ABSTRACT:
A method and machine for forming a complete stamping die. A material erosion machining apparatus with a movable work table assembly and an extractor is used to draw a male punch from a female die blank. The female die blank has a rough-cut die opening. The part removed from blank is a rough-cut male die punch. The die opening side walls and the rough-cut punch side walls are generally parallel and tapered in the direction of the intended die draft. The die punch fits in the rough-cut die opening of the female die blank. The work table assembly and the ram platen are moved away from each other, simultaneously with material removing electrical energy between work table assembly and extractor. One work piece is attached to work table assembly and the other work piece is attached to the extractor and, as work table assembly and extractor are moved, the die punch blank is moved through the die opening of the female die blank with the tapered side walls in opposition to the direction of movement. As this passage is made, material is removed from the female die blank and the male die punch to generate the preselected die draft, die clearance, and exact registration. A complete die set is so formed by the method and machine.
