1) The document discusses the history, features, and benefits of wire electric discharge machining (Wire EDM). 2) Wire EDM is a non-traditional machining process that uses electric sparks to erode materials like ceramics, super alloys, and composites that cannot be cut with traditional tools. 3) The process involves an electrically charged wire tool and a workpiece separated by a dielectric fluid. Repeated electric sparks are generated between the wire and workpiece, vaporizing small amounts of material and creating the cut.
