Wire EDM

Wire EDM, or Wire Electrical Discharge Machining, is a precise cutting method that uses a thin, electrically charged wire to cut intricate shapes through conductive materials. It works by creating sparks that erode the material.

TECHNICAL DEFINITION

Wire Electrical Discharge Machining (WEDM) is a non-contact thermal manufacturing process that uses a continuously fed, thin, electrically charged wire electrode to erode conductive materials via controlled electrical discharges (sparks), producing complex 2D and 3D geometries. Key entities: wire electrode, electrical discharge, conductive materials, thermal process.

BACKGROUND

Electrical discharge machining (EDM), also sometimes known as spark machining or spark eroding, is a metal cutting process whereby a desired shape is obtained by using electrical discharges (sparks). Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. One of the electrodes is called the tool electrode, while the other is called the workpiece electrode, or workpiece. The electrode can be in any of several forms: when it is a wire, it is well suited to cutting a thin kerf, and the process is called wire EDM ; when it is a block with a shape cut into it, it is well suited to diesinking and is called diesinking EDM. The process depends upon the tool and workpiece not making physical contact. Extremely hard materials like carbides, ceramics, titanium alloys and heat treated tool steels that are very difficult to machine using conventional machining can be precisely machined by EDM.
