Abstract

Metal matrix composites (MMCs) present a high strength-to-weight ratio, superior wear resistance and mechanical properties. MMCs have been utilised in various industrial applications. In this work, a heterogeneous two-dimensional finite element model (FEM) was established to simulate microscale orthogonal machining of magnesium based MMCs reinforced with nano-sized SiC particles using ABAQUS/Explicit. The results present simulated chip formation process and local effect of particles during cutting process and it is observed to be different from that in conventional machining of MMCs with micro-sized particles. Finally, segmented chips with different geometry were observed in both circumstances.
