One-dimensional and two-dimensional ultrasonic vibration cutting simulation of Ti6Al4V are carried out by the AdvantEdge FEM software and YG6X tool,and the effect of ultrasonic vibration parameters on residual stress is ana-lyzed.The simulation results show that the influence of vibration frequency and amplitude on the residual stress is not obvi-ous,and the maximum compressive stress and the depth of the compressive stress zone are not obvious.In one-dimensional Y-direction vibration,the smaller the vibration frequency is,the greater the residual compressive stress and the depth of the compressive stress zone is,the greater the vibration amplitude is and the residual compressive stress is,and the greater the depth of the compressive stress zone is.A1B1C3 is the best combination of two-dimensional vibration through range analy-sis.The influence of vibration parameters on residual stress is Ay＞(Fx,Fy)＞Ax.The conclusion is that ultrasonic vibra-tion cutting can increase the residual stress on the surface of the workpiece and improve the wear resistance and fatigue strength of the workpiece.
