326 Touch Probe Cycles: Automatic Measurement of Workpiece Misalignment
14.3 BASIC ROTATION from Two Holes (Cycle 401, DIN/ISO: G401)
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, alternatively PREDEF
U Default setting for basic rotation 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
