Electrical Discharge Machining (EDM) is a non traditional machining and electro thermal process in which material from the workpiece is removed by using electrical discharges (sparks). It was first observed in 1770 by Joseph Priestley. He was an English physicist. In EDM machine the material is removed by rapidly recurring (repeating) discharges of current in between the electrodes.
Electro-Discharge Grinding. Electro-Chemical Grinding. EDG is not a hybrid process. ECG is one hybrid process. It is one thermal energy based non-conventional machining process. ECG is based on electro-chemical energy as well as mechanical energy. Here material removal takes place by melting and vaporization due to intense localized heat ...

the discharge area is very small like a single point [5]. In order to overcome the shortcoming of mechani-cal grinding, as well as enlarging the discharge area of WEDG, a WEDG process with line-segment wire discharge (called line-segment WEDG in this paper) was explored for machining the conical surfaces of needle valve seats. In the
crushing and grinding equipment breaks the materials into a random pattern from rocks, concrete and waste electric tools, and results in a high consumption of energy. Instead of conventional comminution methods, the technology of electrical disintegration (ED) using a lightning discharge impulse were investigated in this study.
