Numerical Analysis of Lateral Forces in a Die for Turbine Blade Forging

There are various processes for production of turbine blades. Hot forging has been the most common, especially for automotive, marine and industrial turbochargers or aero-engines turbines. Advanced computer modelling has become a powerful tool for process planning and tool design in order to get near-net shape blades in hot forging. This paper presents the effect of die cavity positioning on metal flow and distribution of lateral forces in the die during aero-engine turbine blade hot forging. An influence of torsional moment on dies offsetting introduced by these lateral forces has also been pointed out.
