EDM (die-sink/wire-cut) is a process in which material is removed from the metal body with electricity.  Spark machining utilizes thermal erosion on the workpiece surface due to electrical sparking.


The advantage of the method is its precision and suitability for hardened materials. Very difficult shapes with demanding tolerances that cannot be done by milling can often be done by EDM.
