Abstract
The variation in a machining process is reduced by Taguchi method through robust design of experiments. The primary objective of this method is to produce the parts with high quality at lower cost. Taguchi method is commonly used for optimizing the process parameters of a single objective problem but it results the non-optimum values for remaining. So that multi-characteristics response optimization will be the solution for optimizing the multi-responses. In the present work, multi objective optimization model based on Taguchi which is used to optimize process parameters, such as Pulse on, Pulse off and Peak Current on multiple performance characteristics, namely, Material Removal Rate (MRR), Tool Wear Rate (TWR) and Surface Roughness (Ra) during Electrical Discharge Drilling (EDD) of Inconel 718 using Copper tool. Design of experiments is a Taguchi approach which involves using orthogonal arrays to arrange the parameters which affect the process and the levels at which they should be varied. In this present work Taguchi’s L9 orthogonal array (OA) is selected for experimental planning and the experimental results showed that combination of higher levels of Pulse on, Pulse off and Peak Current are essential to achieve real-time maximization of MRR and minimization of TWR and SR and the results are analyzed by ANOVA.
