A machining method typically used for hard metals, EDM makes it possible to work with metals for which traditional machining techniques are ineffective . Electrical-discharge-machineDesign for manufacturability ( also sometimes known as design for manufacturing or DFM ) is the general engineering art of designing products in such a way that they are easy to manufacture.

EDM is often included in the " non-traditional " or " non-conventional " group of machining methods together with processes such as electrochemical machining ( ECM ), water jet cutting ( WJ, AWJ ), laser cutting and opposite to the " conventional " group ( turning, grinding, drilling and any other process whose material removal mechanism is essentially based on mechanical forces ).
