 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
 Set-up clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to MP6140. Input range 0 to 99999.9999,
alternatively PREDEF
 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, alternatively PREDEF
 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
Alternatively PREDEF
 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
 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
 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
 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 358).
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).
