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): Define
an additional distance between measuring point
and ball tip. Q320 is added to SET_UP in the touch
probe table. 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
Q301 Move to clearance height (0/1)?: 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
Q312 Axis for compensating movement?: Define
with which rotary axis the TNC is to compensate
the measured misalignment:
0: Automatic mode—the TNC uses the active
kinematics to determine the rotary axis to be
aligned. In Automatic mode the first rotary axis of
the table (as viewed from the workpiece) is used
as compensation axis. Recommended setting.
4: Compensate misalignment with rotary axis A
