Abstract:

In order to further optimize the machining accuracy in the process of mechanical manufacturing, computer simulation, analysis and simulation based on finite element have attracted extensive attention and obtained rich research results since they were put forward. The rapid popularization and popularization of finite element technology effectively improves the machining accuracy of mechanical manufacturing, and the experimental research of mechanical manufacturing process promotes the optimization and improvement of finite element technology. This study combs the research process of residual stress prediction and finite element analysis, and summarizes the strategies and methods to improve machining accuracy. At the same time, the shortcomings and deficiencies of the current finite element analysis technology are described in detail, and the problems and directions of the follow-up research of finite element technology in the field of machining are put forward.

Key words: machining, finite element method, machining accuracy, turning, grinding, orthogonal cutting, grinding simulation, grinding wheel modeling
