There has been a critical need for development of cost-effective aluminum (Al) based metal matrix composites (MMCs) for various industrial applications. But hither to no work has been reported for process capability analysis of Al based MMC prepared by combining fused deposition modelling (FDM), vacuum moulding and stir casting process. In the present work an approach to macro-model the hardness of Al based MMC have been proposed and applied for process capability analysis. The relationship between hardness and other input parameters have been deduced by using Taguchi technique L9 orthogonal array. The result of study indicate that value of process capability indices is greater than 1 for the MMC developed by combining FDM, vacuum moulding and stir casting process. Hence the process can be used for commercial batch production activities.
