In the present days, automobile and aerospace sectors are showing more interest on aluminium metal matrix composites (AMMCs) due to their attractive properties. The machining of AMMCs by EDM is a field of attention for researchers as conventional machining of MMCs is complex and difficult. In this work, experiments are conducted on a composite sample of Al6101-Se/B4C/CNT called AMMC using EDM according to Taguchi experimental design for different parameter combinations such as electrode wire type, TON, TOFF, and peak current. The experimental data of machining responses such as surface roughness, material removal rate, and kerf width are measured for each experimental run. Further, the influence of process parameters on responses is studied by analysing them and optimal processes parameters are identified. Analysis of Variance is also employed for the identification of the order of influential process parameters on responses. This study provides ideal machining condition which can be utilized to increase material removal rate, as well as to limit surface roughness. Finally, the experimental results are validated through confirmation tests.

In this work, experiments are conducted on a composite sample of Al6101-Se/B4C/CNT called AMMC using EDM according to Taguchi experimental design for different parameter combinations such as electrode wire type, TON, TOFF, and peak current. The experimental data of machining responses such as surface roughness, material removal rate, and kerf width are measured for each experimental run. Further, the influence of process parameters on responses is studied by analysing them and optimal processes parameters are identified. Analysis of Variance is also employed for the identification of the order of influential process parameters on responses.
