Abstract: A method is provided to assist adjustment for a movement path of a probe. A coordinate measuring machine includes a probe having a tip for detecting a surface of an object, and a movement mechanism for moving the probe, and measures a shape of the object by allowing the probe tip to scan the surface. A controller controls operation of the coordinate measuring machine by calculating a scanning path for allowing the probe tip to perform scanning movement and the movement path followed by the probe when the probe tip moves along the scanning path, setting control points on a line connecting each position of the probe tip and each corresponding position of the probe accepting a change in position of the control points by a user, and changing the movement path accordingly. An adjustment guide unit in the controller allows the control points to move collectively.
