse the conveyor so the
jammed part or material is accessible, and remove. Use lifting equipment or get
assistance for lifting heavy and awkward parts.

• Of a tool and material/part - Close the doors, press [RESET] to clear and displayed
alarms. Jog the axis so the tool and material are clear.

• Of the Automatic Tool Changer/tool and spindle - Press [RECOVER] and follow the
on-screen instructions.

• If the alarms do not reset or you are unable to clear a blockage, contact your Haas
Factory Outlet (HFO) for assistance.

Follow these guidelines when you work with the machine:

• Normal operation - Keep the door closed and guards in place (for non-enclosed
machines) while the machine operates.

• Part loading and unloading – An operator opens the door, completes the task, closes
the door, and then presses [CYCLE START] (starting automatic motion).

• Machining job set-up – When set-up is complete, turn the set-up key to lock out
set-mode and remove the key.

• Maintenance / Machine Cleaner– Press [EMERGENCY STOP] or [POWER OFF] on
the machine before you enter the enclosure.

General Safety Notes

Periodic maintenance of machine safety features:

• Inspect door interlock mechanism for proper fit and function.

• Inspect safety windows and enclosure for damage or leaks.

• Verify all enclosure panels are in place.

Door Safety Interlock maintenance:

• Inspect the door interlock, verify the door interlock key is not bent, misaligned, and
that all fasteners are installed.

• Inspect the door interlock itself for any signs of obstruction or misalignment.

• Immediately replace an components of the Door Safety Interlock system that do not
meet this criteria.

Door Safety Interlock testing:

• With the machine in run mode, close the machine door, run the spindle at 100 RPM,
pull the door and verify the door does not open.

Machine Enclosure and Safety Glass maintenance and testing:

Routine Maintenance:

• Visually inspect the enclosure and safety glass for any signs of distortion, breakage
or other damage.

• Replace the Lexan windows after 7 years or if they are damaged or severely
scratched.

• Keep all safety glass and machine windows clean to allow proper viewing of the
machine during operations.

• A daily visual inspection of the machine enclosure to verify all panels are in place
should be performed.

Testing of machine enclosure:

• No testing of the machine enclosure is necessary.

1.1.3 Machine Environmental Limits

This table list the environmental limits for safe operation:

T1.1: Environmental Limits (Indoor Use Only)

Minimum Maximum

Operating Temperature 41 °F (5.0 °C) 122 °F (50.0 °C)

Storage Temperature -4 °F (-20.0 °C) 158 °F (70.0 °C)

Ambient Humidity 20% relative, non-condensing 90% relative, non-condensing

Altitude Sea Level 6,000 ft. (1,829 m)

CAUTION: Do not operate the machine in explosive atmospheres (explosive

vapors and/ or particulate matter).

Safety

1.1.4 Machine Noise Limits

CAUTION: Take precautions to prevent hearing damage from machine/machining

noise. Wear ear protection, change your application (tooling, spindle
speed, axis speed, fixturing, programmed path) to reduce noise, or
restrict access to machine area during cutting.

Typical noise levels at the operator’s position during normal operation are as follows:

• A-Weighted sound pressure level measurements will be 69.4dB or lower.

• C-Weighted instantaneous sound pressure levels will be 78.0dB or lower.

• LwA (sound power level A-weighted) will be 75.0dB or lower.

NOTE: Actual noise levels while cutting material are greatly affected by the

user’s choice of material, cutting tools, speeds and feeds, workholding
and other factors. These factors are application specific and are
controlled by the user, not Haas Automation Inc.

Unattended Operation

1.2 Unattended Operation

Fully enclosed Haas CNC machines are designed to operate unattended; however, your
machining process may not be safe to operate unmonitored.

As it is the shop owner’s responsibility to set up the machine safely and use best practice
machining techniques, it is also the owner’s responsibility to manage the progress of these
methods. You must monitor your machining process to prevent damage, injury, or loss of
life if a hazardous condition occurs.

For example, if there is the risk of fire due to the material machined, then you must install
an appropriate fire suppression system to reduce the risk of harm to personnel, equipment,
and the building. Contact a specialist to install monitoring tools before machines are
allowed to run unattended.

