Please note while programming:
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
Cycle parameters
U 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
U
Center in 2nd axis Q274 (absolute): Bolt hole circle
center (nominal value) in the minor axis of the working
plane. Input range -99999.9999 to 99999.9999
U Nominal diameter Q262: Enter the approximate
bolt hole circle diameter. The smaller the hole
diameter, the more exact the nominal diameter must
be. Input range 0 to 99999.9999
U 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
U 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
U Angle of 3rd hole Q293 (absolute): Polar coordinate
angle of the third hole center in the working plane.
Input range -360.0000 to 360.0000
U 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
-99999.9999 to 99999.9999
U Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between touch
probe and workpiece (fixtures) can occur. Input range
-99999.9999 to 99999.9999
