TNC 620 | User's Manual Cycle Programming | 3/2014
Please note while programming:
Before a cycle definition you must have programmed
a tool call to define the touch probe axis.
Cycle 430 only monitors for tool breakage; there is
no automatic tool compensation.
Cycle parameters
Center in 1st axis Q273 (absolute): Bolt hole circle
center (nominal value) in the reference axis of
the working plane. Input range -99999.9999 to
99999.9999

circle center (nominal value) in the minor axis of
the working plane. Input range -99999.9999 to
99999.9999
Nominal diameter Q262: Enter the bolt hole circle
diameter. Input range 0 to 99999.9999
Angle of 1st hole Q291 (absolute): Polar coordinate
angle of the first hole center in the working plane.
Input range -360.0000 to 360.0000
Angle of 2nd hole Q292 (absolute): Polar coordinate
angle of the second hole center in the working
plane. Input range -360.0000 to 360.0000

angle of the third hole center in the working plane.
Input range -360.0000 to 360.0000
Measuring height in the touch probe axis Q261
(absolute): Coordinate of the ball tip center (=
touch point) in the touch probe axis in which
the measurement is to be made. Input range
