Abstract
A procedure for the numerically controlled processing of a workpiece on a grinding machine having a workholder for the workpiece as well as a wheelhead equipped with a grinding wheel, the wheelhead being pivoted on a wheelslide and able to be shifted together with the wheelslide in relation to the workholder, including detecting positions of a set of points situated within a working range of the grinding machine, covering coordinates of the set of points into basic data for a processing program of the grinding machine, and taking the basic data of the coordinates of the set of points into account while the workpiece is processed. A gauge is attached to the wheelhead and to a measuring device at a zero (M) of the machine, a spherical measuring head of the gauge presents a measuring point (IV) for detecting an initial position of the spherical measuring head in a coordinate system (X,Z) of the machine and coordinates of an existing position of the spherical measuring head are detected with the aid of the measuring device. A control unit enables an end position of the spherical measuring head to be detected where the measuring point (V) of the spherical measuring head would be if the …
