Analysis of Innovative Incremental Cold Forming Process for the Manufacturing of Aerospace Rotating Parts [PDF]
Volume 1: Processes, 2017 Cold rotary forging is an innovative incremental metal forming process whose main characteristic is that the workpiece is only partially in contact with a conical tool, reducing therefore the required forging loads. However, in spite of many benefits of such a process, wide industrial implementation of rotary forging is not possible without proper ...
