In the process, the plate is deformed incrementally as the deformation proceeds simultaneously in longitudinal and transverse directions in a stepwise manner. For the industrial application of this process, the forming information (such as bending radii) must be determined considering the springback phenomenon that is inevitable in the sheet metal forming process. In the present study, the process design program calculating forming information for the manufacture of doubly-curved plates is proposed. The calculation program using the iterative scheme has been implemented with Visual C++ language. To check the validity of the developed program, experiments were carried out. From the experimental results, it has been demonstrated that the cold roll forming system has the general applicability for the manufacture of ship hull plates.
