Role of Magnetic Field Assistance in Electric Discharge Machining

  • Aman Kumar Professor, Mechanical Engineering Department, IET Bhaddal Technical Campus, Ropar, Punjab, India.


Electric discharge machining is an excellent culminating process that utilizes magnetic-field support and provides amended machining performance with both a high material removal rate and capable of excellent machining capacity of all involute geometries thus find wide applications in many industries including aero, automobile, medical, etc. This paper presents a basic review of the effect of magnetic field assistance in the electric discharge machining process (MFAEDM) and enlightens on how magnetic field assistance enhances the machining output/ efficiency of EDM.
