Programming example 1

2-angle measurement with CYCLE998
(determining an oblique plane in space)
The task is to check the angular position of a machined oblique surface on a workpiece.
The result is taken from the result parameters _OVR[ ] for evaluation.
A measuring point 1 (P1) must be selected where P2 in the ordinate (with G17: Y axis) has
the same value as P1 and the abscissa value (_ID) is positive. P3 must still have the same
value in the abscissa (X axis in G17) as P1. The ordinate value (_SETV[0]) must be positive.
Positioning in the applicate must be performed as far as possible parallel with the oblique
plane (set angle).
The machined oblique plane has set angle about Y: 12 degrees (_INCA) and about X: 8
degrees (_STA1), maximum deviation _TSA= 5 degrees.
