Operational sequence

Defining distances and angles
Position before measuring cycle call
The probe is positioned at measuring depth opposite the corner to be measured. It must be
possible to approach the measuring points from here without collision. The measuring points
are derived from the programmed distance between the starting point and
_SETVAL[0] (measuring point 2) or
_SETVAL[1] (meas. point 4) in direction of angle _STA1, _INCA.
The starting points for measuring point 1 and 3 are each located at half the distance.
Measurement is performed paraxially with the existing workpiece coordinate system.
_STA1 refers to the machine coordinate system.
The measuring cycle generates the required traversing blocks and performs the
measurements at the measuring points.
During travel an additional tolerance angle of 10 degrees is added to the programmed
angles in the cycle.
First measuring point P 2, then P 1, P 3, and depending on parameterization, P 4 is
approached.
