Abstract

Surface finish of materials is an essential subject for investigation since it impacts the quality of machined components. Nimonic C263 has a tremendous number of potential applications and is employed in the production of intricate components for gas turbines, aviation and automobiles. Nimonic alloys have mechanical qualities that make them difficult to produce with conventional techniques. For this, wire electrical discharge machining (WEDM) is often used, which just requires that the material being processed have appropriate electrical conductivity. The effect of machining parameters like Ton: Pulse on time, Toff: Pulse off time and Gap Voltage on surface roughness was investigated utilizing WEDM. Analysis of variance (ANOVA) is utilized in conjunction with a Taguchi-based experimental design to ascertain the significance of various factors and its level on surface roughness.
