10.5.2

Registering, Changing, and Deleting Tool Life Management

Data

By programming, tool life management data can be registered in the
CNC, and registered tool life management data can be changed or
deleted.

Explanation

The program format varies depending on the following four types of
operation:

- Registration after deletion of all groups

After all registered tool life management data is deleted, programmed
tool life management data is registered.

- Change of tool life management data

Tool life management data can be set for a group for which no tool
life management data is registered, and already registered tool life
management data can be changed.

- Deletion of tool life management data

Tool life management data can be deleted.

- Setting of tool life count type

A count type (use duration or use count) can be set for each group
separately.

NOTE

1 A group number that is the same as the group

number of another group cannot be registered.
An attempt to register such a group number results
in alarm PS0431.

2 If an arbitrary group number (T) is 0, alarm PS0431

is issued.

3 If ever an arbitrary group number is specified, the T

command must be specified. If the T command is
omitted, alarm PS0149 is issued.

The function for specifying an arbitrary group number is available
only if the tool change type is the ATC type (bit 3 (TCT) of parameter
No. 5040 = 1).
If the tool change type is the ATC type, the format used for setting an
arbitrary group number is the same as for the M series.

Remaining life setting

If the tool life management B function is enabled (bit 4 (LFB) of
parameter No. 6805 = 1), and a remaining life value is to be set for
each group separately (bit 3 (GRP) of parameter No. 6802 = 1), a
remaining life value can be set as tool life management data by
programming a command.

NOTE

1 If the remaining life setting (R) is 0 or omitted, the

remaining life is assumed to be 0. In this case,
the tool life expiration prior notice function is
disabled.

2 The remaining life setting (R) cannot exceed the

life value (L). If an attempt is made to specify a
value greater than the life value, alarm PS0431 is
issued.

3 The remaining life setting (R) must be an unsigned

value having no decimal point.

4 The unit of the remaining life setting (R) depends

on the setting of bit 1 (FGL) of parameter No. 6805,
which selects the unit of the tool life value.

Tool life value
- If the life management B function is disabled

If the tool life management B function is disabled (bit 4 (LFB) of
parameter No. 6805 = 0), a tool life value is registered as a duration or
a use count according to the setting of bit 2 (LTM) of parameter No.
6800 or the setting of a count type (Q command). The maximum
values are listed below.

If the count type is duration specification, the unit of a life value

second, which is determined by the setting of bit 1 (FGL) of parameter
No. 6805.

10.5.3

Tool Life Management Commands in Machining Program

Explanation

- Commands

The following commands are used for tool life management:

○○○○○○○○

;

Specifies a tool group number.
The tool life management function selects, from a specified group, a
tool whose life has not expired, and outputs its T code signal.
In

{{{{{{{{

, specify the sum of the tool life management

ignore number specified in parameter No. 6810 and a desired group
number.
Example: To specify tool group number 1 when the tool life

management ignore number is 100, specify “T101;”.

NOTE

{{{{{{{{

is not greater than a tool life

management ignore number, the T code is treated
as an ordinary T code.

If an arbitrary group number is used (bit 4 (LFB) of parameter No.
6805 = 1, and bit 5 (TGN) of parameter No. 6802 = 1), it must be a
preset arbitrary group number rather than a tool group number
specified in

{{{{{{{{

Example: To specify tool group number 1 when arbitrary group

number 1234 is set for tool group number 1, specify T1234.

NOTE

1 If an arbitrary group number is used, the tool life

management ignore number specified in parameter
No. 6810 is not used.

2 If the group specified by

{{{{{{{{

is not

present, the CNC assumes that a tool not controlled
under the tool life management function is selected.

M06;

Terminates life management for the previously used tools, and begins
counting the life of a new tool selected with the T code.

NOTE

1 M06 is treated as an M code not involving buffering.
2 If more than one M code is to be specified within the

same block, specify M06 first among these M
codes.

H99;

Selects the H code registered in tool life management data for the
currently used tool to enable tool length offset. Parameter No. 13265
can be used to enable compensation according to an H code other than
H99.

B-63944EN/03

PROGRAMMING

10.TOOL FUNCTION (T FUNCTION)

- 291 -

H00;

Cancels tool length offset.

D99;

Selects the D code registered in tool life management data for the
currently used tool to perform cutter compensation.
Parameter No. 13266 can be used to enable compensation according to
a D code other than D99.

D00;

Cancels cutter compensation.

NOTE

H99 and D99 must be specified after the M06

command. If a code other than H99 or D99 or a
code other than the H or D code set, respectively, in
parameter No. 13265 or 13266 is specified following
M06, no H code or D code is selected for tool life
management data.

- Types

For tool life management, the four tool change types (types A to D)
listed below are used. Which type to use varies from one machine to
another. For details, refer to the relevant manual of each machine
tool builder.

Life counting is performed for a tool in the specified tool group if M06 is
specified next.

Life counting is
performed if a tool in
the tool group
specified in the
same block as M06
is specified.

Remarks

If the T command (retract tool
group) following the M06
command is not the currently
used tool group, alarm PS0155
is issued (if bit 6 (IGI) of
parameter No. 6800 = 0).

Normally, if a tool group number
command is specified alone, type B is
used. However, even if a tool group
number command is specified alone with
type C, no alarm is issued. (This means
that there is no difference in operation
between types B and C.)

If M06 is specified
alone, alarm PS0153
is raised.
