New concepts in die design - physical and computer modeling applications

The application of Computer Aided Engineering ana physical modeling techniq ues in forging R & D continues to increase. In using tools such as Finite E lement Modeling and experiments with model materials, the forging tool desi gner san decrease costs by improving achievable tolerances, increasing tool life, predicting and preventing flow defects, and predicting part properti es. At the Engineering Research Center for Net Shape Manufacturing, Design Environment for Forming (DEFORM) and DEFORM 3D, and a multiple action press for physical modeling are tools available for forging research and for edu cational purposes. This paper summarizes the results of industrially relevant "work-in-progres s" research with numerical and physical modeling systems. Current projects include: a tool design for the forging of a cross groove inner race fur a c onstant velocity Joint, and the design of a tooling to forge a connecting r od without flash.
