Cycle parameters
Q273 Center in 1st axis (nom. value)? (absolute):
Center of the pocket 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 pocket in the secondary axis of
the working plane. Input range -99999.9999 to
99999.9999
Q282 1st side length (nominal value)?: Pocket
length, parallel to the reference axis of the working
plane. Input range 0 to 99999.9999
Q283 2nd side length (nominal value)?: Pocket
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): 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 pocket. Input range 0 to

Q286 Max. size limit 2nd side length?: Maximum
permissible width of the pocket. Input range 0 to
99999.9999
Q287 Min. size limit 2nd side length?: Minimum
permissible width of the pocket. Input range 0 to
99999.9999
Q279 Tolerance for center 1st axis?: Permissible
position deviation in the reference axis of the
working plane. Input range 0 to 99999.9999
Q280 Tolerance for center 2nd axis?: Permissible
position deviation in the minor axis of the working
plane. Input range 0 to 99999.9999
