Finite Element Analysis of Temperature Field in Vibration Milling
The purpose of this paper is to investigate the variation of temperature field of ultrasonic vibration assisted milling compared with that of conventional milling by FEM method. An equivalent two-dimensional finite element model was built to simplify the complexity of calculation. As results, the temperature field distribution, the variation of tool tip temperature and the change of heat generation rate in ultrasonic vibration assisted milling were analyzed compared with that in conventional milling process. According to analytical results, the application of ultrasonic vibration in milling process can significantly improve the distribution of cutting temperature, and reduce the impacts of thermal deformation and various thermal effects to cutting process.
