 Center in 1st axis Q321 (absolute value): Center of
the pocket in the reference axis of the working plane.
 Center in 2nd axis Q322 (absolute value): Center of
the pocket in the minor axis of the working plane.
 First side length Q323 (incremental value): Pocket
length, parallel to the reference axis of the working
plane.
 Second side length Q324 (incremental value): Pocket
length, parallel to the minor axis of the working plane
 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.
 Setup clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to MP6140.
 Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between tool
and workpiece (fixtures) can occur.
 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
 Datum number in table Q305: Enter the number in the
datum/preset 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 at the center of the pocket.
 New datum for reference axis Q331 (absolute):
Coordinate in the reference axis at which the TNC
should set the pocket center. Basic setting = 0
 New datum for minor axis Q332 (absolute):
Coordinate in the minor axis at which the TNC should
set the pocket center. Basic setting = 0
