Abstract: With the development of machine tool machining performance and tool cutting performance, thin-walled parts can be machined with high efficiency and precision, leading to their wide use in the aerospace field. The complex structure and low rigidity of thin-walled parts make them easy to deform in the milling process. Therefore, accurate prediction and control of thin-walled parts deformation is an urgent technical problem to be solved in the field of machining. Through classification of thin-walled parts and analysis of the processing technologies, the factors causing the deformation of thin-walled parts are summarized, and the most basic calculation model of milling force is briefly introduced. Research on deformation prediction and control methods of thin-walled parts at home and abroad is reviewed. It is found that deformation of thin-walled parts is predicted by using the elastic-plastic theory and the numerical simulation method, and deformation of thin-walled parts is controlled by process optimization, auxiliary support technology, high-speed cutting technology and numerical control compensation technology. Based on update and iteration of data-driven digital twins, deformation prediction and control of the actual processing of thin-walled parts are realized. The theoretical framework of deformation prediction and control of thin-walled parts processing is built based on digital twins. Development and application prospects of digital twinning deformation prediction and control in thin-walled parts processing are also discussed.
