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 318), the TNC positions the touch probe to the
programmed probe starting point
MP6150). 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
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 344) and saves the actual values in the Q parameters
listed below

Q160 Actual value of measured point
Please note while programming:
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.
