Cycle parameters
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
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
2nd meas. point 1st axis Q265 (absolute):
Coordinate of the second touch point in the
reference axis of the working plane. Input range
-99999.9999 to 99999.9999
2nd meas. point 2nd axis Q266 (absolute):
Coordinate of the second touch point in the minor
axis of the working plane. Input range -99999.9999
to 99999.9999
Measuring axis (1...3: 1 = principal axis) Q272:
Axis in which the measurement is to be made:
1 : Principal axis = measuring axis
2 : Secondary axis = measuring axis
3 : Touch probe axis = measuring axis
Traverse direction 1 Q267: Direction in which the
probe is to approach the workpiece:
-1 : Negative Traverse direction
+1 : Positive traverse direction
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
Set-up 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
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
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
