3.1 Measuring Workpiece Misalignment

8 First hole: Center in 1st axis Q268 (absolute):

center of the first hole in the reference axis of the

working plane.

8 First hole: Center in 2nd axis Q269 (absolute):

center of the first hole in the minor axis of the working

plane.

8 Second hole: Center in 1st axis Q270 (absolute):

center of the second hole in the reference axis of the

working plane.

8 Second hole: Center in 2nd axis Q271 (absolute):

center of the second hole in the minor axis of the

working plane.

8 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.

8 Clearance height Q260 (absolute): Coordinate in the

touch probe axis at which no collision between tool

and workpiece (fixtures) can occur.

8 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.
