Determination of the coordinates of an external corner of a workpiece
The coordinates of the external corner of a workpiece with unknown geometry are to be
determined.
Zero offset G55 is to be corrected in such a way that this corner is workpiece zero for G55.
The reference edge lies approximately at _STA1=-35 and the 2nd edge approximately at
_INCA= 80 degrees in addition. The distance to measuring points 2 and 4 is 100 mm.
The corner is to be passed over from P1 to P3 at distance _ID= 30 mm above measuring
height.
The starting point opposite the corner that is to be set up is reached before the measuring
cycle is called.
Workpiece probe 1, used as tool T9, D1, is
to be used.
The probe is already calibrated. Arrays for
workpiece probe 1: _WP[0, ...]
The following is entered under T9, D1 in
the tool offset memory:
Tool type (DP1):
Length 1 - geometry (DP3):
Radius - geometry (DP6):
Length 1 (L1) must refer to the center of the probe ball (_CBIT[14]=0), as for calibration.
Careful when positioning! Radius R in length (L1) is ignored.
