Radial forging is an open die forging process used for reducing the diameters of shafts, tubes, stepped shafts and axels, and for creating internal profiles in tubes. Due to very large forging load, the tool should withstand large stresses and wear. Therefore, the success of forging process depends upon recognition of the die failure factors and optimization of the tool working conditions that enhance tool life.In this study, the effect of process parameters on the tool life in cold radial forging process is investigated using nonlinear three dimensional finite element modeling. Wear and mechanical fatigue are considered as the main modes of tool failure and a parametric study on the effect of process parameters on tool life is presented.
