The impact of the press displacement of the upper roller on the forming process of BBBR was studied and it was concluded that the lengthways curvature of the spherical part is very sensitive to the press displacement under fixed distance between two lower rollers. The effeet of friction condition on the forming process of BBBR was discussed. The springback behavior of the process was analyzed preliminarily. The simulated results were validated by experiments.
