Abstract: A sensitivity analysis based optimization method for forging die shape design using finite element method is presented. The sensitivity analysis and optimum design of preform die shape for disk forging process are performed. Optimum results show that a net-shape disk forging without side buldging is obtained using optimized preform die shape. The optimized preform die shape is smooth, simple and easy to manufacture and produce. The sensitivity analysis based die shape design method provides an effective and quantitative analysis method for net-shape forging die design of disk forging process.
