Probe calibration
All probes must be mechanically correctly adjusted before use. The switching directions
must be calibrated before they are used in the measuring cycles for first-time. This also
applies when changing the stylus tip of the probe.
When being calibrated, the trigger points (switching points), position deviation (skew), and
active ball radius of the workpiece probe are determined and entered into the data fields of
the general setting data SD 54600 $SNS_MEA_WP_BALL_DIAM . There are 12 data fields.
Calibration can be realized in a calibration ring (known bore), on a calibration ball or on
workpiece surfaces, which have an appropriate geometrical precision and low surface
roughness.
Use the same measuring velocity for calibrating and measuring. This applies in particular to
the feedrate overide.
Measuring cycle CYCLE976 with different measuring versions is available to calibrate the
probe.
