U Probe in TS axis Q381: Specify whether the TNC
should also set the datum in the touch probe axis:
0: Do not set datum in the touch probe axis
1: Set datum in the touch probe axis
U Probe TS axis: Coord. 1st axis Q382 (absolute):
Coordinate of the probe point in the reference axis of
the working plane at which point the datum is to be
set in the touch probe axis. Only effective if Q381 =
1. Input range -99999.9999 to 99999.9999
U Probe TS axis: Coord. 2nd axis Q383 (absolute):
Coordinate of the probe point in the minor axis of the
working plane at which point the datum is to be set in
the touch probe axis. Only effective if Q381 = 1. Input
range -99999.9999 to 99999.9999
U Probe TS axis: Coord. 3rd axis Q384 (absolute):
Coordinate of the probe point in the touch probe axis,
at which point the datum is to be set in the touch
probe axis. Only effective if Q381 = 1. Input range
-99999.9999 to 99999.9999
U New datum in TS axis Q333 (absolute): Coordinate in
the touch probe axis at which the TNC should set the
datum. Default setting = 0. Input range: -99999.9999
to 99999.9999
U Set-up clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to SET_UP (touch probe table), and is only
effective when the datum is probed in the touch
probe axis. Input range 0 to 99999.9999
