Abstract
A finite element model of the matching of lengthened shrink-fit holder (LSFH) and cutting tool is established and the Rayleigh viscous damping model is used to calculate the reasonable structural damping of this model. A milling force model is developed to predict the transient milling force using back propagation neural network (BPNN). The dynamic characteristic of matching of LSFH and cutting tool is analyzed by means of the universal commercial software ANSYS10.0. The results of numerical simulation are obtained and verified against the practical measurements that show that they are consistent. This study is important to optimum design of LSFH, and to rationally choose the matching of LSFH and cutting tool, deformation analysis, error compensation and parameters optimization in high-speed milling.
