Corner - right-angled corner (CYCLE961)

Function
This measuring variant can be used to measure a right-angled inside or outside corner of a
workpiece.
In addition to the measurement, the position of the corner can be used as workpiece zero in
a specified work offset (WO).
The measurements are performed paraxially to the machine coordinate system. Rotation of
the coordinates about Z is not taken into consideration. To traverse the probe parallel to the
edges to the corner to be measured, this must be achieved by means of corresponding angle
specifications in mask parameter α0.
Measuring principle
The measuring cycle moves to 3 measuring points and determines the point of intersection of
the resulting straight lines and the angle of rotation to the positive 1st axis of the actual plane.
The corner to be calculated can be offset.
The result, the position of the corner is saved as an absolute value in the result parameters
_OVR[ ] and optionally in the specified zero offset (offset and rotation). The measured corner
