Investigating the Process Parameters of WEDM for Optimization on Die Steel EN-31 Using Taguchi-GRA Technique

Vikas Nandal

Abstract


Investigating the effect of heat treatment in industry, more focus was found on the use of optimization technique. The main aim of this process is to maximize of Hardness in of Steel material using Heat Treatment & Taguchi Method. EN31 is a manganese and chromium steel with high carbon content. EN31 is widely used in the automobile industry for making camshafts, shaft, pinion, heavy duty gear, gudgeon pins and machining components and many general engineering applications. The Experiment was conducted with a view to refer and research on Surface Roughness and Material Removal Rate. Experiment was carried out using three input parameters Pulse off time, Pulse on time and Wire Feed with three different levels. The effects of different input parameters and effect of their combination on Surface Roughness and Material Removal Rate was determined using Taguchi and ANOVA table.
