A Coordinate Measuring Machine, CMM, moving path adjustment assisting method that assists adjustment for a movement path of a probe in a coordinate measuring system, the coordinate measuring system comprising: a coordinate measuring machine that includes the probe having a probe tip at a tip thereof for detecting a surface of an object to be measured, and a movement mechanism for moving the probe, and measures a shape of the object to be measured by allowing the probe tip to scan the surface of the object to be measured; and a controller (40A, 40B) that controls operation of the coordinate measuring machine, the method comprising: calculating, by the controller (40A, 40B), a scanning path for allowing the probe tip to perform scanning movement along the surface of the object to be measured; calculating, by the controller (40A, 40B), the movement path followed by the probe when the probe tip moves along the scanning path; setting, by the controller (40A, 40B), control points on a line connecting each position of the probe tip on the scanning path and each position of the probe corresponding to each position of the probe tip; and accepting, by the controller (40A, 40B), a change in position of the control points by a user, and changing the movement path according to the change in position of the control points, wherein the controller (40A, 40B) provides adjustment guide means, and the method further comprises: moving collectively, by the controller, a plurality of control points upon the user utilizing the adjustment guide means. a coordinate measuring machine that includes the probe having a probe tip at a tip thereof for detecting a surface of an object to be measured, and a movement mechanism for moving the probe, and measures a shape of the object to be measured by allowing the probe tip to scan the surface of the object to be measured; and a controller (40A, 40B) that controls operation of the coordinate measuring machine, the method comprising: calculating, by the controller (40A, 40B), a scanning path for allowing the probe tip to perform scanning movement along the surface of the object to be measured; calculating, by the controller (40A, 40B), the movement path followed by the probe when the probe tip moves along the scanning path; setting, by the controller (40A, 40B), control points on a line connecting each position of the probe tip on the scanning path and each position of the probe corresponding to each position of the probe tip; and accepting, by the controller (40A, 40B), a change in position of the control points by a user, and changing the movement path according to the change in position of the control points, calculating, by the controller (40A, 40B), a scanning path for allowing the probe tip to perform scanning movement along the surface of the object to be measured; calculating, by the controller (40A, 40B), the movement path followed by the probe when the probe tip moves along the scanning path; setting, by the controller (40A, 40B), control points on a line connecting each position of the probe tip on the scanning path and each position of the probe corresponding to each position of the probe tip; and accepting, by the controller (40A, 40B), a change in position of the control points by a user, and changing the movement path according to the change in position of the control points, wherein the controller (40A, 40B) provides adjustment guide means, and the method further comprises: moving collectively, by the controller, a plurality of control points upon the user utilizing the adjustment guide means.
