11. TOOL FUNCTION (T FUNCTION)
119
A tool life is specified either as the time of use (in minutes) or the
frequency of use, which depends on the parameter setting parameter No.
6800#2(LTM) .
Up to 4300 minutes in time or 9999 times in frequency can be specified
for a tool life.
The number of groups to be registered and the number of tools registered
per group can be combined in three ways. One of the three combinations
is set by a parameter No.6800#0,#1(Each GS1 and GS2).

0 1 32 8 32 16
1 0 64 4 64 8
1 1 16 16 128 4
In each of the cases listed above, the maximum number of tools which can
be registered is 512 or 256 depending, respectively, on whether the option
for 128 tool life control groups is used or not. When the option is not used,
set the parameters as follows: For up to 16 groups, with up to 16 tools
in each group, set GS1 = 0 and GS2 = 0. For up to 32 groups, with up to
8 tools in each group, set GS1 = 0 and GS2 = 1. To change the
combination, change the parameter, then set program is executed with the
old tool group combination set in the NC. Whenever the parameter is
changed, be sure to reexecute the group setting program.
The same tool number may appear anywhere any times in the program of
tool life data.
A T code for registering tools can usually consist of up to four digits.
When the option for 128 tool life control groups is used, however, it can
consist of up to six digits.
