Effect of magnetic polarity on surface roughness during magnetic field assisted EDM of tool steel

Effect of magnetic polarity on surface roughness during magnetic field assisted EDM of tool steel

Electrical discharge machining (EDM) is one of the non-traditional machining techniques where the process offers wide range of parameters manipulation and machining applications. However, surface roughness, material removal rate, electrode wear and operation costs were among the topmost issue within...
