17.6 MEASURE AXIS SHIFT (Touch Probe Cycle 440, DIN/ISO: G440)
Cycle parameters
U Operation: 0=calibr., 1=measure? Q363: Specify
whether you want to calibrate or make a verification
measurement:
0: Calibrate
1: Measure
U Probing directions Q364: Definition of probing
direction(s) in the working plane:
0: Measuring only in the positive direction of the
reference axis
1: Measuring only in the positive direction of the
minor axis
2: Measuring only in the negative direction of the
reference axis
3: Measuring only in the negative direction of the
minor axis
4: Measuring in the positive directions of the
reference axis and the minor axis
5: Measuring in the positive direction of the reference
axis and in the negative direction of the minor axis
6: Measuring in the negative direction of the
reference axis and in the positive direction of the
minor axis
7: Measuring in the negative directions of the
reference axis and the minor axis
U Setup clearance Q320 (incremental): Additional
distance between measuring point and probe
contact. Q320 is added to MP6540. Input range 0 to
99999.9999, alternatively PREDEF
U Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between tool
and workpiece (fixtures) can occur (referenced to the
active datum). Input range -99999.9999 to
99999.9999, alternatively PREDEF
