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
Setup clearance
Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to MP6140. Input range 0 to 99999.9999,
alternatively PREDEF
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, alternatively PREDEF
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
Alternatively PREDEF
U
Datum number in table
Q305: Enter the datum
number in the 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 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 344).
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).
