Cycle parameters
U First center in 1st axis Q268 (absolute): center of
the 1st hole in the reference axis of the working
plane. Input range –99999.9999 to 99999.9999
U First center in 2nd axis Q269 (absolute): center of
the 1st hole in the minor axis of the working plane.
Input range –99999.9999 to 99999.9999
U First center in 1st axis Q270 (absolute): center of
the 2nd hole in the reference axis of the working
plane. Input range –99999.9999 to 99999.9999
U First center in 2nd axis Q271 (absolute): center of
the 2nd hole in the minor axis of the working plane.
Input range –99999.9999 to 99999.9999
U First center in 1st axis Q316 (absolute): center of
the 3rd hole in the reference axis of the working
plane. Input range –99999.9999 to 99999.9999
U 3rd center in 2nd axis Q317 (absolute): center of
the 3rd hole in the minor axis of the working plane.
Input range –99999.9999 to 99999.9999
U 4th center in 1st axis Q318 (absolute): center of
the 4th hole in the reference axis of the working
plane. Input range –99999.9999 to 99999.9999
U 4th center in 2nd axis Q319 (absolute): center of
the 4th hole in the minor axis of the working plane.
Input range –99999.9999 to 99999.9999
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
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
