Influence of die variables on cavity press forging loads.

Slug, die and process parameters largely determine the load requirements when forging any given part. An earlier report (Balogun 1974) has indicated the effects of flash dimensions on deformation forces during cavity press forging of round mild steel slugs. The current paper discusses the influences of three main die variables--die friction, extrusion ratio and flash land shape on press forging loads. The effects of die corner radii, draft angles and die complexity are also briefly mentioned to give a balanced outlook. [ABSTRACT FROM AUTHOR]
