2.3.5.2 Tool Life Incrementation Methods
The tool life can be incre
mented either by time method or by the No. of uses (count) method.
If the USED data equals or exceeds the LIFE data as a result of incrementation, a spare tool will be
selected from that tool's group by the next relevant group selection command (T****99). After that, the
incrementation will be for the newly selected tool (the spare tool selected). If the life of all tools in a group is
reached, and a spare tool cannot be selected, the incrementation will continue for the last tool selected.
(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
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.
