Forging manufacturing technics processes are in the core of forging plastic deformation, which consist of a series of manufacturing procedure. The essence of forging forming is applying external force by means of tools or dies, workblank absorb mechanical energy, stress state will to be coming into being in internal, displacement and transformation flow of material point. For heat forging, workblank will also absorb heat energy because of being heated, temperature distribution relevant change will be happened in internal. Mainly driven by force-energy and heat energy, appearance shape and dimension and internal structure property of workblank will be changed.
