Effect of WEDM process parameters on surface roughness and waviness of inconel 603XL

Abstract

Inconel 603 XL alloys are high-temperature superalloys focused on nickel-chromium that are commonly used in aerospace, maritime, nuclear power generation; pharmaceutical, petrochemical, and process industries. In this work, the effect of process parameters of Wire Electrical Discharge Machining (WEDM) on Inconel 603 XL's surface roughness (SR) and waviness (Wa) was studied. The Taguchi analysis and the Desirability Function Analysis (DFA) carried out single objective optimization and multi-objective optimization. From the mean roughness of the surface and the measurement of waviness, pulse on time is among the other variables most important.
