Forming laws in precision forging process of blade with tenon by 3D coupled thermo-mechanical FEM simulation

Blade is one of the most important mechanical components in an aero-engine. In this paper, considered different deforming velocity, friction factor and forging temperature of billet on precision forging process, the forging process of blade with a tenon is simulated and analyzed using a 3D-CTM (3-Dimensional Coupled Thermo-Mechanical Forming Simulation) developed in order to obtain forming laws in the precision forging process of blade. This study is important to optimization of precision forging technology and the development of precision forging.
