Tool life
The life of tool is specified by a usage frequency (count) or usage
time (in minutes.)
Usage count
The usage count is incremented by 1 for each tool used in a program.
In other words, the usage count is incremented by 1 only when the
first tool group number and tool change command are specified after
the CNC unit enters the automatic operation state from the reset state.
NOTE
Even if the same tool group number is specified more
than once in a program, the usage count is only
incremented by 1 and no new tools are selected.
Usage time
When a tool change is specified (M06), tool life management is
started for the tool specified by the tool group number. In tool life
management, the time during which a tool is used in the cutting mode
is counted in four second increments. If tool group number changed
before the incremental time of four seconds elapses., the time is not
counted. (It is available to count the time in one second increment by
setting parameter No.6801#5(E1S) to 1.)
The time a tool is used for single block stop, feed hold, rapid traverse,
dwell, machine lock, and interlock is not counted.
