ABSTRACT

The development of new materials show the immense growth but the major problem, it is very difficult to machine the newly developed materials. So it is necessary to adopt some new machining methods. Electrical Discharge Machining (EDM) is a non-traditional and most popular machining method to manufacture dies, punches and press tools because of its capability to produce complicated, intricate shapes and to machine hard materials. From the industrial point of view, metal matrix composite is one of the main topics studied in the last 15 years. Having studied so long, this material is very suitable for use in several engineering applications, particularly in the automotive and aerospace [1]. The particle reinforced aluminium nitric MMC 10% is getting the attention of researchers because it has good properties in terms of high strength to weight ratio, high strength, high impact strength. During experimentation, current and pulse duration were taken as variables for the study of surface roughness and material removal rate. Cooper electrode is used with kerosene as a dielectric fluid in the experiment. Using Taguchi method, L9 orthogonal array has been chosen and three levels corresponding to each of the variables are taken. Experiments have been performed as per the set of experiments designed in the orthogonal array. Results of experimentation were analyzed analytically as well as graphically. Signal to Noise ratio was calculated to analyze the effect of input parameter more accurately. The optimal value of Surface Roughness (SR) and Material Removal Rate (MRR) were also calculated using their signal to noise ratio value. From the experimental results, it is clear that the cooper electrode with lowest current value (2amp) and pulse duration (4渭s) has better surface finish while highest current value (7amp) and pulse duration (8渭s) possess highest MRR.
