Abstract

© 2018, Springer-Verlag London Ltd., part of Springer Nature. This paper investigates the underlying cutting mechanism of SiC particle-reinforced aluminum matrix composites (MMCs) using finite element (FE) simulations and precision turning experiments. One constitutive model for SiCp/Al composites is established and verified by experiments. On this basis, the possible fracture processes of SiC particles in turning process are studied, and three types of fracture are finally found. The types and the corresponding formation mechanism of machined surface defects are investigated; the relationship between the particle size and surface roughness is established quantitatively. Furthermore, the influences of machining parameters on the cutting force are studied. The proposed FE simulation model and conclusion are verified by precision turning experiments.
