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. "Tool usage file"
The conversational 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.
Applying the tool usage test
Before starting a program in the Program Run mode of operation,
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 not visible unless the
machine parameter CfgPgmMgt/dependentFiles is set to MANUAL.
The generated tool usage file contains the following information:

TOOL: Tool usage time per TOOL CALL.
The entries are listed in chronological
order.
TTOTAL: Total usage time of a tool
STOTAL: Call of a subprogram; the

of the NC program is entered in the
WTIME column. In the PATH column
the TNC saves the path name of the

column shows the sum of all TIME
entries (without rapid traverse). The
TNC sets all other columns to 0
TOOLFILE: In the PATH column, the
TNC saves the path name of the tool
