Abstract: A method of machining a screw is provided that is capable of preventing formation of a protruding section at a thread tip section. A thread is formed by cutting on a cylindrical body, and a surface of the thread is plastically deformed by rolling. Because of the cutting, a width between-side surfaces of a thread tip section is in a narrowed state as compared to a normal width. This width is narrowed toward a tip of the thread while a thread body section has a width expanded as compared to a normal width. Consequently, the side surfaces are formed to bulge by an excess thickness portion as compared to normal side surfaces. The rolling plastically deforms both side surfaces to cause the excess thickness portion to plastically flow toward the side surfaces.

Abstract: A deep drawing die is provided having a top die with a hold-down clamp, a bottom die with a die plate, and at least one device arranged in a flange region, by which the distance between the hold-down clamp and the die plate can be modified in portions or partially. A method for deep drawing a workpiece with a deep drawing die includes inserting a workpiece between top and bottom dies, deep drawing by closing the dies, and controlling at least one actuator to generate a holding force during deep drawing. By selectively increasing forces in the flange feed at selected locations between hold-down clamp and die plate, it is possible to control the flow of material into the die plate and relieve load on regions having high deforming work, so that tears or cracks at these points in the finished component can be prevented.
