A method and machine for forming a complete die such as a stamping die. There is provided a die forming machine having a material erosion machining apparatus with a movable work bed and an extractor, each having means for mounting a work piece. One of the work pieces is a female die blank with a rough-cut die opening. The other 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 blank fits in the rough-cut die opening of the female die blank. The work bed and the extractor are movable away from each other, simultaneously with material removing energy discharge between the bed and the extractor. One work piece is attached to the bed and the other is attached to the extractor and as the bed and the extractor are moved away, 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 and die clearance. A complete die set is so formed by the method and machine. |
