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
(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: -120,0000 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°.
