B-63784EN/01 SAFETY PRECAUTIONS
GENERAL WARNINGS AND CAUTIONS
WARNING
1. Never attempt to machine a workpiece without first checking the operation of the machine. Before
starting a production run, ensure that the machine is operating correctly by performing a trial run
using, for example, the single block, feedrate override, or machine lock function or by operating the
machine with neither a tool nor workpiece mounted. Failure to confirm the correct operation of the
machine may result in the machine behaving unexpectedly, possibly causing damage to the
workpiece and/or machine itself, or injury to the user.
2. Before operating the machine, thoroughly check the entered data.
Operating the machine with incorrectly specified data may result in the machine behaving
unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user.
3. Ensure that the specified feedrate is appropriate for the intended operation. Generally, for each
machine, there is a maximum allowable feedrate.
The appropriate feedrate varies with the intended operation. Refer to the manual provided with the
machine to determine the maximum allowable feedrate.
If a machine is run at other than the correct speed, it may behave unexpectedly, possibly causing
damage to the workpiece and/or machine itself, or injury to the user.
4. When using a tool compensation function, thoroughly check the direction and amount of
compensation.
Operating the machine with incorrectly specified data may result in the machine behaving
unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user.
5. The parameters for the CNC and PMC are factory-set. Usually, there is not need to change them.
When, however, there is not alternative other than to change a parameter, ensure that you fully
understand the function of the parameter before making any change.
Failure to set a parameter correctly may result in the machine behaving unexpectedly, possibly
causing damage to the workpiece and/or machine itself, or injury to the user.
6. Immediately after switching on the power, do not touch any of the keys on the MDI panel until the
position display or alarm screen appears on the CNC unit.
Some of the keys on the MDI panel are dedicated to maintenance or other special operations.
Pressing any of these keys may place the CNC unit in other than its normal state. Starting the
machine in this state may cause it to behave unexpectedly.
7. The operator's manual and programming manual supplied with a CNC unit provide an overall
description of the machine's functions, including any optional functions. Note that the optional
functions will vary from one machine model to another. Therefore, some functions described in the
manuals may not actually be available for a particular model. Check the specification of the
machine if in doubt.
s-3
SAFETY PRECAUTIONS B-63784EN/01
WARNING
8. Some functions may have been implemented at the request of the machine-tool builder. When using
such functions, refer to the manual supplied by the machine-tool builder for details of their use and
any related cautions.
NOTE
Programs, parameters, and macro variables are stored in nonvolatile memory in the CNC unit. Usually,
they are retained even if the power is turned off.
Such data may be deleted inadvertently, however, or it may prove necessary to delete all data from
nonvolatile memory as part of error recovery.
To guard against the occurrence of the above, and assure quick restoration of deleted data, backup all
vital data, and keep the backup copy in a safe place.
s-4
B-63784EN/01 SAFETY PRECAUTIONS
WARNINGS AND CAUTIONS RELATED TO PROGRAMMING
This section covers the major safety precautions related to programming. Before attempting to perform
programming, read the supplied operator's manual and programming manual carefully such that you are
fully familiar with their contents.
WARNING
1.Coordinate system setting
If a coordinate system is established incorrectly, the machine may behave unexpectedly as a result of the
program issuing an otherwise valid move command.
Such an unexpected operation may damage the tool, the machine itself, the workpiece, or cause injury to
the user.
2.Positioning by nonlinear interpolation
When performing positioning by nonlinear interpolation (positioning by nonlinear movement between
the start and end points), the tool path must be carefully confirmed before performing programming.
Positioning involves rapid traverse. If the tool collides with the workpiece, it may damage the tool, the
machine itself, the workpiece, or cause injury to the user.
3.Function involving a rotation axis
When programming polar coordinate interpolation or normal-direction (perpendicular) control, pay
careful attention to the speed of the rotation axis. Incorrect programming may result in the rotation axis
speed becoming excessively high, such that centrifugal force causes the chuck to lose its grip on the
workpiece if the latter is not mounted securely.
Such mishap is likely to damage the tool, the machine itself, the workpiece, or cause injury to the user.
4.Inch/metric conversion
Switching between inch and metric inputs does not convert the measurement units of data such as the
workpiece origin offset, parameter, and current position.
Before starting the machine, therefore, determine which measurement units are being used. Attempting
to perform an operation with invalid data specified may damage the tool, the machine itself, the
workpiece, or cause injury to the user.
