rection coefficients are used to
compensate for overall encoder
and machine travel variations. A
standard is measured, and the
measured value is compared to
the known value of the standard
to generate the correction co-
efficient. Correction coefficients are generated for each axis and
used in subsequent measurements to provide linear compensa-
tion for encoder variations.
