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

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.

Investigation of white layer thickness, material removal rate, and tool wear rate of Inconel 718 by nano-Al2O3-mixed electrical discharge machining

“…Findings observed that a five g/l concentration of Si was the optimum parameter that produced 13.8 µm thickness of the white layer and 2.76 µm surface roughness. Ibrahim [10], investigated the influence of adding Al2O3 to the dielectric on MRR and SR to machine AISI 304 stainless steel. The results determined the appropriate parameters for machine AISI 304.…”

Improvement of Performance Evaluation Using Hybrid Composite Electrode (Cu/Cr/WC/Ag) in Electric Discharge Machining

“…The process involves the utilization of electrical discharges to erode material from a workpiece, making it a proficient approach for severing hard and brittle materials, which present challenges when subjected to traditional machining methods. The utilization of EDM for producing high-precision parts and components has been extensively adopted by various industries, including aerospace, medical, automotive, and electronics [2,3].…”
