ABSTRACT
This paper presented the elliptical vibration turning (EVT) and conventional turning (CT) process of high-strength aluminum alloy material Al7050-T7451 by establishing the finite element models. The characteristics of equivalent stress distribution were analyzed in cutting area during EVT process. Furthermore, the microscopic cutting characteristics of elliptical vibration turning such as shear angle, chip morphology and temperature distribution of the tool rake face were further studied and compared with the ordinary turning process. The simulation results showed that the stress distribution was in a dynamic change process during elliptical vibration turning. Compared with conventional cutting, EVT technology can increase the shear angle, and the chip formed in the EVT process was thinner and had larger bending degree. Therefore, EVT technology has important application value in prolonging the service life of tools and improving the cutting performance of plastic materials.
