Review:State-of-the-Art of Stamping-Forging Process with Sheet Metal Blank

The aim of this paper is to review the state-of-the-art SFPs and their applications, and to provide a guide for researchers and engineers working in this field. Various SFPs are classified according to the combination ways of stamping and forging operations.The process principle of each combination is reviewed, with its applications discussed. The state-of-the-art of SFPs suggests that future work in this field should focus on the development of high-strength die materials, better lubrication control methods, forming machines with intelligent control capacity and special functions, and some new SFPs for high strength or ultra-high strength materials.
