Abstract: A method for electroerosive machining of metal workpieces and related apparatus. The erosion head of an electroerosive machining apparatus is moved with a blank clamped in it to a machining device for machining the blank with a machine tool held in the machining device, preferably a rotating milling tool the erosin head, and moves the blank for machining relative to machine tool as directed by a control computer. The machining device is located below the erosion head, with a vertical or horizontal axis of rotation, the electrode, following its manufacture, form the blank, is moved while still held by the erosion head to the electroerosive machining apparatus. Alternatively, an additional clamping device can be provided constructed like the erosion head for holding an electrode blank for machining by the machining device, while a workpiece is machined by electroerosion using an electrode held by the erosion head.

Abstract: The present invention relates to a method and an apparatus for the manufacture of dental prostheses by means of an electroerosion process by using two template electrodes for erosive excavation. The dental prosthesis to be inserted is made directly from solid material which has not been previously worked. The negative templates of the dental prosthesis contained in the template electrodes can also be made by the electroerosion method. The manufacture of the dental prosthesis can be accomplished by a simultaneous movement of the two template electrodes or by manufacture of the two form halves of the dental prosthesis at different times.
