Particle reinforced metal matrix composites have been widely used in automotive

aerospace and military and others fields due to their excellent properties such as high modulus

high strength and good wear resistance. However

in the cutting process of it

due to the presence of reinforced phase particles

the tool wear is serious

leading to the formation of debris and machined surface defects. Finite element simulation can realize the analysis of stripping and breakage of particle

and give the other microscopic details. It is an important supplement to the research of cutting experiment. In this paper

the research progress of three-dimensional finite element simulation of machining of particle reinforced composites is reviewed. The latest research of geometric model

interface model

constitutive model

meshing and boundary condition processing is introduced. The existing problems and development direction are discussed. The research results are helpful to promote the research of three-dimensional finite element simulation of cutting of particle reinforced composite

better reveal the cutting mechanism

and provide theoretical basis for the optimization of process parameter.
