ABSTRACT:
A method of restoring a wire electrode which has been broken during an electric discharge machining operation. A new wire electrode, which replaces the broken wire electrode, moves from an initial machining point to an electrode breaking point with the application of a voltage between a workpiece and the wire electrode to generate an electric discharge therebetween resulting in smooth movement of the electrode.
