Method of determining geometric errors in a machine tool or measuring machine

摘要

A method of determining geometric errors in a machine tool or measuring machine having a mobile unit for moving a target within a measuring volume, the method including the steps of determining a first direction within the measuring volume; moving the target into a number of points along the direction by means of the mobile unit; measuring, by means of a measuring device, the abscissa of each of the points from an origin located along the first direction; acquiring the coordinates of each of the points by means of the machine; repeating the foregoing steps for a number of directions within the measuring volume; and determining error parameters of the machine on the basis of the abscissas measured by the measuring device, and the coordinates of the points acquired by the machine.
