There are two ways to run a tool usage test for a pallet file:
If the cursor in the pallet file is on a pallet entry, the control runs
the tool usage test for the entire pallet.
If the cursor in the pallet file is on a program entry, the control
runs the tool usage test only for the selected NC program.
Using a tool usage test
Before starting a program in the
Program Run, Full Sequence/
Single Block
operating modes, you can check whether the tools
being used in the selected NC program are available and have
sufficient remaining tool life. The control then compares the actual
tool-life values from the tool table with the nominal values from the
tool usage file.
