Tool-Usage Test - HEIDENHAIN iTNC 530 HSCI Technical Manual

8.15.2 Tool-usage test

July 2013
When testing an NC program in the Test Run operating mode (calculate
machining time: active) or via an LSV2 command, a tool-usage file (*.T.DEP)
can be created automatically. It contains all required tools (number, index,
name, radius), the machining times (at 100% override) and their program calls.
Enable the function for generating the tool-usage file with MP7246 bit 2=1.

In the Program Run, Single Block and Program Run, Full Sequence operating
modes, press the TOOL USAGE TEST soft key to compare the data in the tool
usage file with the data in the tool table. If the tool-usage file is not current or
does not exist, the error message Generate tool usage file! appears.
Otherwise a pop-up window with the results of the comparison appears. The
value entered for TIME2 in the tool table must be at least 10% greater than the
time required.
In MP7485 a percentage value (0 to 100, default 10) can be entered for
application to the usage time found in the tool usage list. This makes it
possible to influence the selection if the selection of a tool depends on its
usage time. This machine parameter is also effective with the TOOL USAGE
TEST soft key in the Program Run, Full Sequence operating mode. Up to now,
a constant value of 10% was applied.
If MP7246 bit 4 is set, the calculation of the tool usage times is written to an
ASCII file. This file contains the run time and the absolute end time of each NC
block listed by NC block numbers. The name of the ASCII file is derived from
the name of the NC program (e.g. NCPROG.H) and has the extension
*.POS.DEP (e.g. NCPROG.H.POS.DEP).
