Simulation and virtual reality-a key factor in future development of metal forming processes

In recent years the metal forming industry utilizes practical and proven CAD, CAM and CAE techniques. The development of numerical simulation methods has created new feasibilities with great industrial aspects as regards optimisation of metal forming processes. By applying such methods of analysis it is now possible to visualize the internal material transformation and predict the interactions between material properties and forming process, material flow, form filling and defect formation, optimise process variables as well as predict die stresses for preventing premature die failure. This paper summarises the state of simulation technology and reviews various applications in most important forming processes, forging, stamping, deep drawing and extrusion. As increasingly demands to manufacturing industry of faster, better and cheaper production has intensified the research and development of this technique a brief discussion is given concerning applications and future trends.