It is especially important to select monitoring equipment that can immediately detect a
problem and perform an appropriate action without human intervention.

1.3 Setup Mode

All Haas CNC machines are equipped with locks on the operator doors and a key switch
on the side of the control pendant to lock and unlock setup mode. Generally, setup mode
status (locked or unlocked) affects how the machine operates when the doors are opened.

Setup mode should be locked out (the keyswitch in the vertical, locked position) at most
times. In locked mode, the enclosure doors are locked closed during CNC program
execution, spindle rotation or axis movement. The doors automatically unlock when the
machine is not in cycle. Many machine functions are unavailable with the door open.

When unlocked, setup mode allows a skilled machinist more access to the machine to set
up jobs. In this mode, machine behavior is dependent on whether the doors are opened or
closed. Opening the doors when the machine is in cycle stops motion and reduces spindle
speed. The machine allows several functions in setup mode with the doors opened, usually
at reduced speed. The following charts summarize the modes and allowed functions.

Machines with software version 100.17.000.1016 or higher have Parameter 2083, Setup
Mode Safety Type, that affects the machine’s Setup mode. When Parameter 2083 is set to
Normal, the machine Setup and Run modes behave as outlined in the table that follows.
When Parameter 2083 is set to Strict, both the Setup and Run modes adhere to the Run
mode behaviors. Contact your local Haas Factory Outlet to set Parameter 2083 to your
desired setting on your machine.

DANGER: Do not attempt to override safety features. Doing so makes the

machine unsafe and voids the warranty.

Modifications to the Machine

1.3.2 Robot Cells

A machine in a robot cell is allowed to run a program while the door is open, regardless of
the position of the Run-Setup key. While the door is open, the spindle speed is limited to
the lower of the factory RPM limit or Setting 292, Door Open Spindle Speed Limit. If the
door is opened while the spindle RPM is above the limit, the spindle will decelerate to the
limit RPM. Closing the door removes the limit and the programmed RPM is restored.

This open-door condition is allowed only while a robot communicates with the CNC
machine. Typically, an interface between the robot and the CNC machine addresses the
safety of both machines.

Robot cell setup is beyond the scope of this manual. Work with a robot-cell integrator and
your HFO to correctly set up a safe robot cell.

1.3.3 Mist Extraction / Enclosure Evacuation

The Mill products have a provision installed that will allow for a mist extractor to be attached
to the machine (except CM & GR models). There is also an optional enclosure exhaust
system available that helps keep the mist out of the machine enclosure.

It is entirely up to the owner/operator to determine if and what type of mist extractor is best
suited for the application.

The owner/operator assumes all responsibility for the installation of the mist extraction
system.

1.4 Modifications to the Machine

Haas Automation, Inc. is not responsible for damage caused by modifications you make to
your Haas machine(s) with parts or kits not manufactured or sold by Haas Automation, Inc.
The use of such parts or kits may void your warranty.

Some parts or kits manufactured or sold by Haas Automation, Inc. are considered
user-installable. If you choose to install these parts or kits yourself, be sure to completely
read the accompanying installation instructions. Make sure you understand the procedure,
and how to do it safely, before you begin. If you have any doubts about your ability to
complete the procedure, contact your Haas Factory Outlet (HFO) for assistance.

1.5 Improper Coolants

Coolant is an important part of many machining operations. When it is correctly used and
maintained, coolant can improve part finish, lengthen tool life, and protect machine
components from rust and other damage. Improper coolants, however, can cause
significant damage to your machine.

Such damage can void your warranty, but it can also introduce hazardous conditions to
your shop. For example, coolant leaks through damaged seals could create a slipping
hazard.

10

Improper coolant use includes, but is not limited to, these points:

• Do not use plain water. This causes machine components to rust.

• Do not use flammable coolants.

• Do not use straight or “neat” mineral-oil products. These products cause damage to
rubber seals and tubing throughout the machine. If you use a minimum-quantity
lubrication system for near-dry machining, use only the recommended oils.

Machine coolant must be water-soluble, synthetic oil-based or synthetic-based coolant or
lubricant.

NOTE: Be sure to maintain your coolant mixture to keep the coolant

concentrate at acceptable levels. Improperly maintained coolant
mixtures can allow machine components to rust. Rust damage is not
covered by your warranty.

