Short summary
The presence of initial residual stress is a major contributor to machining distortion. To control machining distortion, the transition structure before the finishing stage is optimized in this paper. The first step is to create a machining distortion analysis model for long beam parts based on initial residual stress. The transition structure's topology optimization model is then established. Finally, a verification case is used. The proposed model is verified by simulation and experiments.
