Setting up a corner with definition of distances and angles

5.8.2.1

General information

Function
Using this measuring cycle and the _MVAR=105, _MVAR=106 measuring variants, the
internal and external corner of a rectangle can be measured and set up while using the
_MVAR=107, _MVAR=108 measuring variants, the internal and external corner of an
unknown workpiece geometry can be measured and set up.
The cycle approaches either 3 (for a rectangle) or 4 measuring points (if workpiece geometry
is not known) and calculates the point of intersection of the resulting straight lines and the
angle of rotation to the positive abscissa axis of the current plane. If the workpiece geometry
is known (rectangle), the corner to be calculated can be offset.
The result, the position of the corner, is stored as an absolute value in the specified ZO
(offset and rotation) and in the result parameters _OVR[ ].
The measuring points are derived from the specified angle and distances. Measurement is
performed paraxially to the existing workpiece coordinate system (WCS).
Note
When setting up the internal corner, the cycle only traverses in the plane at measuring
height.
When setting up the external corner, the corner can either be passed over using the shortest
path (lift in applicate) or traveled around in the plane.
