The finite element model simulation and mathematical model calculation of the deformation in the machining process of split straight bevel gear are carried out. After comparing the results of the two models, the rationality and scientificity of the model are preliminarily verified. In order to verify the accuracy of the theoretical calculation of straight bevel gear blank and the straight bevel gear blank, and further verify the accuracy of the theoretical calculation of straight bevel gear blank and the spur gear blank.

1. In order to further verify the correctness of finite element simulation and theoretical calculation, the machining experiment of split straight bevel gear is planned in detail. The NC machining code generation and Simulation of straight bevel gear blank are realized by using the cam module of UG, and then the machine tool simulation is carried out in VERICUT software to ensure the smooth progress of the experiment.
2. After the straight bevel gear is split into blanks, the position tolerance and deformation of the machined straight bevel gear blank surface are measured with a three coordinate measuring instrument. The experimental results show that the experimental results are similar to the simulation processing, which verifies the correctness of the theoretical model and finite element simulation, and lays a foundation for the next research on the straight bevel gear split into blanks.
