Touch Probe Cycles: Automatic Measurement of Workpiece Misalignment | BASIC ROTATION over two holes

Cycle parameters

Q268 1st hole: center in 1st axis? (absolute):
Center of the first hole in the reference axis of
the working plane. Input range -99999.9999 to
99999.9999
Q269 1st hole: center in 2nd axis? (absolute):
Center of the first hole in the minor axis of
the working plane. Input range -99999.9999 to
99999.9999
Q270 2nd hole: center in 1st axis? (absolute):
Center of the second hole in the reference axis
of the working plane. Input range -99999.9999 to
99999.9999
Q271 2nd hole: center in 2nd axis? (absolute):
Center of the second hole in the minor axis of
the working plane. Input range -99999.9999 to
99999.9999
Q261 Measuring height in probe axis? (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
Q260 Clearance height? (absolute): coordinate in
the touch probe axis at which no collision between
tool and workpiece (fixtures) can occur. Input
range -99999.9999 to 99999.9999
Q307 Preset value for rotation angle (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
