undamentals
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:
414 DATUM OUTSIDE CORNER
Measuring two lines from the outside of
the angle, and defining the intersection
as datum Page 336
415 DATUM INSIDE CORNER
Measuring two lines from within the
angle, and defining the intersection as
datum Page 341
416 DATUM CIRCLE CENTER (2nd soft-
key level) Measuring any three holes on
a bolt hole circle, and defining the bolt-
hole center as datum Page 345
417 DATUM IN TS AXIS (2nd soft-key
level) Measuring any position in the
touch probe axis and defining it as datum Page 349
418 DATUM FROM 4 HOLES (2nd soft-
key level) Measuring 4 holes crosswise
and defining the intersection of the lines
between them as datum Page 351
419 DATUM IN ONE AXIS (2nd soft-key
level) Measuring any position in any axis
and defining it as datum Page 355

You can also run the Touch Probe Cycles 408 to 419 during
an active basic rotation.
The tilting the working plane function is not permitted in
combination with Cycles 408 to 419.
