(a) Tool life management method
0 : Usage time
This manages by the cutting execution time.
1 : No. of mounting times
This manages by the No. of times the tool became the
spindle tool in tool replacement, etc.
However, in the case where the cutting feed command
(G01, G02, G03 etc.) is not executed even once after
becoming the spindle tool, the No. of times is not counted.
2 : Usage count
This is counted when the rapid traverse command (G00
etc.) is changed to the cutting feed command (G01, G02,
G03 etc.). However, this is invalid in the case of a rapid
traverse or cutting feed command with no movement.

(b) Tool radius compensation data format
(c) Tool length compensation data format
0 : Compensation No.
The tool life management data compensation data is
handled as a compensation No., this No. replaces the
compensation No. designated in the process program,
and compensation is performed.
1 : Added compensation amount
The tool life management data compensation data is
handled as the added compensation amount, an addition
is made to the compensation amount shown with the
compensation No. designated in the process program,
and compensation is performed.
2 : Direct compensation amount
The tool life management data compensation data is
handled as the direct compensation amount, this No.
replaces the compensation amount shown for the
compensation No. designated in the process program,
and compensation is performed.
This depends on the data format designated in "Mthd".
This depends on the machine tool builder specifications.
Set the usage time (minutes), attachment count (No. of times
attached to the spindle), or usage count (No. of holes drilled) for
the life for each tool based on the data format set for " Method " .
The life is infinite when "0" is set.
