Abstract
WEDM is a one of the non-traditional machining processes used for machining complex shape components and hard materials like composites and inter-metallic materials. This paper presents the optimization of wire electrical discharge machining (WEDM) process parameters such as pulse on time (Ton), pulse off time (Toff) and wire tension (WT) to yield maximum material removal rate (MRR) and minimum surface roughness (Ra) of copper. The machining experiments were carried out according to the Taguchi parametric design (L9) using 0.25 mm diameter brass wire as a cutting tool. Analysis of variance (ANOVA) was used to find the significance of each process parameter. Optimal results have been verified through confirmation experiments. In addition, the regression equations were also established between the process parameters and responses. The results indicate that pulse on time is the most significant factor influencing the MRR and Ra followed by pulse off time and wire tension.
