A Review of Radial Forging Technology Including Preform Design for Process Optimization

reportActive / Technical Report | Accession Number: ADA278770 | Open PDF

Abstract:

The Engineering Research Center for Net Shape Manufacturing located at Ohio State University, Columbus, Ohio was contracted by Benet Laboratories to investigate the rotary forging operation at Watervliet Arsenal. They were asked to make recommendations on how to optimize the shape and size of the starting material preform prior to forging which would reduce or eliminate variations in mechanical properties along the length of the resulting forging. Based on the data supplied by Benet Laboratories, the study resulted in recommendation of a two-step preform design. This was a preliminary recommendation and further testing was suggested to separate the effects of forging reduction from post-forging heat treatment.
