PROBLEM TO BE SOLVED: To provide a technology capable of molding work along the shape of a metal mold, without deforming the work so as to be separated from the metal mold.SOLUTION: In a bending method, work W having two machined parts machined along shapes of a first recessed portion Lc1 and a second recessed portion Lc2 is placed on a lower mold L having the first recessed portion Lc1 and the second recessed portion Lc2, and bending machining is performed on the work W by using a roller 10 made from an elastic body. The roller 10 is deformed along the shapes of the first recessed portion Lc1 and the second recessed portion Lc2 so as to mold cross sections of a plurality of machined parts in the work W along the cross-sectional shapes of the first recessed portions Lc1 and the second recessed portion Lc2 and so as to keep the cross-sectional shape of the molded work W, by pressing the work W with the roller 10. While pressing the work W by the roller 10, the roller 10 is rolled to simultaneously and continuously mold the plurality of machined parts in the work W. |
