For a certain grade of the aviation engine stator blade surface machining, complex shapes may cause a difficult situation of blade deformation control. Through the high-order curve fitting method, the three-dimensional model of blank moleds and blades are established, and ANSYS/LS-DYNA software is used to simulate the blade rolling process. According to the results of the simulation of the blade cross section, nodes are select to study the blade surface's normal and lateral deformations caused by the rolling friction coefficient, the rolling speed, the rolling amount of pressure. Different parameters influencing the deformation of blade surface and the laws of the rolling process are obtained. The results show that the maximum deformation area of the blade is in the dorsal arc position of the steep slope, where the blade surface curvature is large. The error is also generated by the maximum strain. The deformation amount of the blade increases with the rolling friction coefficient decreasing, reduces with the rolling speed increasing, and increases with the rolling amount of pressure increasing. The results can provide a theoretical reference for a certain grade aircraft engine stator blade processing design.
