Metal matrix composites (MMCs) have been found to possess tremendous prospective engineering applications. These applications require materials offering a combination of lightweight with considerably enhanced mechanical and physical properties. However, the applications of MMCs are limited by their poor machinability. Due to highly nonlinear behaviour of MMCs and the complex relationship between deformation and temperature fields. The machining of MMCs is one of the important challenges in manufacturing process. Finite element method (FEM) is a powerful tool to predict the cutting process variables, which are difficult to obtain with experimental methods. In this paper, a quasi static Finite Element code was developed to investigate the mechanics of orthogonal cutting of a 6061Al-SiCp metal-matrix composite (MMCs).The FE code is based on the concepts of orthogonal cutting, chip separation criterion and Lagrange formulation without considering the temperature fields. A comparative study with the commercially available FEA software ANSYS shows the correctness of the developed code. The results show distribution of stress in machining of 6061 Al-SiC Metal matrix composites with SiC 15% by volume fraction and 25μm particle size when subjected to orthogonal cutting.
