摘要This article proposes an improved numerical model based on the coupled Eulerian-Lagrangian (CEL) formulation for the numerical analysis of metal cutting. Preliminary calculation results show that the model overcomes some shortcomings of traditional finite element (FE) models, for example, the mesh distortion and the limitation of the separation line method in the Lagrangian approach and setting the chip shape in advance in the Eulerian approach. Therefore, application of this model can provide a convenient simulation for stable and unstable cutting processes of metals and a vivid demonstration for the streamline field of plastic flow of a workpiece material during cutting. Moreover, it can accurately characterize the evolutions of stress, strain, and temperature fields in the chip, the variation histories of the cutting force with time and the shear-localized instability behaviors in the serrated chip. The simulation results have sufficiently demonstrated the potential of applying the CEL model to the numerical analysis of metal cutting. In particular, the CEL model facilitates the simulations of some special cutting processes, such as the machining of a vibrating workpiece and a thin wall component.
