Effects of cutting and vibration parameters on transient cutting force in elliptical vibration cutting

Abstract

As a novel vibration-assisted machining method, elliptical vibration cutting (EVC) technique has been found to be a better technique, compared to conventional cutting and conventional vibration cutting techniques. Due to the transient thickness of cut and continuous variation of tool velocity direction, its fundamental cutting mechanics is different from other cutting techniques. In the field of metal cutting, cutting force is usually considered as the most important indicator of machining state and quality. Analysis of the cutting force plays a vital role in determining and predicting various machining performances. In this study, a series of low-frequency orthogonal EVC tests were conducted to study the effects of three essential parameters on the transient cutting force values. It is found that the transient cutting force increases with the increment of speed ratio, the increment of tangential amplitude, and the decrement of thrust amplitude. © 2012 Springer-Verlag.
