1552 HEIDENHAIN Technical Manual iTNC 530 HSCI
8.13.5 Tool measurement
With the HEIDENHAIN tool touch probes (TT) you can measure and inspect
tools. HEIDENHAIN provides standard cycles for automatic tool measurement
and calibration of the TT (see the Touch Probe Cycles User’s Manual).
Technical
prerequisites
You need:
 TT (TT 449/TT 140)
 Central tool file TOOL.T must be active (via machine parameter)
The iTNC can save the calibration data for up to three touch probes at once:
 Use the traverse range switching function to activate the current data with
M4574/M4575.
 Set MP7490 bit 3 to save three separate sets of calibration data.
MP7490 Functions for traverse ranges
Format: %xxxx
Input: Bit 3 – Calibration data: touch probe for tool measurement:
0: One set of calibration data for all traverse ranges
1: Every traverse range has its own set of calibration data
Standard
measuring cycles
The TT must be mounted and interfaced:
 With MP6500 bit 0, enable the cycles for tool measurement.
MP6500 Tool measurement with TT table touch probe
Format: %xxxxxxxxxxxx
Input: Bit 0 –
0: Cycles for tool measurement disabled
1: Cycles for tool measurement not disabled
Note
In the standard measuring cycles for tool measurement, the PLC program
may command a gear shift during output of the spindle speed without
interrupting the cycle.
