Analysis of Cutting Speed and Surface Roughness Through WEDM Operation on E0300 Alloy Steel Using Anova

The paper presents the experimental investigation into the influence of WEDM parameters on cutting speed, upper and lower portion of machined surface roughness. The effect of cutting parameters on the machining characteristics are experimentally and theoretically investigated during machining of thick E0300 alloy steel by Electronica Sprintcut 734-WEDM. The basic aim of this investigation is to understand the effect of the machining characteristics on. cutting speed and surface roughness. Taguchi methods based L₁₈ mixed orthogonal array is used to determine S/N ratio and analysis of Variance and 'F' test values for indicating the significant parameters affecting the WEDM performance. The significant parameters are optimized and verified through confirmation from the seven selected reference setting parameters. Investigations were carried out considering the upper portion and the lower portion of the machined workpiece for the analysis of upper and lower surface roughness of anode and cathode. SEM results are also studied for the machined wire.
