are compared to the nominal values to generate correction coef-
ficients. Correction coefficients are generated for each segment
that deviates from the nominal value. The correction coefficients
are then used to provide linear compensation for only the seg-
ments requiring it.
Mount the standard on the stage and zero axes on the datum of
the standard. Measure and graph the
nominal and actual seg-
ment values as shown below. A segment is any group of points A segment is any group of points A segment is any group of points A segment is any group of points A segment is any group of points
