摘要: This paper aims to present a predicted force model of vibration-assisted broaching (VAB). Based on the geometric features and kinetic characteristics of broach, the model focuses on three important points:(i) the cutting force of single tooth,(ii) the number of teeth in contact with the workpiece, and (iii) the influence of simple harmonic motion (SHM). Firstly, according to the empirical approach (EA) and the shear angle (SA) theory, two kinds of single-tooth model of broaching are built. Secondly, considering the length of cutting edge …
