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°.
