Past developments and future trends in the rotary or orbital forging process

  • Published:
Journal of Materials Shaping Technology

Abstract

Rotary forging is a relatively new manufacturing process with potential for cost-effective applications, especially in cold forging of intricate parts to net shape. In this paper orbital forging and axial die rolling processes are included as subsets of rotary forging while radial forging, also known as rotary forging, has been excluded; these decisions are primarily based on die kinematics. Because of its recent origins, the rotary forging process is first described. Then, a historical perspective is provided to trace its recent origins. The machines are classified based on die kinematics. Die kinematics influence the stick-slip or position discrepancy behavior of the different machine types and have deep implications on the die filling and accuracy capabilities of these machines. Rotary forging machines currently in operation in the U.S. and their applications are presented in greater detail. The discussion on future applications and potential research issues is primary based on the author’s own perception of future trends in this emerging field. The author is with.
