EDM is not a production line technique since workpiece removal rates are extremely small compared to conventional machining. But in those situations where either the (intricate) configuration or (super hard) material is difficult to machine by traditional methods, EDM has pronounced advantages. The mechanical forces on the EDM electrode and spindle are only a small fraction of those generated in traditional cutting. EDM is both simple enough and inexpensive enough that many mould and die shops are using it.
