In order to solve the springback problem after the sheet forming process, the springback compensation module was developed by the interactive mode of CAA V5 development method and the interactive development mode of CATIA, and the development of one step shaping compensation system for rubber bladder was conducted. Then, the plane interception compensation algorithm was put forward, and the surface to be compensated was discreted as several interception lines. Next, the intersection line of bending fillet line and bending surface in normal plane was compensated for springback, and the curve after springback compensation was formed as the post-compensation surface by the surface modeling function of CATIA. Furthermore, the reliability of the compensation module was proved by comparing the precision of the sickle shaped forming parts produced by the compensation die with the test die in the rubber bladder forming tests. Thus, the springback of forming surface could be compensated by springback compensation system, and the compensated forming surface could be used to design compensation die. The results show that based on the compensation algorithm, the original die can be compensated reasonably, and a design proposal for the design of compensating die can be provided.
