HEIDENHAIN iTNC 530 HSCI - Calibration Data; Multiple Probe Calibration Data Blocks

July 2013 8.13 Touch probe 1541
Calibration data The iTNC can save the calibration data for up to three touch probes at once:
 Set MP7490 bit 2 = 1.
 Use the traverse range switching function to activate the current data with
M4574/M4575.
 Specify with MP7411 bit 0 whether a probing block is to use the tool data
(length, radius, axis) from the last TOOL CALL block or from the calibrated data
of the touch probe. If MP7411 bit 0 = 1, you can use soft keys to take the
effective length and effective radius over into the tool table. Also, the tool
name and tool number of the touch probe are then displayed in manual
touch probe cycles.
 In the Manual and Electronic Handwheel operating modes, enter the tool
number in the menu for touch probe calibration.
MP7411 Tool data in the touch probe block
Input: Bit 0 –
0: Use the calibrated data of the touch probe
1: Use the current tool data from the last TOOL CALL
MP7490 Functions for traverse ranges
Format: %xxxx
Input: Bit 2 – Calibration data: touch probe for workpiece
measurement:
0: One set of calibration data for all traverse ranges
1: Every traverse range has its own set of calibration data

blocks
You can use the tool table to manage several blocks of touch probe calibration
data. Use the tool table columns CAL-OF1 (touch probe center offset in the
reference axis), CAL-OF2 (touch probe center offset in the minor axis) and CAL-
ANG (spindle angle when calibrating). In the standard setting, these columns
are hidden. They can be shown, however, with MP7266.28, MP7266.29 and
MP7266.30. The current touch probe calibration data can be viewed and
edited in the calibration menu for manual measurement:
 With MP7411 bit 1, activate the probe calibration management function in
the tool table. If bit 1 = 1, bit 0 has no function.
MP7411 Tool data in the touch probe block
Input: Bit 1 –
0: Only one set of touch probe calibration data
1: Use the tool table to manage more than one set of touch
probe calibration data