5.Constant surface speed control
When an axis subject to constant surface speed control approaches the origin of the workpiece
coordinate system, the spindle speed may become excessively high. Therefore, it is necessary to specify
a maximum allowable speed. Specifying the maximum allowable speed incorrectly may damage the
tool, the machine itself, the workpiece, or cause injury to the user.
s-5
SAFETY PRECAUTIONS B-63784EN/01
WARNING
6.Stroke check
After switching on the power, perform a manual reference position return as required. Stroke check is
not possible before manual reference position return is performed. Note that when stroke check is
disabled, an alarm is not issued even if a stroke limit is exceeded, possibly damaging the tool, the
machine itself, the workpiece, or causing injury to the user.
7. Tool post interference check
A tool post interference check is performed based on the tool data specified during automatic operation.
If the tool specification does not match the tool actually being used, the interference check cannot be
made correctly, possibly damaging the tool or the machine itself, or causing injury to the user.
After switching on the power, or after selecting a tool post manually, always start automatic operation
and specify the tool number of the tool to be used.
8. Absolute/incremental mode
If a program created with absolute values is run in incremental mode, or vice versa, the machine may
behave unexpectedly.
9.Plane selection
If an incorrect plane is specified for circular interpolation, helical interpolation, or a canned cycle, the
machine may behave unexpectedly. Refer to the descriptions of the respective functions for details.
10.Torque limit skip
Before attempting a torque limit skip, apply the torque limit. If a torque limit skip is specified without
the torque limit actually being applied, a move command will be executed without performing a skip.
11.Programmable mirror image
Note that programmed operations vary considerably when a programmable mirror image is enabled.
12.Compensation function
If a command based on the machine coordinate system or a reference position return command is issued
in compensation function mode, compensation is temporarily canceled, resulting in the unexpected
behavior of the machine.
Before issuing any of the above commands, therefore, always cancel compensation function mode.
s-6
B-63784EN/01 SAFETY PRECAUTIONS
WARNINGS AND CAUTIONS RELATED TO HANDLING
This section presents safety precautions related to the handling of machine tools. Before attempting to
operate your machine, read the supplied operator's manual and programming manual carefully, such
that you are fully familiar with their contents.
WARNING
1.Manual operation
When operating the machine manually, determine the current position of the tool and workpiece, and
ensure that the movement axis, direction, and feedrate have been specified correctly. Incorrect
operation of the machine may damage the tool, the machine itself, the workpiece, or cause injury to the
operator.
2.Manual reference position return
After switching on the power, perform manual reference position return as required.
If the machine is operated without first performing manual reference position return, it may behave
unexpectedly. Stroke check is not possible before manual reference position return is performed.
An unexpected operation of the machine may damage the tool, the machine itself, the workpiece, or
cause injury to the user.
3.Manual numeric command
When issuing a manual numeric command, determine the current position of the tool and workpiece,
and ensure that the movement axis, direction, and command have been specified correctly, and that the
entered values are valid.
Attempting to operate the machine with an invalid command specified may damage the tool, the
machine itself, the workpiece, or cause injury to the operator.
4.Manual handle feed
In manual handle feed, rotating the handle with a large scale factor, such as 100, applied causes the tool
and table to move rapidly. Careless handling may damage the tool and/or machine, or cause injury to
the user.
5.Disabled override
If override is disabled (according to the specification in a macro variable) during threading, rigid
tapping, or other tapping, the speed cannot be predicted, possibly damaging the tool, the machine itself,
the workpiece, or causing injury to the operator.
s-7
SAFETY PRECAUTIONS B-63784EN/01
WARNING
6.Origin/preset operation
Basically, never attempt an origin/preset operation when the machine is operating under the control of a
program. Otherwise, the machine may behave unexpectedly, possibly damaging the tool, the machine
itself, the tool, or causing injury to the user.
7.Workpiece coordinate system shift
Manual intervention, machine lock, or mirror imaging may shift the workpiece coordinate system.
Before attempting to operate the machine under the control of a program, confirm the coordinate system
carefully.
If the machine is operated under the control of a program without making allowances for any shift in the
workpiece coordinate system, the machine may behave unexpectedly, possibly damaging the tool, the
machine itself, the workpiece, or causing injury to the operator.
8.Software operator's panel and menu switches
Using the software operator's panel and menu switches, in combination with the MDI panel, it is
possible to specify operations not supported by the machine operator's panel, such as mode change,
override value change, and jog feed commands.
Note, however, that if the MDI panel keys are operated inadvertently, the machine may behave
unexpectedly, possibly damaging the tool, the machine itself, the workpiece, or causing injury to the
user.
