ABSTRACT:
Geometrical errors in a coordinate measuring machine are measured while works with various weights are mounted on the coordinate measuring machine. Compensation parameters are derived from measured results per a weight of a work and stored. A compensation parameter corresponding to a weight of a work to be measured is appropriately read out to correct measured coordinates of the work to be measured.
