Cycle parameters

Q273 Center in 1st axis (nom. value)? (absolute):
Center of the stud in the reference axis of the
working plane. Input range -99999.9999 to
99999.9999
Q274 Center in 2nd axis (nom. value)?
(absolute): Center of the stud in the minor axis
of the working plane. Input range -99999.9999 to
99999.9999
Q282 1st side length (nominal value)?: Stud
length, parallel to the reference axis of the working
plane. Input range 0 to 99999.9999
Q283 2nd side length (nominal value)?: Stud
length, parallel to the minor axis of the working
plane. Input range 0 to 99999.9999
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
Q284 Max. size limit 1st side length?: Maximum
permissible length of the stud. Input range 0 to
99999.9999
Q285 Min. size limit 1st side length?: Minimum
permissible length of the stud. Input range 0 to
99999.9999
