An investigation into the parametric optimization of al 2219 using CNC wire EDM by using taguchi method

Abstract

Optimization is one of the techniques used in manufacturing fields to arrive for the best manufacturing conditions, and essential need for industries for production of good products at cheap cost. This paper aims to investigate the optimal set of process parameter such as pulse on time, pulse off time and peak current in wire electrical discharge machining (WEDM) process to identify the variation in performance characteristic such as material removal rate (MRR) and surface roughness (Ra) value on the work material for machining Aluminium 2219 using brass electrode. Based on the experiment conducted on L9 orthogonal array, analysis has been carried out using ANOVA and Taguchi method. Response table and graphs were used to find the optimal levels of parameters in WEDM process. The confirmation experiments were done to validate the better results.
