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.

CAUTION

1 Immediately after switching on the power, do not touch any of the keys on the

MDI unit until the position display or alarm screen appears on the CNC unit.

Some of the keys on the MDI unit 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.

2 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.

3 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.

SAFETY

PRECAUTIONS

s-3

CAUTION

4 The liquid-crystal display is manufactured with very precise fabrication

technology. Some pixels may not be turned on or may remain on. This
phenomenon is a common attribute of LCDs and is not a defect.

NOTE

1 Programs, parameters, and macro variables are stored in non-volatile 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 non-volatile 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.

2 The number of times to write machining programs to the non-volatile memory is

limited.
You must use "High-speed program management" when registration and the
deletion of the machining programs are frequently repeated in such case that the
machining programs are automatically downloaded from a personal computer at
each machining.
In "High-speed program management", the program is not saved to the
non-volatile memory at registration, modification, or deletion of programs.

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 carefully such that you are fully familiar with
their contents.

WARNING

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.

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.

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.

SAFETY PRECAUTIONS

B-64604EN-1/01

s-4

WARNING

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.

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.

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.

Interference check for each path

Interference check for each path function 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.

Same address command in same block

The G code or M code including the same address cannot be commanded on
the same block. If you use the same address, it may result in the machine
behaving unexpectedly, possibly causing damage to the workpiece and/or
machine itself, or injury to the user. Command on separate block.

（

About

address P, refer to the appendix “List of functions include address P in the
program command”

）

CAUTION

Absolute/incremental mode

If a program created with absolute values is run in incremental mode, or vice
versa, the machine may behave unexpectedly.

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.

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.

Programmable mirror image

Note that programmed operations vary considerably when a programmable
mirror image is enabled.

B-64604EN-1/01

SAFETY

PRECAUTIONS

s-5

CAUTION

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.

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 carefully, such that you are fully
familiar with their contents.

WARNING

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.

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.

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.

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.

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.

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.

SAFETY PRECAUTIONS

B-64604EN-1/01

s-6

WARNING

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.

Software operator's panel and menu switches

Using the software operator's panel and menu switches, in combination with the
MDI unit, 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 unit keys are operated inadvertently, the machine
may behave unexpectedly, possibly damaging the tool, the machine itself, the
workpiece, or causing injury to the user.

RESET key

Pressing the RESET key stops the currently running program. As a result, the
servo axes are stopped. However, the RESET key may fail to function for
reasons such as an MDI unit problem. So, when the motors must be stopped,
use the emergency stop button instead of the RESET key to ensure security.

CAUTION

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.

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.

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.

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.

B-64604EN-1/01

SAFETY

PRECAUTIONS

s-7

CAUTION

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.

WARNINGS RELATED TO DAILY MAINTENANCE

WARNING

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

and fitted 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 Section "METHOD OF REPLACING BATTERY" in the Chapter,
"ROUTINE MAINTENANCE" of OPERATOR’S MANUAL (Common to
Lathe/Machining Center System) for details of the battery replacement
procedure.

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 FANUC SERVO MOTOR

series Maintenance Manual for details

of the battery replacement procedure.

WARNING

Fuse replacement

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.

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 Part II, "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 Part III, "OPERATION".
