Calibrate probe - radius on surface (CYCLE973)

Function
With this measuring version, the radius of a workpiece probe with cutting edge positions
SL=5 to 8 can be calibrated on a surface. The trigger points of the probe are determined.
The calibration surface is workpiece-related. It is only possible to calibrate in the selected
axis and direction, which are perpendicular to this calibration surface.
Measuring principle
The determined switching position of the workpiece probe in the parameterized axis and
direction, is calculated with the setpoint of the reference surface and from this the
corresponding trigger point determined.
If no alarms occur, the trigger values are entered into the selected calibration data set of the
workpiece probe.
The probe travels in the measuring direction to the reference surface (e.g. workpiece)

Preconditions
● The surface must be in parallel to an axis of the workpiece coordinate system (WCS).
● The calibration surface must have a low surface roughness.
● The workpiece probe is called as tool with tool offset.
● 580 must be declared as the probe type.
Starting position before the measurement
The probe must be positioned opposite to the calibration surface.
