Experimental investigation of effective parameters on productivity improvement of the EDM process for corrosion-resistant metals

Inconel 625 superalloy and stainless steel 304 are known for their significant corrosion resistance along with high hardness strength. Therefore, they used in a wide range of industries, including oil gas nuclear. Electrical discharge machining is among the most widely processes these metals. However, this process has limitations, such as low material removal efficiency, surface roughness, formation recast layer. study, effective parameters on increasing efficiency reducing layer thickness investigated. These include dielectric fluid, electrode material, current, pulse duration. After performing test matrix, effect each input rate, evaluated using ANOVA method. The results analysis showed that type fluid presence silver oxide nanoparticles have output variables. When sunflower containing electrode, roughness reduced, while average rate increases by 40% compared to traditional mode. Also, due biodegradability deionized water fluids, environmental sustainability study increased productivity, it leads sustainable development EDM process.
