Abstract

Precision forging is an innovative manufacturing process for the flashless, 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. Subsequent to the forming process only a final hard-finishing of specific functional surfaces with minimum cutting volumes is necessary. The high accuracy of precision forging demands a specific process and tool design. In this regard a detailed knowledge about fundamental material properties and the forming procedures predefined by the applied machine kinematic is essential.
