Machining characteristics of superalloy in EDM using nano particle suspended bio dielectric fluid

Abstract

Electrical Discharge Machining (EDM) is a well-founded newlinemachining option in the development of the manufacturing industry. It is newlineappropriate for extremely difficult for the processing, complex rigid material newlineparts by conventional machining processes. By using EDM, various kinds of newlineproducts can be manufactured like dies, molds. The automobile industry, parts newlineof aircraft, spacecraft and surgical components could be completely machined newlineby EDM. Recently, the mechanical industry has achieved an exponential newlineincrease in its production capacity but still, EDM is not used at their complete newlineefficiency. This limitation is a result of the failure to run the EDM optimally newlineoperating conditions. This research work is mainly concentrated on aspects newlinerelated to metal removal rates, which are one of the most essential newlinecharacteristics to select the optimal condition of the process and economic newlineaspect. The effect of process variables like response parameters like Surface newlineRoughness (SR) and Material Removal Rate (MRR), Surface morphology, newlinesurface Topography has been investigated by mixing of Biodegradable canola newlineoil methyl ester [COME], mixing Nano zirconium Oxide powder newlineindependently and blended with different concentration amount of zirconium newlinepowder values contain 0.5%, 1%, and 1.5% into the dielectric fluid for newlineelectric discharge machining of Hastelloy C276 utilizing copper is in the form newlineof electrode. In the present study, the model for output response which is used newlineto predict the material removal rate and surface roughness was developed by newlineutilizing RSM. The experimental result showed that the combination of newlinezirconium powder suspended in dielectric fluid considerably improved the newlineMRR reduces SR. The suspended powders in the dielectric fluid are highly newlineinfluencing the SR. As the MRR is high and the SR is not worsened, the newlineimprovement of surface roughness is not obvious in this condition. newline