Ask your HFO or your coolant dealer if you have questions about the specific coolant that
you plan to use. The Haas Resource Center website has videos and other general
information about coolant use and maintenance. You can also scan the code below with
your mobile device to directly access this information.

Safety

1.6 Safety Decals

The Haas factory puts decals on your machine to quickly communicate possible hazards.
If decals become damaged or worn, or if you need additional decals to emphasize a
particular safety point, contact your Haas Factory Outlet (HFO).

NOTE: Never alter or remove any safety decal or symbol.

Be sure to familiarize yourself with the symbols on the safety decals. The symbols are
designed to quickly tell you the type of information they give:

Safety

Machining operations can create hazardous chips, dust or mist. This is
function of the materials being cut, the metalworking fluid and cutting tools
used and the machining speeds/feeds.
It is up to the owner/operator of the machine to determine if personal
protective equipment such as safety goggles or a respirator is required
and also if a mist extraction system is needed. All enclosed models
have a provision for connecting a mist extraction system.
Always read and understand the Safety Data Sheets (SDS) for the
workpiece material, the cutting tools and the metalworking fluid.

Wireless Intuitive Probing System (WIPS)

Chapter 4: Wireless Intuitive Probing

System (WIPS)

4.1 UMC WIPS Basics

The Wireless Intuitive Probing System (WIPS) comes standard with the UMC-750. This
system can perform all of the standard probe routines found in the WIPS templates, and
also includes special probe routines specifically for the UMC. These special probe routines
use a tooling ball on a magnetic base to automatically find the machine’s centers of rotation.
Refer to page 5 for more information on this process.

Normally, you use WIPS to set tool and work offsets, but the UMC-750 includes a master
gauge length tool in case you need to set offsets manually (if, for example, a probe stylus
breaks or the batteries lose power). The gage length tool included with your machine has
a unique length that is etched on the tool.

NOTE: If you set the tool length offsets manually, you must also set the Z-Axis

work offset manually.

4.2 UMC VPS Basics

The Visual Programing System (VPS) (which contains Wireless Intuitive Probing (WIPS))
comes standard with the UMC-750. This system can perform all of the standard probe
routines found in the WIPS templates, and also includes special probe routines specifically
for the UMC. These special probe routines use a tooling ball to automatically find the
machine’s centers of rotation. Refer to page 5 for more information on this process.

Normally, you use WIPS to set tool and work offsets, but the UMC-750 includes a master
gauge length tool in case you need to set offsets manually (if, for example, a probe stylus

Machine Rotary Zero Point (MRZP) Offsets

4.3 Machine Rotary Zero Point (MRZP) Offsets

The Machine Rotary Zero Point (MRZP) Offsets are control settings that define the location
of the centers of rotation for the rotary table relative to the linear axes home position.
Settings 255, 256, and 257 define the following:

255 – MRZP X Offset

Location of the B Axis rotary center point relative to the X Axis home position.

256 – MRZP Y Offset

Location of the C Axis rotary center point relative to the Y Axis home position.

257 – MRZP Z Offset

Location of the B Axis rotary center point relative to the Z Axis home position.

The value stored in these settings is the distance from the home position of a linear axis to
the center of rotation of a rotary axis. Setting 9 determines if the values are shown in inches
or millimeters.

The Machine Rotary Zero Point (MRZP) Offsets are set at the factory.

4.3.1 Check MRZP Offsets with VPS

The MRZP offsets can change over time. To make sure the UMC-750, UMC-750SS MRZP
Offsets are correct do the following:

1. Place the tooling ball in the center of the X axis.

IMPORTANT: Make sure that the tooling ball is tightly attached to the calibration

assembly. Do not over tighten the tooling ball.

G234 - Tool Center Point Control (TCPC)

Chapter 5: G234 - Tool Center Point

Control (TCPC)

5.1 G234 - Tool Center Point Control (TCPC)

(Group 08)

G234 Tool Center Point Control (TCPC) is a software feature in the Haas CNC control that
allows a machine to correctly run a contouring 4- or 5-axis program when the workpiece is
not located in the exact location specified by a CAM-generated program. This eliminates
the need to repost a program from the CAM system when the programmed and the actual
workpiece locations are different.

