| Abstract: | Large deformation appears after turning of ultra-thin parts. To realize the prediction and analysis of the deformation, a finite element simulation system was established to simulate the finishing process. The accuracy of the finite element system was verified by the machining experiment. Deformation of ultra-thin parts after unloading was explained based on the system, which could guide the improvement of processing and reduce deformation. |
