Abstract

Precision forging is an innovative manufacturing process for the flashless and 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 final hard-finishing of specific functional surfaces with minimum cutting volumes is necessary. The increased demands on the dimensional and geometric accuracy of precision forgings result in increased requirements for the applied forging tools, the forming machines as well as for the specific design and control of the process. Precise tool and process design requires a detailed knowledge about material-specific heat balance resulting in a process and tool-related heat transfer. Hence, the influences of geometry and material on the shrinking of the hot-forged parts are an important part of the current research work.