The Haas CNC control combines the known centers of rotation for the rotary table (MRZP)
and the location of the workpiece (e.g., active work offset G54) into a coordinate system.
TCPC makes sure that this coordinate system remains fixed relative to the table; when the
rotary axes rotate, the linear coordinate system rotates with them. Like any other work
setup, the workpiece must have a work offset applied to it. This tells the Haas CNC control
where the workpiece is located on the machine table.

The conceptual example and illustrations in this section represent a line segment from a
full 4- or 5-axis program.

NOTE: For clarity, the illustrations in this section do not depict workholding.

Also, as conceptual, representative drawings, they are not to scale
and may not depict the exact axis motion described in the text.

The straight line edge highlighted in Figure F5.1 is defined by point (X0, Y0, Z0) and point
(X0, Y-1., Z0). Movement along the Y Axis is all that is required for the machine to create
this edge. The location of the workpiece is defined by work offset G54.

F5.1: Location of Workpiece Defined by G54

In Figure F5.2, the B and C Axes have been rotated 15 degrees each. To create the same
edge, the machine needs to make an interpolated move with the X, Y, and Z Axes. Without
TCPC, you would need to repost the CAM program for the machine to correctly create this
edge.

F5.2: G234 (TCPC) Off and the B and C Axes Rotated

TCPC is invoked in Figure F5.3. The Haas CNC control knows the centers of rotation for
the rotary table (MRZP), and the location of the workpiece (active work offset G54). This
data is used to produce the desired machine motion from the original CAM-generated
program. The machine follows an interpolated X-Y-Z path to create this edge, even though
the program simply commands a single-axis move along the Y Axis.

G234 - Tool Center Point Control (TCPC) (Group 08)

These key presses and program codes cancel G234:

•[EMERGENCY STOP]

•[RESET]

•[HANDLE JOG]

•[LIST PROGRAM]

• M02 – Program End

• M30 – Program End and Reset

• G43 – Tool Length Compensation +

• G44 – Tool Length Compensation -

• G49 – G43 / G44 / G143 Cancel

These codes will NOT cancel G234:

• M00 – Program Stop

• M01 – Optional Stop

These key presses and program codes impact G234:

• G234 invokes TCPC and cancels G43.

• When using tool length compensation, either G43 or G234 must be active. G43 and
G234 cannot be active at the same time.

• G234 cancels the previous H-code. An H-code must therefore be placed on the same
block as G234.

• G234 cannot be used at the same time as G254 (DWO).

36

These codes ignore 234:

• G28 – Return to Machine Zero Through Optional Reference Point

• G29 – Move to Location Thru G29 Reference Point

• G53 – Non-Modal Machine Coordinate Selection

• M06 – Tool Change

Invoking G234 (TCPC) rotates the work envelope. If the position is close to the travel limits,
the rotation can put the current work position outside of travel limits and cause an over
travel alarm. To solve this, command the machine to the center of the work offset (or near
the center of the table on a UMC), and then invoke G234 (TCPC).

G234 (TCPC) is intended for simultaneous 4- and 5-axis contouring programs. An active
work offset (G54, G55, etc.) is required to use G234.

G254 - Dynamic Work Offset (DWO)

Chapter 6: G254 - Dynamic Work Offset

(DWO)

6.1 G254 - Dynamic Work Offset (DWO) (Group 23)

G254 Dynamic Work Offset (DWO) is similar to TCPC, except that it is designed for use
with 3+1 or 3+2 positioning, not for simultaneous 4- or 5-axis machining. If the program
does not make use of the tilt and rotary Axes, there is no need to use DWO.

CAUTION: The B-Axis value of the work offset you use with G254 MUST be zero.

With DWO, you no longer need to set the workpiece in the exact position as programmed
in the CAM system. DWO applies the appropriate offsets to account for the differences
between the programmed workpiece location and the actual workpiece location. This
eliminates the need to repost a program from the CAM system when the programmed and
actual workpiece locations are different.

The control knows the centers of rotation for the rotary table (MRZP) and the location of the
workpiece (active work offset). This data is used to produce the desired machine motion
from the original CAM-generated program. Therefore, it is recommended that G254 be
invoked after the desired work offset is commanded, and after any rotational command to
position the 4th and 5th axes.

