摘要：

The distribution of machining residual stress of nickel-based superalloys had a significant influence on the product quality. To achieve the control method of residual stress, the effects of processing parameters, tool parameters and mechanics-thermal coupling on the residual stress distribution of nickel-based superalloys were studied by means of simulation and experiments. It is found that the change of cutting depth will affect the radial and tangential residual stresses at the same time, and the change of feed rate per tooth mainly affects the residual stress in the feed direction. When the rotating speed increases, the temperature field becomes stronger, the materials are softened, the milling forces are decreased, and the thermal stress is gradually increased. The optimal proportioning scheme is obtained by the method of parameter combination proportioning. Taking the machining of engine blade parts as an example, the method based on parameter optimization may effectively control the residual stress of Nickel-based superalloys. © 2024 Chinese Mechanical Engineering Society.
