8 First measuring point in the 1st axis Q263
(absolute): Coordinate of the first touch point in the
reference axis of the working plane.
8 First measuring point in the 2nd axis Q264
(absolute): Coordinate of the first touch point in the
minor 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 Measuring axis (1..3: 1=reference 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 Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between tool
