Method and apparatus for determining the geometry of a workpiece in a forging press, fed into the forging press for processing in a processing throughpass and rotated about the longitudinal axis in predetermined manner. The surface of the workpiece is scanned over the periphery, in planes perpendicular to the direction of displacement of the workpiece. The data scanned are transmitted to a prepared programmed computer, and subsequently converted in the computer, with the aid of a program based on the condition of volume constancy, in such a way that the actual geometry of the workpiece is determined. The determined actual geometry is processed in the computer in such a way that a further deformation step, with predetermined programmed forging parameters, is initiated. The apparatus has a support in the shape of a ring, arranged in the vicinity of the processing region of the workpiece and on a mounting in such a way as to rotate around the workpiece at a determined speed. Installed on the inner surface of the ring are arranged adjacently, at two or more places, beam emitters and beam receivers for carrying out the scanning.
