Optimization study of hybrid aluminium metal matrix composite using proposed Taguchi method

Metal matrix composites (MMCs) are widely recognized as a dependable solution for fulfilling the requirements of engineering materials, including but not limited to mechanical properties, physical density, and outstanding resistance to wear. Al-alloy based metal matrix composites (AMMCs) have gained significant attention in both the aviation and automobile structural sectors due to their notable advantages in terms of performance, cost-effectiveness, and environmental sustainability. This research study focuses on the application of the Taguchi technique to forecast machining parameters for electrical discharge machining of an aluminum metal matrix composite added with 5 weight fraction of (B4C) and 6wt% of flyash. The L9 orthogonal array was developed in order to optimize the material removal rate (MRR) and surface roughness (RHA) by using the factors such as current, pulse on time, and pulse off time. The anticipated outcome was assessed through the utilization of analysis of variance (ANOVA).