After G254 is invoked, you must specify an X, Y, and Z Axis position before a cutting
command, even if it recalls the current position. The program should specify the X- and Y
Axis position in one block and the Z Axis in a separate block.

CAUTION: Before rotary motion, use a G53 Non-Modal Machine Coordinate

motion command to safely retract the tool from the workpiece and
allow clearance for the rotary motion. After the rotary motion finishes,
specify an X-, Y-, and Z-Axis position before a cutting command, even
if it recalls the current position. The program should specify the X- and
Y-Axis position in one block and the Z-Axis position in a separate
block.

CAUTION: Be sure to cancel G254 with G255 when your program does

simultaneous 4- or 5-axis machining.

NOTE: For clarity, the illustrations in this section do not depict workholding.

The block in the figure below was programmed in the CAM system with the top center hole
located at the center of the pallet and defined as X0, Y0, Z0.

F6.1: Original Programmed Position

In the figure below, the actual workpiece is not located in this programmed position. The
center of the workpiece is actually located at X1, Y-1, Z0, and is defined as G54.

F6.2: Center at G54, DWO Off

DWO is invoked in the figure below. The control knows the centers of rotation for the rotary
table (MRZP), and the location of the workpiece (active work offset G54). The control uses
this data to apply the appropriate offset adjustments to make sure that the proper toolpath
is applied to the workpiece, as intended by the CAM-generated program. This eliminates
the need to repost a program from the CAM system when the programmed and actual
workpiece locations are different.

•[EMERGENCY STOP]

•[RESET]

•[HANDLE JOG]

•[LIST PROGRAM]

• G255 – Cancel DWO

• M02 – Program End

• M30 – Program End and Reset

These codes will NOT cancel G254:

Some codes ignore G254. These codes will not apply rotational deltas:

• *G28 – Return to Machine Zero Through Optional Reference Point

• *G29 – Move to Location Through G29 Reference Point

• G53 – Non-Modal Machine Coordinate Selection

• M06 – Tool Change

*It is strongly recommended that you not use G28 or G29 while G254 is active, nor when
the B and C Axes are not at zero.

40

1. G254 (DWO) is intended for 3+1 and 3+2 machining, where the B and C Axes are
used to position only.

2. An active work offset (G54, G55, etc.) must be applied before G254 is commanded.

3. All rotary motion must be complete before G254 is commanded.

4. After G254 is invoked, you must specify an X-, Y-, and Z-Axis position prior to any
cutting command, even if it recalls the current position. It is recommended to specify
the X and Y Axes in one block, and the Z Axis in a separate block.

5. Cancel G254 with G255 immediately after use and before ANY rotary motion.

6. Cancel G254 with G255 any time simultaneous 4- or 5-axis machining is performed.

7. Cancel G254 with G255 and retract the cutting tool to a safe location before the
workpiece is repositioned.

Setting Work and Tool Offsets

Chapter 7: Setting Work and Tool

Offsets

7.1 Set the B-Axis Work Offset

If the fixture or workpiece requires you to adjust the B Axis to achieve the proper alignment
for machining, use this procedure to adjust and record the B-Axis work offset.

CAUTION: Do not use a B-Axis offset if your program uses Dynamic Work Offsets

(G254). The B-Axis offset value must be zero.

1. Adjust the B Axis until the workpiece is positioned to the same orientation established
in the program. Typically, the top surface of the fixture or workpiece is perpendicular
to the Z Axis.

2. Navigate to [OFFSET]>Work. Scroll to the work offset value used in the program
(G54 in this example).

3. Highlight the value in the B Axis column. Press [PART ZERO SET] to record the
offset.

7.2 Set the C-Axis Work Offset

NOTE: If the fixture or workpiece requires you to adjust the C Axis to achieve

the proper alignment for machining, use the following procedure to
adjust and record the C-Axis work offset.

41

Set the X-, Y-, and Z-Axis Work Offsets Manually

F7.1: Setting the C-Axis Workpiece Orientation

1. Place the workpiece on the platter (workholding not shown). Adjust the C Axis until
the workpiece is positioned to the same orientation established in the program.
Typically, a reference feature on the fixture or workpiece is parallel to the X or Y Axis.

