Abstract
A method for incrementally forming includes: preparing a tool T disposed on one side of a metal plate W, a fixing jig 1 to hold a periphery of the metal plate W, and a template P1 including a molded edge E that follows at least a part of a contour of a part to be processed F; arranging the template P1 on the other side of the metal plate W; holding the periphery of the metal plate W together with the template P1 by the fixing jig 1 to fix the metal plate W and the template P1; and moving the tool T while pressing the tool T against the metal plate W, to incrementally form the part to be processed F having a three-dimensional shape of the metal plate W.The method enables to form the part to be processed F in high precision with no use of a molding die and thus, is effective in bringing about reducing cost of equipment and manufacturing.
