Abstract

One focus of this paper is to highlight issues on machining of discontinuously reinforced aluminium composites (DRACs), due to the complex deformation and interactions among particles, tool and matrix it is often unable to explore the behavior by an experimental or analytical method. This paper investigates the stress distribution in particles along, above and below cutting path under different cutting speed and constant depth of cut using finite element method. The development of stress fields in the DRACs was analyzed and physical phenomena such particle de-bonding, displacements and inhomogeneous deformation of matrix material were explored. It was found that tool-particle interaction and stress distributions in the particles/matrix are responsible for particle de-bonding and surface damage during machining of DRACs.
