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 2nd measuring point in 1st axis Q265 (absolute):
coordinate of the second touch point in the reference
axis of the working plane
8 2nd measuring point in 2nd axis Q266 (absolute):
coordinate of the second touch point in the minor axis
of the working plane
8 Measuring axis Q272: Axis in which the
measurement is to be made:
1: Reference axis = measuring axis
2: Minor axis = measuring axis
3: Touch probe axis = measuring axis
8 Traverse direction 1 Q267: Direction in which the
probe is to approach the workpiece:
-1: Negative traverse direction
+1: Positive traverse direction
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.
