Abstract: A method and die set for manufacturing a metal component with a three-dimensional edge from a blank as a raw material. The blank is cut from a metal sheet and has a curve-shaped curved edge portion with two ends. The method includes providing a bend formation line and forming the three-dimensional shape using a first die and a second die.
