- Machining of particulate-reinforced metal matrix composites
- Pramanik, A.; Zhang, L. C.; Arsecularatne, J. A.
- The presence of hard reinforce particles in two phases materials, such as metal matrix composites (MMCs), introduces additional effects, such as tool-particle interactions, localised plastic deformation of matrix material, possible crack generation in the shear plane etc., over the monolithic material during machining. These change the force, residual stress, machined surface profile generation, chip formation and tool wear mechanisms. Additional plastic deformation in the matrix material causes compressive residual stress in the machined surface, brittle chips and improved chip disposability. Possible crack formation in the shear plane is responsible for low machining force and strength and higher chip disposability. Tool-particle interactions are responsible for higher tool wear and voids/cavities in the machined surface. This chapter presents the effects of reinforcement particles on surface integrity and chip formation in MMCs. The modelling of cutting is also discussed. Finally, tool wear mechanisms are described.
