U Measuring height in the touch probe axis Q261
(absolute): Coordinate of the ball tip center (= touch
point) in the touch probe axis in which the
measurement is to be made. 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). Input range
0 to 99999.9999
U
Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between touch
probe and workpiece (fixtures) can occur. Input range
-99999.9999 to 99999.9999
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 stud center. If you enter
Q305=0, the TNC automatically sets the display so
that the new datum is on the stud center. 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 stud 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 stud 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).
