8 Center in 1st axis Q273 (absolute value): Center of
the pocket in the reference axis of the working plane.
8 Center in 2nd axis Q274 (absolute value): Center of
the pocket in the minor axis of the working plane.
8 First side length Q282: pocket length, parallel to
the reference axis of the working plane.
8 Second side length Q283: pocket length, parallel to
the secondary axis of the working plane.
8 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.
8 Setup clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to column SET_UP.
8 Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between tool
and workpiece (fixtures) can occur.
8 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
