Tool usage test
The following are prerequisites for a tool usage test:
„ Bit 2 of the machine parameter must be set to 7246=1
„ The machining timer must be active in the Test Run operating mode
„ A simulation of the plain language program must have been
completed in the Test Run mode
With the TOOL USAGE TEST soft key, you can check before starting
a program in a Program Run operating mode whether the tool being
used has enough service life remaining. Here the TNC compares the
actual values for service life in the tool table with the nominal values
from the tool requirement file.
After you have clicked the soft key, the TNC displays the results of the
tool usage test in a pop-up window. Use the CE key to close the pop-
up window.
The TNC saves the usage times in a separate file with the extension
pgmname.H.T.DEP
(see “Changing the MOD setting for dependent
files” on page 536). The generated tool usage file has the following
information:
The tool usage test function must be enabled by your
machine manufacturer. Refer to your machine manual.
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 (including
cycles); 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 (only when the spindle is on, and
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 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.
