Process and tool design for precision forging of geared components

Precision forging is an innovative manufacturing process for the flash less, near-net-shape production of high performance components. Outstanding material characteristics as well as a reduced process chain and a high material efficiency are the essential advantages of precision forging. Only defined functional surfaces need a finishing after the forging and integrated annealing process. The increased mechanical and dynamical component strength forward the trend of light weight construction. The requirements regarding accuracy in dimension demand high standards of process and tool design. An important part of the current research work is beyond the basic process design and tool construction the correction of geometry and material influences on the shrinking of the hot forged parts.
