<p>This study evaluates the potential of corn biodiesel (BD) as an alternative dielectric fluid in electrical discharge machining (EDM). Corn BD was synthesized through a transesterification process involving corn oil and methanol, catalyzed by sodium hydroxide. The performance of eco-friendly dielectric fluids (corn BD and synthetic oil) was compared to conventional dielectric fluids (kerosene and transformer oil) in terms of total machining time, tool wear rate (TWR), and surface roughness (SR).

摘要

This study evaluates the potential of corn biodiesel (BD) as an alternative dielectric fluid in electrical discharge machining (EDM). Corn BD was synthesized through a transesterification process involving corn oil and methanol, catalyzed by sodium hydroxide. The performance of eco-friendly dielectric fluids (corn BD and synthetic oil) was compared to conventional dielectric fluids (kerosene and transformer oil) in terms of total machining time, tool wear rate (TWR), and surface roughness (SR). EDM experiments were conducted using copper electrodes to machine aluminum alloy workpieces. The machined surfaces were characterized using white light interferometry (WLI) to evaluate their surface topography and scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM–EDS) to understand its surface characteristics. The results demonstrated that corn BD significantly reduced TWR by 63% and 42%, and SR by 67% and 18%, compared to kerosene and transformer oil, respectively. Additionally, corn BD enabled a 43% reduction in machining time compared to synthetic oil. ANOVA analysis confirmed the statistically significant impact of corn BD on TWR and SR, validating its efficacy as a dielectric fluid. Furthermore, the use of corn BD contributes to environmental sustainability by reducing hazardous emissions. This establishes a viable and eco-friendly alternative for EDM applications.
