Cycle parameters
U 1st hole: Center in 1st axis Q268 (absolute):
Center of the first hole in the reference axis of the
working plane. Input range -99999.9999 to
99999.9999
U 1st hole: Center in 2nd axis Q269 (absolute):
Center of the first hole in the minor axis of the
working plane. Input range -99999.9999 to
99999.9999
U 2nd hole: Center in 1st axis Q270 (absolute):
Center of the second hole in the reference axis of the
working plane. Input range -99999.9999 to
99999.9999
U 2nd hole: Center in 2nd axis Q271 (absolute):
Center of the second 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
U Preset value for rotation angle Q307 (absolute): If
the misalignment is to be measured against a straight
line other than the reference axis, enter the angle of
this reference line. The TNC will then calculate the
difference between the value measured and the
angle of the reference line for the basic rotation.
Input range -360.000 to 360.000
