Cycle run
Touch Probe Cycle 408 finds the center of a slot and defines its center
as datum. If desired, the TNC can also enter the coordinates into a
datum table or the preset table.
1 Following the positioning logic (see “Executing touch probe
cycles” on page 318), the TNC positions the touch probe to the
starting point 1 at rapid traverse (value from MP6150). The TNC
calculates the probe starting points from the data in the cycle and
the safety clearance from MP6140.
2 Then the touch probe moves to the entered measuring height and
probes the first touch point at the probing feed rate (MP6120).
3 Then the touch probe moves either paraxially at the measuring
height or linearly at the clearance height to the next starting point
2 and probes the second touch point.
4 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.
5 If desired, the TNC subsequently measures the datum in the touch
probe axis in a separate probing.
