SAFETY PRECAUTIONS

GENERAL W ARNINGS 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.

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 of f. Such data may be deleted inadvertently,
however, or it may prove necessary to delete all data from nonvolatile memory as part of error
recovery.
T o 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.

1. Coordinate system setting

SAFETY PRECAUTIONS

W ARNINGS 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

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

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

B–63604EN/01

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.

1. Manual operation

SAFETY PRECAUTIONS

W ARNINGS 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

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.

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.

s–7

SAFETY PRECAUTIONS

WARNING

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.

B–63604EN/01

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.

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.

CAUTIONS ON
READING THIS
MANUAL

GENERAL1. GENERAL

CAUTION

1 The function of an CNC machine tool system depends not

only on the CNC, but on the combination of the machine
tool, its magnetic cabinet, the servo system, the CNC, the
operator’s panels, etc. It is too difficult to describe the
function, programming, and operation relating to all
combinations. This manual generally describes these from
the stand–point of the CNC. So, for details on a particular
CNC machine tool, refer to the manual issued by the
machine tool builder, which should take precedence over
this manual.

2 Headings are placed in the left margin so that the reader can

easily access necessary information. When locating the
necessary information, the reader can save time by
searching though these headings.

3 This manual describes as many reasonable variations in

equipment usage as possible. It cannot address every
combination of features, options and commands that
should not be attempted.
If a particular combination of operations is not described, it
should not be attempted.

CAUTIONS ON
V ARIOUS KINDS OF
DATA

CAUTION

Machining programs, parameters, variables, etc. are stored
in the CNC unit internal non–volatile memory. In general,
these contents are not lost by the switching ON/OFF of the
power. However, it is possible that a state can occur where
precious data stored in the non–volatile memory has to be
deleted, because of deletions from a maloperation, or by a
failure restoration. In order to restore rapidly when this kind
of mishap occurs, it is recommended that you create a copy
of the various kinds of data beforehand.

Explanations

A CNC machine tool is provided with a fixed position. Normally, tool
change and programming of absolute zero point as described later are
performed at this position. This position is called the reference position.

Tool post

The tool can be moved to the reference position in two ways:

1. Manual reference position return (See III–3.1)
Reference position return is performed by manual button operation.

2. Automatic reference position return (See II–6)
In general, manual reference position return is performed first after
the power is turned on. In order to move the tool to the reference
position for tool change thereafter, the function of automatic
reference position return is used.

PROGRAMMING

1. GENERAL

The tool moves on the coordinate system specified by the CNC in
accordance with the command program generated with respect to the
coordinate system on the part drawing, and cuts a workpiece into a shape
on the drawing.
Therefore, in order to correctly cut the workpiece as specified on the
drawing, the two coordinate systems must be set at the same position.

D Methods of setting the

two coordinate systems
in the same position

The following method is usually used to define two coordinate systems
at the same location.

CUTTING SPEED –
SPINDLE SPEED
FUNCTION

Examples

The speed of the tool with respect to the workpiece when the workpiece
is cut is called the cutting speed.
As for the CNC, the cutting speed can be specified by the spindle speed

–1

in min

unit.

<When a workpiece 200 mm in diameter should be machined at
a cutting speed of 300 m/min. >

–1

The spindle speed is approximately 478 min

, which is obtained from

N=1000v/πD. Hence the following command is required:

S478 ;

Commands related to the spindle speed are called the spindle speed
function (See II–9).
The cutting speed v (m/min) can also be specified directly by the speed
value. Even when the workpiece diameter is changed, the CNC changes
the spindle speed so that the cutting speed remains constant.
This function is called the constant surface speed control function
(See II–9.3).

When drilling, tapping, boring, milling or the like, is performed, it is
necessary to select a suitable tool. When a number is assigned to each tool
and the number is specified in the program, the corresponding tool is
selected.

COMMAND FOR
MACHINE
OPERATIONS –

FUNCTION

When machining is actually started, it is necessary to rotate the spindle,
and feed coolant. For this purpose, on–off operations of spindle motor and
coolant valve should be controlled (See II–11).

Fig. 1.6 Command for machine operations

The function of specifying the on–off operations of the components of the
machine is called the miscellaneous function. In general, the function is
specified by an M code.
For example, when M03 is specified, the spindle is rotated clockwise at
the specified spindle speed.

A group of commands given to the CNC for operating the machine is
called the program. By specifying the commands, the tool is moved along
a straight line or an arc, or the spindle motor is turned on and off.
In the program, specify the commands in the sequence of actual tool
movements.

the number for discriminating each program is called the program number
(See II–12).

When machining of the same pattern appears at many portions of a
program, a program for the pattern is created. This is called the
subprogram. On the other hand, the original program is called the main
program. When a subprogram execution command appears during
execution of the main program, commands of the subprogram are
executed. When execution of the subprogram is finished, the sequence
returns to the main program.

D Machining using the end

of cutter – Tool length
compensation function

Usually, several tools are used for machining one workpiece. The tools
have different tool length. It is very troublesome to change the program
in accordance with the tools.
Therefore, the length of each tool used should be measured in advance.
By setting the difference between the length of the standard tool and the
length of each tool in the CNC (data display and setting : see III–11),
machining can be performed without altering the program even when the
tool is changed. This function is called tool length compensation.
