Workpiece measurement in milling

Measuring in the "Program" operating area can be adapted corresponding to the specific
requirements using the channel-specific cycle setting data.

The following cycle setting data are written to by the measuring cycles with the "Calibrate
probe" measuring function. User parameterization is not necessary here. However, after the
probe has been calibrated, you can check these values and if required, evaluate the probe
quality, e.g. for position deviations, no values > 0.1 mm should be reached. Otherwise, the
probe must be mechanically readjusted.
The measuring feedrate at the time of calibration is used for all subsequent applications of
the measuring cycles.
Note
Observe the manufacturer's instructions for the probe.
