摘　　要：超薄零件车削加工后存在较大的变形,严重制约了该类关键器件的广泛应用。为实现超薄零件加工变形的预测与分析,基于力学分析,建立了加工仿真系统并进行超薄零件精加工过程模拟研究。实际加工验证了所建立模型的准确性,同时基于该系统对超薄零件加工后变形进行分析,其结果对改进加工工艺和减小工件变形具有指导意义。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.
