Abstract
The electrical discharge machining removes workpiece by an electrical spark erosion process. The variations in the machining parameters, such as polarity, pulse-on time, open discharge voltage, discharge current and dielectric fluid greatly affect the measures of the machining performance, for example surface roughness, EWR and MRR. Therefore, proper selection of the machining parameters can result in better machining performance. The surface phenomena that occur by EDMed were studied under different machining parameter. The machining parameters selected are current, voltage and jump speed. Experimental result indicate that the higher the discharge energy, the faster the machining time which will influences the resolidified surface layer and worsens the surface roughness.
