Abstract Rubber fluid forming technology is one of the main methods for aviation sheet metal forming, while
the springback is the main defect that affects the manufacturing precision of sheet metal products. In order to improve the
manufacturing precision of the aviation manufacturing level, domestic researchers have carried out a lot of researches and
practices, but the effect of engineering application of various methods is not ideal. In this paper, springback prediction
method based on the numerical simulation and rapid springback compensation method based on geometric features of parts
are reviewed, the advantages and disadvantages of the two methods are compared and analysed. Combining with the aviation
enterprise engineering application and practical demand, the solution of combining the two methods is proposed.
