The processing quality of thin-walled parts directly affects the service performance of high-end equipment in the defense industry such as aviation and weapons. However, as a typical weak stiff-ness part, the serious machining deformation caused by the introduction of residual stress in the entire manufacturing process is difficult to meet the requirements of manufacturing accuracy and quality. Based on the analysis of the residual stress-induced deformation mechanism, the existing residual stress deformation prediction methods are classified and summarized in this paper, and the characteristics of the related methods are expounded. At the same time, according to the main sources of deformation, the existing residual stress deformation control methods are summarized from two aspects: initial residual stress and cutting residual stress. Finally, the future research on residual stress deformation and control technology of complex thin-walled parts is prospected. %K 薄壁零件,残余应力,变形预测,变形控制;Thin-Walled Parts %K Residual Stress %K Deformation Prediction %K Deformation Control %U http://www.hanspub.org/journal/PaperInformation.aspx?PaperID=59305
