摘要: Cutting process of single abrasive grain was simulated by Smoothed Particle Hydrodynamics and Finite Element Method. Chip mechanism analyzed according to the stress variation workpiece material, motion situation smoothed particles in cutting layer. Effects rake angle depth on deformation material were also analyzed. It is concluded that occurs plastic deformation, flows side front owing extrusion grain, finally forms chip grain; capability increases with increase angle, it results protrusion rain relatively decrease beside force depth. Scratching experiment grains carried out using vitrified bonded CBN block. found laws simulation are consistent. proved correct, method feasible
