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 wheelhead, which can be swivelled around a swivel axis (F), is swivelled through a specified angle, and the measuring point (V) passes through a patch (B). A check is performed to verify whether there is an discrepancy between an actual position of the spherical measuring head and the end position of the spherical measuring head.