9.Manual intervention
If manual intervention is performed during programmed operation of the machine, the tool path may
vary when the machine is restarted. Before restarting the machine after manual intervention, therefore,
confirm the settings of the manual absolute switches, parameters, and absolute/incremental command
mode.
10.Feed hold, override, and single block
The feed hold, feedrate override, and single block functions can be disabled using custom macro system
variable #3004. Be careful when operating the machine in this case.
11.Dry run
Usually, a dry run is used to confirm the operation of the machine. During a dry run, the machine
operates at dry run speed, which differs from the corresponding programmed feedrate. Note that the dry
run speed may sometimes be higher than the programmed feed rate.
s-8
B-63784EN/01 SAFETY PRECAUTIONS
WARNING
12.Cutter and tool nose radius compensation in MDI mode
Pay careful attention to a tool path specified by a command in MDI mode, because cutter or tool nose
radius compensation is not applied. When a command is entered from the MDI to interrupt in automatic
operation in cutter or tool nose radius compensation mode, pay particular attention to the tool path when
automatic operation is subsequently resumed. Refer to the descriptions of the corresponding functions
for details.
13.Program editing
If the machine is stopped, after which the machining program is edited (modification, insertion, or
deletion), the machine may behave unexpectedly if machining is resumed under the control of that
program. Basically, do not modify, insert, or delete commands from a machining program while it is in
use.
s-9
SAFETY PRECAUTIONS B-63784EN/01
WARNINGS RELATED TO DAILY MAINTENANCE
WARNING
1.Memory backup battery replacement
When replacing the memory backup batteries, keep the power to the machine (CNC) turned on, and
apply an emergency stop to the machine. Because this work is performed with the power on and the
cabinet open, only those personnel who have received approved safety and maintenance training may
perform this work.
When replacing the batteries, be careful not to touch the high-voltage circuits (marked
with an insulating cover).
Touching the uncovered high-voltage circuits presents an extremely dangerous electric shock hazard.
NOTE
The CNC uses batteries to preserve the contents of its memory, because it must retain data such as
programs, offsets, and parameters even while external power is not applied.
If the battery voltage drops, a low battery voltage alarm is displayed on the machine operator's panel or
screen.
When a low battery voltage alarm is displayed, replace the batteries within a week. Otherwise, the
contents of the CNC's memory will be lost.
Refer to the Maintenance manual for details of the battery replacement procedure.

2.Absolute pulse coder battery replacement
When replacing the memory backup batteries, keep the power to the machine (CNC) turned on, and
apply an emergency stop to the machine. Because this work is performed with the power on and the
cabinet open, only those personnel who have received approved safety and maintenance training may
perform this work.
When replacing the batteries, be careful not to touch the high-voltage circuits (marked
and fitted
with an insulating cover).
Touching the uncovered high-voltage circuits presents an extremely dangerous electric shock hazard.
NOTE
The absolute pulse coder uses batteries to preserve its absolute position.
If the battery voltage drops, a low battery voltage alarm is displayed on the machine operator's panel or
screen.
When a low battery voltage alarm is displayed, replace the batteries within a week. Otherwise, the
absolute position data held by the pulse coder will be lost.
Refer to the Maintenance manual for details of the battery replacement procedure.
s-11
SAFETY PRECAUTIONS B-63784EN/01
WARNING
3.Fuse replacement
For some units, the chapter covering daily maintenance in the operator's manual or programming
manual describes the fuse replacement procedure.
Before replacing a blown fuse, however, it is necessary to locate and remove the cause of the blown
fuse.
For this reason, only those personnel who have received approved safety and maintenance training may
perform this work.
When replacing a fuse with the cabinet open, be careful not to touch the high-voltage circuits (marked
and fitted with an insulating cover).
Touching an uncovered high-voltage circuit presents an extremely dangerous electric shock hazard.

1.1 GENERAL FLOW OF OPERATION OF CNC MACHINE
TOOL
When machining the part using the CNC machine tool, first prepare the
program, then operate the CNC machine by using the program.
(1) First, prepare the program from a part drawing to operate the CNC
machine tool. How to prepare the program is described in the
OPERATOR’S MANUAL (PROGRAMMING).
(2) The program is to be read into the CNC system. Then, mount the
workpieces and tools on the machine, and operate the tools
according to the programming. Finally, execute the machining
actually. How to operate the CNC system is described in the
OPERATOR’S MANUAL (OPERATION).
