The optimization of electrical discharge machining (EDM) parameters of Cobalt Chromium Molybdenum (Co-Cr-Mo) is performed using central composite design to improve the process efficiency in terms of increasing material removal rate and electrode utilization time. The effects of pulse on time, pulse off time, voltage and current on electrode wear rate (EWR) and material removal rate (MRR) have been examined. The experimental results indicate that higher pulse on time, lower pulse off time, 100 v to 110 v for voltage and current at the range of 8 to 9 A are the adequate selection to achieve higher MRR and lower EWR.

Abstract
The optimization of electrical discharge machining (EDM) parameters of Cobalt Chromium Molybdenum (Co-Cr-Mo) is performed using central composite design to improve the process efficiency in terms of increasing material removal rate and electrode utilization time. The effects of pulse on time, pulse off time, voltage and current on electrode wear rate (EWR) and material removal rate (MRR) have been examined. The experimental results indicate that higher pulse on time, lower pulse off time, 100 v to 110 v for voltage and current at the range of 8 to 9 A are the adequate selection to achieve higher MRR and lower EWR.Pubblicazioni consigliate
