Calibration, gauging block
A probe must be calibrated before it can be used. During calibration the triggering points
(switching points), positional deviation (skew), and precise ball radius of the workpiece probe
are determined and then entered in special data fields _WP[ ] in data block GUD6.DEF.
The default setting has data fields for 3 probes. Up to 99 are possible.
Calibration of the workpiece probe on turning machines is usually performed with gauging
blocks (reference grooves). The precise dimensions of the reference groove are known and
entered in the relevant data fields _KB[ ] in data block GUD6.DEF.
The default setting has data fields for 3 calibration bodies. The gauging block is selected in
the program with variable _CALNUM.
