Electrical Discharge Machining (EDM) wire cutting uses a metallic wire to cut out a programmed predetermined form out of a part. Dies used for extrusions are commonly machined using wire cutting. Before machining it is important to decide whether we need to start from a drilled hole or from an edge of material.

On the area that is being machined, the discharge from the machining creates a crater and this will impact on the tool. The wire can also be angled, which makes it possible to taper parts or create different profiles at the top and bottom. The wire itself is made usually of a metal such as brass or stratified copper and sits between 0.1 – 0.3 mm in diameter.
