U Traversing to clearance height Q301: Definition of
how the touch probe is to move between the
measuring points:
0: Move at measuring height between measuring
points
1: Move at clearance height between measuring
points
U Datum number in table Q305: Enter the number in
the datum/preset table in which the TNC is to save
the coordinates of the pocket center. If you enter
Q305=0, the TNC automatically sets the display so
that the new datum is at the center of the pocket.
Input range 0 to 2999
U New datum for reference axis Q331 (absolute):
Coordinate in the reference axis at which the TNC
should set the pocket center. Default setting = 0.
Input range -99999.9999 to 99999.9999
U New datum for minor axis Q332 (absolute):
Coordinate in the minor axis at which the TNC should
set the pocket center. Default setting = 0. Input range
-99999.9999 to 99999.9999
U Measured-value transfer (0, 1) Q303: Specify
whether the determined datum is to be saved in the
datum table or in the preset table:
–1: Do not use. Is entered by the TNC when old
programs are read in (see “Saving the calculated
datum” on page 314).
0: Write determined datum in the active datum table.
The reference system is the active workpiece
coordinate system.
1: Write determined datum in the preset table. The
reference system is the machine coordinate system
(REF system).
