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
