MATHEMATICAL MODELLING OF FORGING OF SINTERED PREFORM: COMPARATIVE STUDY OF OPEN AND CLOSED DIE
Abstract
This paper reports the investigation of the various aspects of forging of sintered square powder performs under open die and as well as closed die forming process. The deformation of sintered square disc for open and closed die forging has been discussed simultaneously and a Mathematical model is drafted considering the various decisive factors like friction, relative density, geometry and other forging parameters. An attempt has been tried for the determination of the die pressures developed of the disc during forging by using an upper bound approach.
