Press-Forging Thin Sections: Effect of Friction, Area, and Thickness on Pressures Required

Abstract

The application of press forging to parts with thin sections is desirable in many instances. It is generally recognized that in forging such parts, the pressure required may be very high. That this high pressure required is due to friction has been reported; however, very little specific information on the effects of friction, area, and thickness is available. The results of this analysis resemble, in some respects, those presented in an analysis of forces required in rolling by Nadai.
