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
Q326 Spacing in 1st axis? (incremental): Distance
between the first and second measuring points
in the reference axis of the working plane. Input
range 0 to 99999.9999
Q327 Spacing in 2nd axis? (incremental): Distance
between third and fourth measuring points in the
minor axis of the working plane. Input range 0 to
99999.9999
Q308 Corner? (1/2/3/4): Number identifying the
corner which the TNC is to set as preset. Input
range 1 to 4
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
Q304 Execute basic rotation (0/1)?: Definition of
whether the TNC should compensate workpiece
misalignment with a basic rotation:
0: Do not execute basic rotation
1: Execute basic rotation
Q305 Number in table?: Specify the row number
of the preset table/datum table to which the TNC
saves the coordinates of the corner; input range
0 to 9999. The TNC writes the entry to the preset
table or datum table depending on Q303:
Q303 = 1: The TNC writes to the preset table.
If the active preset is modified this change
immediately becomes effective. Otherwise an
entry is made in the specific row of the preset
table without automatic activation
