Abstract: A method of electrochemical metal-removal. A metallic work tool having surface high-points and a metallic workpiece are each connected to a different terminal of a source of electrical energy, so that the workpiece and work tool can be used as the anode and cathode, respectively, of an electrolytic reaction. Relative movement is effected between the workpiece and the work tool in a first direction, associated with penetration of the work tool into the workpiece. Relative movement between the workpiece and the work tool is also effected in a second direction transverse to the first direction. An electrolyte is passed between and in contact with the work tool and the workpiece. A current flow is established between the work tool and workpiece and results in oxidation of the metal of the workpiece and the formation of high-points on the surface of the workpiece. At least intermittent contact is permitted between the work tool and the workpiece, in order to effect momentary shortcircuits between surface high-points on the work tool and surface high-points on the workpiece.
