Cycle parameters

Q263 1st measuring point in 1st axis? (absolute):
Coordinate of the first touch point in the reference
axis of the working plane. Input range -99999.9999
to 99999.9999
Q264 1st measuring point in 2nd axis?
(absolute): Coordinate of the first touch point in
the minor axis of the working plane. Input range
-99999.9999 to 99999.9999
Q265 2nd measuring point in 1st axis?
(absolute): Coordinate of the second touch point
in the reference axis of the working plane. Input
range -99999.9999 to 99999.9999
Q266 2nd measuring point in 2nd axis?
(absolute): Coordinate of the second touch point
in the minor axis of the working plane. Input range
-99999.9999 to 99999.9999
Q272 Meas. axis (1/2/3, 1=ref. axis)?: 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
Q267 Trav. direction 1 (+1=+ / -1=-)?: Direction
in which the probe is to approach the workpiece:
-1: Negative traverse direction
+1: Positive traverse direction
Q261 Measuring height in probe axis? (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
Q320 Set-up clearance? (incremental): Additional
distance between measuring point and ball tip.
Q320 is added to SET_UP (touch probe table), and
is only effective when the preset is probed in the
touch probe axis. Input range 0 to 99999.9999
Q260 Clearance height? (absolute): coordinate in
the touch probe axis at which no collision between
tool and workpiece (fixtures) can occur. Input
range -99999.9999 to 99999.9999
