Touch Probe Cycles: Automatic Datum Setting
14.5 DATUM FROM OUTSIDE OF RECTANGLE (Cycle 411, DIN/ISO: G411)
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 secondary 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): 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?: Enter the number in the
datum/preset table in which the TNC is to save
the coordinates of the stud center. If Q303=1: If
you enter Q305=0, the TNC automatically sets the
display so that the new datum is on the stud center.
If Q303=0: If you enter Q305=0, the TNC writes to
line 0 of the datum table. Input range 0 to 99999
Q331 New datum 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 datum 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
