CNC Wire Cut EDM Machining: A Comprehensive Guide
EDM (Electrical Discharge Machining) is a non-traditional metal machining process that uses spark erosion to remove material from the workpiece. An electrical discharge (spark) is created between an electrode, usually a wire, and the piece to be machined. There is typically a low conductive liquid medium between the two, such as deionized water, which is continually flushed as the work progresses.
