EDM is a process that high temperature is produced by direct electric discharge between work piece and electrode, and duplicate work piece under high temperature as per electrode shapes and accuracy. The work piece of EDM are usually with complicated shapes or high hardness which makes it difficult to mechanically machine.
EDM becomes necessary process in metal molds making industries currently.
