It has been effectively used for the machining of the complex shape work piece which is not easy to machine under silple EDM process. The basic principle of working hybrid-machining processes is to combine the advantages of different advanced machining processes to avoid or reduce the adverse effects of the constituent processes. Advanced Machining processes have been divided according to the energy used for the machining of the work materials i.e. Mechanical, Thermal and Chemical. The Ultrasonic machining(USM), Water jet machining(WJM), and Abrasive jet machining (AJM) come under mechanical, Electrical discharge machining(EDM), Electron beam machining(EBM), Laser beam machining(LBM) under thermal, and Chemical machining(CHM), Photo chemical machining(PCM) under chemical energy . In EDM process electric energy is converted into thermal energy for material removal action by melting and evaporation. Copyright@ International Science Community Association
