Comparison and research on simulation models of aluminum-based silicon carbide micro-cutting

This paper established three micro-cutting simulation models for SiCp/Al composites with a volume fraction of 45%. The three models of SiCp/Al composites, established by ABAQUS software, are equivalent homogeneous model, multiphase mixture model, and multiphase mixture cohesive model. And the three models were compared and analyzed. The results showed that the equivalent homogeneous model was suitable for studying the change of cutting force, stress flow, and cutting temperature with different cutting parameters. The multiphase mixture model could simulate the material removal during machining process and the prediction of machining surface defects. The multiphase mixture cohesive model, improved on the basis of the microscopic model, could better simulate the stress transfer and the debonding of SiC particles during machining process ensuring that the simulation results become more reasonable.
