Abstract

The performance requirements of mechanical equipment for gears are also constantly increasing. Hobbing is a gear machining method that meets the needs of the product. The hobbing process is an extremely complex multi-edge interrupted cutting process. It is important to predict and analyze the cutting force of the tool to understand the effect of tool wear on the hobbing parameters. Therefore, this paper studies the cutting force prediction problem of hobbing. Firstly, using the mathematical model of the hobbing motion relationship, the mathematical models of the two-dimensional hobbing state and the three-dimensional hobbing state are established respectively, and the cutting area of the hob teeth is analyzed. Then, based on the finite element simulation, the cutting force of the hobbing teeth is calculated and compared with the analytical results. The experimental results verify the effectiveness of finite element simulation on the prediction of hobbing cutting force. The research results can provide a theoretical basis for the selection of cutting parameters.
