Forging quality and technical economic benefit of plastic working industries strongly depend on preform sequence and preform design.Because of the complexity of problem,the preform sequence and preform are usually determined through trial and error method based on practical experience and intuition.Obviously,the above situation could not meet the needs of development of high tech dominated by information technique.In present paper,a new preform design method based on FEM numerical simulation and optimization was presented,and several know how that must be solved during the implementation of the new method were investigated.The preform for FGH95 turbine disk forging was designed by using the preform optimization prototype system developed by the authors,the obtained results were satisfied.
