Skewing the part
Accurate measurements require the part to be perfectly aligned on the coordi-
nate measuring system. An imperfectly aligned part yields inaccurate measure-
ments. Use the skew function to convert machine coordinates to part coordi-
nates and compensate for part misalignment. Measure a skew each time a new
part is mounted on the measuring system.
Measure a skew line by probing a straight edge of known orientation. Use a
minimum of 2 points and a maximum of 100 when probing the line. Remem-
ber that more points means greater accuracy.
Construct a skew line from previously measured features. For example, con-
struct a skew line using two circles. Keep in mind that the more points probed
on features used in the construction of a skew line, the greater the accuracy.
