Tool Usage Test - HEIDENHAIN TNC 620 User Manual

Tool usage test

The tool usage test function must be enabled by
your machine manufacturer. Refer to your machine
manual.
In order to be able to conduct a tool usage test, tool usage files
have to be generated.
Further Information: Tool usage file, page 583
The NC program has to be completely simulated in the Test Run
operating mode or executed in the Program Run, Full Sequence
or Single Block operating mode.
Using a tool usage test
Before starting a program in the Program Run operating mode,
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.
The TNC saves the tool usage times in a separate file with the
extension pgmname.H.T.DEP. This file is only visible when the
machine parameter dependentFiles (no. 122101) is set to MANUAL.
The generated tool usage file contains the following information:
