Tool usage test
The tool usage test function must be enabled by
your machine manufacturer. Refer to your machine
manual.
The tool usage test is not available for turning tools.
In order to be able to conduct a tool usage test, tool usage files
have to be generated, see page 618
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.
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:
Column Meaning
TOKEN 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
entries are listed in chronological order
TIMETOTAL: The total machining time
of the NC program is entered in the
WTIME column. In the PATH column
the TNC saves the path name of the
corresponding NC programs. The
TIME
column shows the sum of all
TIME
entries (feed time without rapid traverse
movements). The TNC sets all other
columns to 0
TOOLFILE: In the PATH column, the
TNC saves the path name of the tool
table with which you conducted the
Test Run. This enables the TNC during
the actual tool usage test to detect
whether you performed the test run
with the TOOL.T
