There are two ways to run a tool usage test for a pallet file:
The highlight in the pallet file is on a pallet entry: The TNC runs
the tool usage test for the entire pallet

Using a tool usage test
Before starting a program in the
Program Run, Full Sequence/
Single Block
operating modes, you can use the
TOOL USAGE
and
TOOL USAGE TEST
soft keys to check whether the tools being used
in the selected program are available and have sufficient remaining
service life. The TNC then compares the actual service-life values in
the tool table with the nominal values from the tool usage file.
After you have pressed the
TOOL USAGE TEST
soft key, the TNC
displays the result of the tool usage test in a pop-up window. To
close the pop-up window, press the
ENT
key.
You can query the tool usage test with the
D18 ID975 NR1
function.
