Abstract

Using Python language to import Voronoi diagrams into ABAQUS, a two-dimensional microscopic model of vibration cutting of 45 steel is established, and based on this model, the stress changes of grains and grain boundary units on the cutting path are analyzed. The results show that in ultrasonic vibration cutting, the direction of normal stress and shear stress in the grain fracture unit will reverse, and the energy threshold will be reached during multiple impact processes, resulting in failure and deletion; During the impact process, grain boundaries are more prone to advanced failure under normal stress.
