摘要：

Abrasive powder mixed Electrical discharge machining is a hybrid machining process providing both thermal and mechanical interactions. Addition of abrasive powders provides better discharge distribution along-with the abrasive action in dielectric. This paper analyses the effect of different parameters as Pulse on time, Pulse off time, Peak current and Gap voltage along-with the powder particle size and its concentration on MRR and SR while machining Inconel 718. SiC and Al2O3 powders are investigated here. Regression analysis has been done to model responses and then their optimization is performed through PSO. Finally, the betterment has been proved through confirmation experiments. (C) 2019 Elsevier Ltd. All rights reserved.
