Aeronautical thin-walled parts are characterised by large dimensions, thin walls and high material removal rates, which is highly susceptible to machining deformation problems. Machining deformation seriously affects the quality of the parts machined, therefore, the machining deformation control of aviation thin-walled parts is of great importance. In this paper, a transmission reverse disc is used as the object of study, to optimise the machining position of the part by reconstructing the global residual stress distribution of the blank based on the monitored deformation forces during the machining process, at the same time, combined with the responsive fixture adaptive machining process, which enable effective control of the machining deformation of the part. The actual machining tests control the flatness and parallelism of the part to 0.11 mm and 0.04 mm respectively. The results show that the method can significantly control the machining  deformation of the part.
