Abstract
Abstract
Bionic design of cutting tools to reduce working resistance and energy consumption has always been a concern of people. The curve of the rake face of beaver teeth is fitted and its general expression is obtained. The function is used in the configuration design of the bionic alignment of the front cutter face of cylindrical milling cutter, and the bionic curvilinear configuration rake face cylindrical milling cutter is designed. By constructing a three-dimensional milling simulation model of a cylindrical milling cutter, the cutting performance of a cylindrical milling cutter with a bionic collinear configuration and a cylindrical milling cutter with a flat front face was analyzed by comparing the milling simulation with a cylindrical milling cutter with a bionic collinear configuration composed of different combinations of front face collinear parameter values. The results show that the designed bionic collinear configuration front face cylindrical milling cutter exhibits certain force saving effect and is verified by right angle free cutting experiments, but its drag reduction performance is affected by the parameter values of the collinear. The optimized parameter values of the front face collinear of the tool with a certain side draft are obtained by genetic algorithm combined with finite element simulation analysis, and the optimal combination of collinear parameter values is obtained.
