Role of biodegradable dielectrics toward tool wear and dimensional accuracy in Cu-mixed die sinking EDM of Inconel 600 for sustainable machining

Abstract NetZero advancements for the manufacturing industry are aspiring precision machining of difficult-to-cut materials with a high degree accuracy, particularly Ni-based super alloys while meeting climate protocols. The applications and properties foregoing warrant usage electric discharge (EDM) technique. However, given rising scarcity resources, there is compelling need to make this process sustainable. standard dielectric (kerosene) employed in EDM hazardous one's health fails terms long-term productivity. As result, an effort has been made study evaluate potential biodegradable dielectrics, at different copper powder concentrations sustainable Inconel 600. This investigation evaluated three (0.5, 1.0, 1.5) g/100 ml each dielectric. Output responses including electrode wear rate overcut explicitly aid ensuring For example, EWR represents economic assessment, determines dimensional accuracy. full factorial design method was used experiments, followed by statistical examination encompassing, parametric effects interactions, signal-to-noise ratio. findings revealed decreased (2.69 mm 3 /min), as well minimal (0.33 mm). In case EWR, about 39% variation magnitude noted when dielectrics have varied, whereas approximately 30.9% observed against change concentration. overcut, influence on response further improved it produces 61% OC value. impact concentration 8%. It found that Amla oil 0.5 produced least tool wear, but Sunflower minimum (0.5 ml) overcut. combined effect all aforesaid strategies results more dimensionally accurate machining.
