Abstract

An electrochemical machining method and apparatus involves the passage of a wire through a programmably controllable electrochemical machine, wherein the wire is tapered along its length to obtain a desired profile. The rate of material removal may be determined, for example, by modulating the power supplied to the electrochemical machine, or by varying the wire speed therethrough. The machine can include an electrical contact cell and a nutation cell. Electrical power is coupled to the wire via the contact cell. Relative orbital motion of the wire and the nutating cell ensures that material removal from the wire is uniform in all directions.
