Corner - right-angled corner (CYCLE961)

Function
This measuring variant can be used to measure a right-angled inside or outside corner of a
workpiece. The measurements are performed paraxially to the active workpiece coordinate
system.
In addition to the measurement, the position of the corner can be used as workpiece zero in
a specified work offset (WO).
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 work offset (offset and rotation). The measured corner
is shifted by the values in setpoint parameter (X0, Y0 for G17) in the workpiece coordinate
system in the plane.