2. Navigate to [OFFSET]>Work. Scroll to the work offset value used in the program
(G54 in this example).

3. Highlight the value in the C Axis column. Press [PART ZERO SET] to record
the offset.

7.3 Set the X-, Y-, and Z-Axis Work Offsets

Manually

NOTE: Use this procedure if the WIPS probe is disabled.

NOTE: Refer to the Haas Mill Operator’s Manual for basic offset and

toolsetting methods.

42

1. Jog the X and Y Axes to the zero position established in the program.

F7.2: UMC-750 X- and Y-Axis Zero Position

2. Navigate to [OFFSET]>Work. Scroll to the work offset value used in the program
(G54 in this example).

3. Select the X Axis column of your work coordinate offset and press [PART ZERO
SET] to set the X-Axis zero position.

4. Press [PART ZERO SET] again to set the Y-Axis zero position.

Setting Work and Tool Offsets

F7.3: X-Axis Zero Position Set and Y-Axis Zero Position Set

5. Determine a tool set plane to be used for setting all tool length offsets; for example,
use the top surface of the workpiece.

(G00 G90 G54 B0 C0)

44

8. Select the Z AXIS column of your work coordinate offset.

9. Jog the Z Axis to the tool set plane. Make sure that the end of the gage tool you are
using just touches the tool set plane. You will touch-off all of your tools on this
surface.

F7.6: Jog the End of the Gage Tool to the Tool Set Plane

Setting Work and Tool Offsets

10. With the Z Axis column of the work offset used in the program highlighted (G54 in this
example), press [PART ZERO SET].

11. Subtract the length of the master gage tool supplied with the machine from the value
shown in the Z Axis column. Enter this value as the offset in the Z Axis column.

For example, if the Z-Axis work offset is -7.0000 and the master gage tool length is

5.0000, the new Z-Axis work offset is -12.0000.

12. Touch-off each of the tools in your program to the Z set plane to establish their length
offsets.

45

Set the X-, Y-, and Z-Axis Work Offsets with WIPS

7.4 Set the X-, Y-, and Z-Axis Work Offsets with

WIPS

If you are not using the WIPS system, go to the Set the X-, Y-, and Z-Axis Work Offsets
Manually section, starting on page 41.

NOTE: Make sure that the tool setting probe and the work probe are

calibrated. Refer to the Haas WIPS manual (96-10002) for the
calibration procedure.

11. Press [CYCLE START]. The probe measures the distance to the top of the part and
records the value in the Z Axis column work offset for G54.

12. Use the tool setting probe to set each of your tool length offsets.

Rotary Unwind and Setting 247

Chapter 8: Rotary Unwind and Setting

247

8.1 Quick Rotary G28 (Home)

This feature lets you to return the rotary axis to zero within 359.99 degrees, saving time and
motion. The rotary axis will need to have rotated at least 360 degrees for the unwind feature
to be a benefit.

For example, if the rotary axis has rotated a total of 960 degrees through the course of a
program, a rotary axis zero return command without the unwind feature will cause the axis
to rotate back through all 960 degrees of rotation before the Haas CNC control considers
the axis at home.

With Quick Rotary G28 enabled, the rotary axis rotates toward zero just enough to reach
its home position; the control ignores all previous revolutions. In the example of 960
degrees of rotation, the rotary axis rotates a negative 240 degrees and stops at the
machine home position.

To use this feature, Setting 108 must be set to ON. The unwind command must be an
incremental (G91) Home command (G28).

For example:

G54 G01 F100. C960. (rotary axis TURNS 960 DEGREES CLOCKWISE)
G28 G91 C0. (rotary axis ROTATES 240 DEGREES COUNTER-CLOCKWISE
TO HOME)

8.2 247 - Simultaneous XYZ Motion in Tool Change

Setting 247 defines how the axes move during a tool change. If Setting 247 is OFF, the
Z Axis retracts first, followed by X- and Y-Axis motion. This feature can be useful in avoiding
tool collisions for some fixture configurations. If Setting 247 is ON, the axes move
simultaneously. This may cause collisions between the tool and the workpiece, due to B­and C-Axis rotations. It is strongly recommended that this setting remain OFF on the
UMC-750, due to the high potential for collisions.
