Abstract

In the paper numerical analysis of closed-die forging process of turbine disc to fix blades was presented. Forging technologies which take into account conventional and isothermal boundary conditions were analysed. Forging processes were lead as one stage or as two stages - with initial upsetting. In the analysis additional influence of lubrication conditions on the process parameters was taken into account.
