1st measuring point in 1st axis

Q263 (absolute):

coordinate of the first touch point in the reference
axis of the working plane.

1st measuring point in 2nd axis

Q264 (absolute):

coordinate of the first touch point in the minor axis of
the working plane.

Spacing in 1st axis

Q326 (incremental): Distance

between the first and second measuring points in the
reference axis of the working plane.

Spacing in 2nd axis

Q327 (incremental): Distance

between third and fourth measuring points in the
minor axis of the working plane.

Corner

Q308: Number identifying the corner which

the TNC is to set as datum.

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

Execute basic rotation

Q304: Definition of whether

the TNC should compensate workpiece misalignment
with a basic rotation:
0: No basic rotation
1: Basic rotation
