u
p Calibrating the probing electrode
The probing electrode is to be calibrated in the following situations:
„ During commissioning
„
When the electrode is changed
„ When the probing feed rate is changed
„ In case of irregularities, such as those arising when the machine
heats up
During calibration, the TNC finds the effective length and the effective
radius of the electrode.
To calibrate the electrode, clamp a ring gauge of known height and
inside diameter to the machine table.
To calibrate the effective length:
8 Set the datum in the spindle axis such that for the machine tool table
Z=0.
8 Select the calibration function for the electrode length
(second soft-key row).
