Cycle parameters
U Center in 1st axis Q321 (absolute): Center of the hole
in the reference axis of the working plane. Input range
-99999.9999 to 99999.9999
U Center in 2nd axis Q322 (absolute value): Center of
the hole 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 (angle of the hole center). Input range
-99999.9999 to 99999.9999
U Nominal diameter Q262: Approximate diameter of
the circular pocket (or hole). Enter a value that is more
likely to be too small than too large. 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 -360.000 to 360.000
U Stepping angle Q247 (incremental): Angle between
two measuring points. The algebraic sign of the
stepping angle determines the direction of rotation
(negative = 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 -120.000 to 120.000
