Closed Die Forging of Turbine Blades

This paper comprises a theoretical and experimental investigation dealing with the simulation of closed die forging of turbine blades. The theoretical part was achieved numerically via the well known finite element package (ANSYS). For simulation purposes, the material used for blade manufacture was high purity lead (99.99%), which was pressed between two dies with the required shape of the turbine blade. An optimum flash-less die shape was obtained with a parting line angle of 16°.
