| Abstract: | The precision bending process of film-coated aluminum sheet to a long radius el- liptic sheet was discussed. The accurate solution and correction method of the bending springback amount was proposed, and the insufficiency of plastic deformation amount in the long radius bending was resolved by using reverse pre-bending technique. |
