Influence of electrical discharge machining parameters by additives Nano [AL2O3] on surface roughness and material removal rate in machining of AISI 304

Abstract

Abstract Experimental investigation and optimization of machining parameters in electrical discharge machining (EDM) in terms adding particles Nano-reinforced among the various mechanical processes, the process of manufacturing in electrical discharge machines is one of the most effective and cost-efficient manufacturing processes in the manufacture of stainless steel. It has been dealt with in this article investigate each of operating parameters such as peak current (Ip), pulse on time (Pon) and pulse off time(Poff), insulating liquid with Nano powder (AL2O3) in EDM compounds AISI 304. In the present research work, the influences of certain process parameters on surface roughness(Ra) and material removal rate(MRR) were investigated on stainless steel carried out with powder mixture with particles size average of [5 nm]. Operating parameters are taking into consideration three factors based on the Taguchi method. The results from this work will be useful for manufacturing engineers to select appropriate set of process parameters to machine stainless steel.
