The cold work applications like aluminium extrusion, it allows complex shapes to be formed with very smooth surfaces and it is popular for visible architectural applications such as window frames, door frames, roofs, and sign frames should have high toughness, wear resistance, compressive strength, high corrosion resistance, high surface finish and complex profiles. AA 6063 is an aluminium alloy, with magnesium and silicon as the alloying elements. This material can satisfy the above requirements, because of its hardness and strength AA 6063 cannot be machined easily through traditional machining processes. Advanced machining processes are used only when there is no suitable traditional machining process to meet necessary requirements efficiently and economically. Among them wire cut EDM is employed because of its tight tolerances and high surface finish. Based on intense literature survey, it was noticed that very few works were reported on WEDM of AA 6063. As a part of our thesis, WEDM of AA 6063 is considered for the study. In this work Pulse on time, pulse off time, peak current, wire speed, wire tension and flushing pressure of dielectric medium are considered as parameters and their effect on performance measures, metal removal rate MRR and surface roughness will be studied through experimental investigation. Using Taguchi approach, considered parameters will be optimized for maximum MRR and minimum for Surface roughness separately. Taguchi method will be applied to generate mean S N ratios to identify the optimum process parameters. Kandukuri Srinivas | K. Anabayan | P. H. J.
