8 1st measuring point in 1st axis Q263 (absolute):
coordinate of the first touch point in the reference
axis of the working plane.
8 1st measuring point in 2nd axis Q264 (absolute):
coordinate of the first touch point in the minor axis of
the working plane.
8 Spacing in 1st axis Q326 (incremental): Distance
between the first and second measuring points in the
reference axis of the working plane.
8 Spacing in 2nd axis Q327 (incremental): Distance
between third and fourth measuring points in the
minor axis of the working plane.
8 Corner Q308: Number identifying the corner which
the TNC is to set as datum.
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
8 Execute basic rotation Q304: Definition of whether
the TNC should compensate workpiece misalignment
with a basic rotation:
0: No basic rotation
1: Basic rotation
