Electrical Discharge Machining

Electrical discharge machining, or EDM, shapes metal by creating sparks that melt tiny portions of the workpiece, and is an exceptionally diverse process that generates no cutting forces. EDM is especially useful in the production of fragile parts that cannot take the stress of conventional machining. Part of SME’s Fundamental Manufacturing Processes video series, this program examines the EDM process, and the two primary forms of electrical discharge machining, Ram EDM, and wire EDM Process segme
