16.2 SLOT CENTER REF PT
(Cycle 408, DIN/ISO: G408)
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 The TNC positions the touch probe at rapid traverse (value from
FMAX column) following the positioning logic (see "Executing touch
probe cycles" on page 373) to the starting point 1. The TNC
calculates the touch points from the data in the cycle and the
safety clearance from the SET_UP column of the touch probe table.
2 Then the touch probe moves to the entered measuring height and
probes the first touch point at the probing feed rate (column F).
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 402) 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.
