Abstract
A coordinate measuring machine includes: a probe that has a contact point capable of movement within a predetermined range; a movement mechanism for moving the probe; and a controller for controlling the movement mechanism. The controller has a measurement value calculating unit for calculating a position of the contact point based on a displacement of the movement mechanism and a displacement of the probe. The measurement value calculating unit includes: a correction parameter calculator for calculating a correction parameter for correcting the displacement of the probe based on a measurement condition in measuring an object; a corrector for correcting the displacement of the probe based on the correction parameter; and a displacement synthesizing unit that synthesizes the displacement of the movement mechanism and the displacement of the probe corrected by the corrector to calculate the position of the contact point.
