Influence of ultrasonic vibration-assisted cutting on ploughing effect in cutting Ti6Al4V

Abstract

In this study, the finite element method (FEM) is used to study the ploughing effect of ultrasonic vibration-assisted cutting Ti6Al4V. Due to the existence of the cutting edge radius of the tool, there will be a ploughing area in the cutting of Ti6Al4V. The ploughing area is an area where the stress state is very complex in the cutting process. The ploughing force and temperature of the ploughing area are important factors that affect the machined surface quality and tool wear. The main research of this paper includes the establishment of ploughing force, temperature and dynamic friction coefficient model of the ploughing area, and the correctness of the analysis model is verified by using the finite element method. Then, by changing the cutting conditions, the influence of changing the cutting parameters on the ploughing effect is discussed. The results show that the analysis model can be used to monitor the ploughing force and ploughing area temperature, and ultrasonic vibration-assisted cutting can significantly reduce the ploughing force and ploughing area temperature, reducing tool wear and plastic deformation of the machined surface.
