Cycle parameters
U Center in 1st axis Q321 (absolute): Center of the stud
in the reference axis of the working plane. Input range
-99999.9999 to 99999.9999
U Center in 2nd axis Q322 (absolute): Center of the
stud in the minor axis of the working plane. If you
program Q322 = 0, the TNC aligns the hole center to
the positive Y axis. If you program Q322 not equal to
0, then the TNC aligns the hole center to the nominal
position. Input range -99999.9999 to 99999.9999
U Nominal diameter Q262: Approximate diameter of
the stud. Enter a value that is more likely to be too
large than too small. Input range 0 to 99999.9999
U Starting angle Q325 (absolute): Angle between the
reference axis of the working plane and the first touch
point. Input range -360.0000 to 360.0000
U Stepping angle Q247 (incremental): Angle between
two measuring points. The algebraic sign of the
stepping angle determines the direction of rotation
(- = clockwise) in which the touch probe moves to the
next measuring point. If you wish to probe a circular
arc instead of a complete circle, then program the
stepping angle to be less than 90°. Input range
-120.0000 to 120.0000
U Measuring height in the touch probe axis Q261
(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
U Setup clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to SET_UP (touch probe table). Input range
0 to 99999.9999
U Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between touch
probe and workpiece (fixtures) can occur. Input range
-99999.9999 to 99999.9999
U Traversing to clearance height Q301: 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
U Datum number in table Q305: Enter the datum
number in the table in which the TNC is to save the
coordinates of the pocket center. If you enter
Q305=0, the TNC automatically sets the display so
that the new datum is on the stud center. Input range
0 to 2999
