Calibrate probe - radius in ring (CYCLE976)

Function
Using this measurement version, the following data can be calibrated:
● Inclined position of the workpiece probe
● Trigger values
● Radius of the probe in a calibration ring (in axes of the plane)
The probe calibration in the ring can be on the basis of an unknown or known center point in
the ring. With known center point, this corresponds to the starting position.
Calibration is also possible taking into account a starting angle when using the "Start at ring
center" calibration method. Any obstacles in the measuring path or at the measuring point can
be avoided when using a starting angle.
Measuring principle
Calibration always starts in the positive direction of the 1st axis of the actual machining plane.
Eight calibration positions are to be acquired, divided into two passes. Depending on the probe
type, the passes are made with a uniform spindle position or a reversal of 180 degrees.
