3.3 Automatic Workpiece Measurement

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

and workpiece (fixtures) can occur.
