Optimization of Multiple Input Process Parameters of WEDM on Titanium Ti 6Al-4v (Grade 5) By Taguchi Analysis

Abstract

The experimental study is about the optimizing the cutting process parameters of the WEDM (Wirecut Electric Discharge Machining) during the machining of Titanium Ti 6Al-4V (Grade 5) material. The high strength and high hardness of Titanium Ti 6Al-4V (Grade 5) alloy offers a challenging task in obtaining a better surface finish and Material Removal Rate. The material removal rate and the surface roughness of Titanium Ti 6Al-4V (Grade 5) is carried out and an excellent machined surface can be obtained by the setting the machining parameters at optimum level by various experimental study of material while machining in WEDM. The machining parameters such as Pulse ON time (TON), Pulse OFF time (TOFF), Gap Voltage (GV) and Wire Feed Rate (WFR) used as input parameters to attain optimum output responses like Material Removal Rate(MRR) and surface roughness using Taguchi’s DOE approach. In this present work, 9 Experiments were conducted for 4 inputs Parameter and 3 levels for each Input parameter and the experimental results of MRR were analysed using Taguchi method. From the Signal to Noise ratio values of MRR, the optimum levels of selected Input Process Parameter were found successfully.
