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 reference point
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 reference point 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 reference point 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
No. of measuring points (4/3) Q423: Specify
whether the TNC should measure the hole with 4 or
3 probing points:
4: Use 4 measuring points (standard setting)
3: Use 3 measuring points
U
Type of traverse? Line=0/Arc=1 Q365: Definition of
the path function with which the tool is to move
between the measuring points if “traverse to
clearance height” (Q301=1) is active.
0: Move between operations on a straight line
1: Move between operations on the pitch circle
