Numerical investigation of the performance of elliptical vibration cutting in machining of AISI 1045 steel

This paper investigates the performance of elliptical vibration cutting (EVC) in machining of AISI 1045 steel using AdvantEdge finite element simulation. The effectiveness of two key parameters frequency and amplitude is discussed. The purpose is to explore the effect of EVC on machining performance and to compare it with conventional cutting process, to prove that the EVC technique could generate better surface finishing. To be specific, the following aspects are compared: cutting force, shear stress, normal stress, Mise stress contour, and temperature variation; the residual stress is also examined. It is found that EVC has lower cutting force, stress, and temperature, and the residual stress acts out small change compared with conventional cutting. The frequency and amplitude all have influence in their own way on machining process.
