The cost of a forging die is around 20% of the total forging process cost. It is important, for total cost reduction, to improve the forging die life. Recently, the advances in the development of FEM have been marked, contributing to the development of simulation tools that are being effectively applied to the improvement of forging die life. First of all, we describe the approaches for die-life improvement approaches for the cases of fracture and wear by reliability analysis. Then, we introduce the application of those improvement techniques on the two cases.
