ABSTRACT:
An improved rotary cutting die and method of producing it are disclosed wherein a cylindrical die blank or support has a weld bead applied on its peripheral surface in a configuration corresponding to the design of the product to be formed. The weld bead is then ground to provide a working surface spaced a predetermined distance radially above the die blank surface whereupon the weld bead is electrical discharge machined to form the required cutting edges coincident with said working surface.
