INVESTIGATION ON EDM OF SS316 ALLOY MATERIAL USING COPPER ELECTRODE FOR IMPROVING MRR AND TWR
Keywords:EDM, Parallelism, L9 Orthogonal Array
This paper demonstrates an investigation on Electro Discharge Machining of Stainless steel 316 using copper electrodes having different shape such as Square, Rectangle, Hexagon, Pentagon, Diamond. The essential input parameters are peak current, pulse on time, pulse off time and dielectric pressure due to these effect and the output parameters are Material removal rate (MRR), Electrode wear rate (EWR) and with tolerances namely Parallelism. This demonstration was carried out by L9 orthogonal array. This paper demonstrates that machining performance is improved effectively by EDM process.
