Abstract：

Precision rolling is an important processing method for aero-engine blades, and it is difficult to determine its process parameters, resulting in controlling the blade forming effect difficultly. Therefore, it was proposed to use finite element simulation software ABAQUS to simulate the rolling process, and by changing rolling reduction amount and friction factor, the coupling influence of the rolling reduction amount and the friction factor on the forming result for blade was studied. Furthermore, the process parameters were optimized, and the optimal parameter settings were obtained. The research results show that with the increasing of the friction factor, the overall blade width of the rolling model increases, and the rolling force is linear positive correlation with the friction factor. With the increasing of the reduction amount in port, the rolling force on the blade and the blade width increase, but when the reduction amount exceeds 0.06 mm, the rolling force and the blade width increase suddenly, and the blade deformation is concentrated in the local area of edge, which is not conducive to the precise control of the forming result.
