Cycle parameters

Q321 Center in 1st axis? (absolute): Center of the
stud in the reference axis of the working plane.
Input range -99999.9999 to 99999.9999
Q322 Center in 2nd axis? (absolute): Center of
the stud in the minor axis of the working plane.
Input range -99999.9999 to 99999.9999
Q323 First side length? (incremental): Stud
length, parallel to the reference axis of the working
plane. Input range 0 to 99999.9999
Q324 Second side length? (incremental): 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
Q305 Number in table?: Specify the row number
of the preset table/datum table to which the TNC
saves the coordinates of the center point; input
range 0 to 9999. The TNC writes the entry to the
preset table or datum table depending on Q303:
Q303 = 1:
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
Q303 = 0:
datum is not automatically activated
Q331 New preset in reference axis? (absolute):
Coordinate in the reference axis at which the TNC
should set the stud center. Default setting = 0.
Input range -99999.9999 to 99999.9999
Q332 New preset in minor axis? (absolute):
Coordinate in the minor axis at which the TNC
should set the stud center. Default setting = 0.
Input range -99999.9999 to 99999.9999
