3. Tool Offset (L system)
3.5 Tool Life Management II
I-105
Refer to "3 (II). Tool Offset (M system)" for M system.
(1) Time incrementation with the time method
The time the tool is used in the cutting mode (G01, G02, G03, G31, G33, etc.) is incremented in 100ms
units.
The time is not incremented during dwell, machine lock, miscellaneous function lock, dry run or single
block status.
(Note) •
The max. life value is 999999 min.
• The data on the TOOL LIFE screen is displayed in minute units.
(2) No. of uses (count) incrementation with the count method
(a) Type 1 (#1277 ext13/bit0: 0)
Incrementation is carried out when the No. of the tool being used changes by the execution of a tool
selection command (T****99) during the cutting mode (except during machine lock, miscellaneous
function lock, dry run, and single block states). (If the mode never changes to the cutting mode after
the tool No. changes, the count is not incremented.)
(Note) •
The max. life value is 999999 times.
• If only the compensation No. for the current tool changes, the count is not incremented.
If the T code of the current tool is 12345678:
T 1 2 3 4 5 6 7 8
Compensation No.: The count is not incremented,
even if this changes.
Tool No.: The count is incremented when this
changes.
The count for group 01 is 1 time.
(Note)
The count is for one program execution.
If the program is executed again after
resetting the count will be incremented.
The count for group 01 is 3 times.

(b) Type 2 (#1277 ext13/bit0: 1)
Only the group used for cutting from when the machining program starts to when it is reset is
incremented by "1". The count is made at the reset.
If recount M is commanded, the group used up to that point will be incremented by "1" in the
counter.
(Note 1) A count is not made in the machine lock, miscellaneous function lock or dryrun states.
(Note 2) During single block, select whether to count with the parameter.
(Note 3) The maximum value of the life is 999999 times.
