Pipe plants use radial forging to reduce the diameter of shafts, tubes, and axles. A three-dimensional finite-element method employing the software DEFORM-3D is used to optimize the radial forging operation. Three different tool configurations are examined for obtaining smooth and folded reduced semifinished products, and suggestions are made for an efficient shape for the tubular semifinished product prior to drawing, the design of the dies, and the configuration of the tool.
