A coordinate measuring machine has a coordinate measuring machine body and a controller. The coordinate measuring machine body has a probe having a measurement piece and a drive mechanism for driving the probe. The probe has a drive unit for driving the measurement piece. The controller includes a first measuring unit and a second measuring unit. The first measuring unit measures a displacement of the measurement piece driven by the drive unit. The second measuring unit measures a displacement of the probe. The measurement accuracy of the second measuring unit is lower than the measurement accuracy of the first measuring unit.
