Abstract
A coordinate measuring machine includes: a probe for measuring an object; a movement mechanism for moving the probe; and a motion controller for controlling the movement mechanism. The motion controller includes: a current value detecting unit that detects a current value for moving the probe by the movement mechanism; and a load judging unit that judges a status of a load applied on the movement mechanism based on the current value detected by the current value detecting unit and a threshold that is set in accordance with a target speed for moving the probe by the movement mechanism. The target speed is in proportion to the threshold.
