15.11 DATUM IN TOUCH PROBE AXIS
(Cycle 417, DIN/ISO: G417)
Cycle run
Touch Probe Cycle 417 measures any coordinate in the touch probe
axis and defines it as datum. If desired, the TNC can also enter the
measured coordinate in a datum table or preset table.
1 Following the positioning logic (see “Executing touch probe
cycles” on page 306), the TNC positions the touch probe to the
programmed starting point
1 at rapid traverse (value from MP6150
or MP6361). The TNC offsets the touch probe by the safety
clearance in the positive direction of the touch probe axis.
2 Then the touch probe moves in its own axis to the coordinate
entered as starting point
1 and measures the actual position with
a simple probing movement.
3 Finally the TNC returns the touch probe to the clearance height and
processes the determined datum depending on the cycle
parameters Q303 and Q305 (see “Saving the calculated datum”
on page 332) and saves the actual values in the Q parameters
listed below.

Before a cycle definition you must have programmed a
tool call to define the touch probe axis. The TNC then sets
the datum in this axis.
