Cycle parameters

U

1st meas. point 1st axis Q263 (absolute): Coordinate

of the first touch point in the reference axis of the
working plane. Input range –99999.9999 to
99999.9999

U

1st meas. point 2nd axis Q264 (absolute):

Coordinate of the first touch point in the minor axis of
the working plane. Input range –99999.9999 to
99999.9999

U

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. Input
range –99999.9999 to 99999.9999

U

Setup clearance Q320 (incremental): Additional

distance between measuring point and ball tip. Q320
is added to SET_UP (touch probe table). Input range
0 to 99999.9999

U

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

U

Traverse direction 1 Q267: Direction in which the

probe is to approach the workpiece:
-1: Negative traverse direction
+1: Positive traverse direction

U

Clearance height Q260 (absolute): Coordinate in the

touch probe axis at which no collision between touch
probe and workpiece (fixtures) can occur. Input range
–99999.9999 to 99999.9999
