Programming example

1-angle measurement with CYCLE998
A rectangular workpiece (60 x 40 mm) is clamped in the G17 plane on a rotary table. The
intention is to orient it with its edges running parallel with axes X and Y.
An angular deviation detected is to be compensated automatically through additive ZO
compensation of the rotary axes. The maximum possible angular deviation is taken as _TSA
= 5°. The measuring path is programmed as _FA = 8 mm (max. total measurement path = 16
mm). The measuring points should be 40 mm apart. Intermediate positioning is to be at an
angle.
The rotary table is the 4th axis in the channel (C axis).
Clamping for workpiece:
Zero offset, with settable ZO G54: NVx, NVy, NVz, NVc
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.
