In this paper, the three-dimensional rigid-plastic finite element simulation and experimental research on the precision forging process of hollow spur gear is carried out. Through the finite element numerical simulation and experimental study, the metal flow regularity and deformation mechanics characteristics of the spur gear were obtained, and the deformation mechanism of the spur gear was revealed. The numerical results agree well with the experimental results
