Abstract

Electric discharge machining is unconventional machining process used for machining of hard materials which cannot machined by conventional machining process. Electric discharge machining is an electro sparking method of metal working involving an electric erosion effect. A pulse discharge occurs in a small gap between the work piece and the electrode and removes the unwanted material from the parent metal through melting and vaporizing. In recent years, EDM researchers have explored a number of ways to improve EDM Process parameters such as Electrical parameters, Non-Electrical Parameters and Electrode based parameters. This new research shares the same objectives of achieving more efficient metal removal rate reduction in tool wear and improved surface quality. EDM technology is increasingly being used in tool, molds, dies, and in aerospace products and in surgical equipments making industries, for machining of advanced materials requiring high precision, complex shapes and high surface finish.
