16.8 Calibrating 3-D touch probes (option 17)
Introduction
In order to precisely specify the actual trigger point of a 3-D touch
probe, you must first calibrate the touch probe, otherwise the
control cannot provide precise measuring results.
Operating notes:
Always calibrate the touch probe again in the
following cases:
Initial configuration
Broken stylus
Stylus exchange
Change in the probe feed rate
Irregularities caused, for example, when the
machine heats up
Change of active tool axis
When you press the
OK
soft key after calibration,
the calibration values are applied to the active
touch probe. The updated tool data then become
immediately effective, there is no need to retrieve
the tool again.
During calibration, the control finds the effective length of the
stylus and the effective radius of the ball tip. To calibrate the 3-D
touch probe, clamp a ring gauge or a stud of known height and
known radius to the machine table.
The control provides calibration cycles for calibrating the length and
the radius:
