METHOD FOR MANUFACTURING A SHEET MOLDED TO FORM A MULTI-DIMENSIONAL CURVED SURFACE

A method for manufacturing molded plates with multi-composite curved surface is provided to manufacture a forming plate having various cubic multi-composite curved surfaces. The operation program of an upper mold, a lower mold, a stretching forming unit, a marking robot, and a cutting robot is inputted (S1). The upper surface of the lower mold and the lower surface of the upper mold are formed into the shape of multi-composite curved surface (S2). After a metal plate is positioned on the upper surface of the lower mold, both ends thereof are clamped by multiple stretching forming units (S3). The metal plate is molded into the shape of the multi-composite curved surface (S4). The metal plate is marked by the marking robot (S5).
