In the present global scenario, manufacturing industries are trying to make the process more sustainable by improving economic feasibility, machining efficiency, environment, and operator's safety as prescribed by ISO-14000 standards. The present study investigates the machining efficiency and sustainability analysis of the single wall carbon nano tube (SWCNT) mixed rotary electric discharge machining (EDM) process by utilizing waste vegetable oil (WVO) as a dielectric medium. Peak current, pulse on time, pulse off time, powder concentration, and tool rotation are taken as an input variable. The result reveals that SWCNT mixed rotary EDM utilizing WVO as a dielectric fluid exhibit 119.91% higher material removal rate (MRR) and 61.23% lower surface roughness (SR) as compared to the EDM process using EDM oil as a dielectric medium. Further, due to the superior thermo-physical properties of WVO, the proposed dielectric shows better surface morphology, lower recast layer thickness, better wear resistance, and low micro-hardness of machined surface as compared to EDM oil. Finally, the sustainability index analysis result concludes that WVO could be a better replacement of hydrocarbon-based oils in the EDM industry to make the process more sustainable in terms of cost, performance, ecological balance, and operator's safety.
