Recent development on three dimensional forging simulations and industrial applications

Abstract

The evolution of modern manufacturing technology demands ever-increasing international competitiveness of manufacturing processes and products, requiring less design and manufacturing costs. In order to achieve this goal, new materials and manufacturing processes or technologies to be applied can be sought with the help of a computer-aided-design system that is based on either artificial intelligence or numerical simulation analyses. Some important issues involved with this approach are discussed in this paper in terms of various aspects such as deformation analysis of the billet and elastic deformation analysis of the forming tools, prediction of microstructure evolution and tool life, and heat treatment after forming as a secondary process. In addition, a novel approach for friction and material property measurements by tip test will be introduced.
