Characteristics common to all touch probe
cycles for datum setting
Datum point and touch probe axis
From the touch probe axis that you have defined in the measuring
program the TNC determines the working plane for the datum:
415 DATUM INSIDE CORNER
Measuring two lines from the inside of a
corner, and defining the intersection as
datum Page 343
416 DATUM CIRCLE CENTER (2nd soft-
key row) Measuring any three holes on a
bolt hole circle, and defining the bolt-
hole center as datum Page 347
417 DATUM IN TS AXIS (2nd soft-key
row) Measuring any position in the touch
probe axis and defining it as datum Page 351
418 DATUM FROM 4 HOLES (2nd soft-
key row) Measuring 4 holes crosswise
and defining the intersection of the lines
between them as datum Page 353
419 DATUM IN ONE AXIS (2nd soft-key
row) Measuring any position in any axis
and defining it as datum Page 357
