Please note while programming:
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
Danger of collision!
To prevent a collision between touch probe and
workpiece, enter a high estimate for the nominal diameter
of the stud.
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
The smaller the angle increment Q247, the less
accurately the TNC can calculate the datum. Minimum
input value: 5°.
