Abstract

Abstract: Increasing thrust-to-weight ratio is the goal pursued by aero-engines. Aero-engine blades are the core components of aero-engines. In order to reduce the weight and improve the thrust-to-weight ratio, the cavity structure is gradually applied to aero-engine blades. The constraints of the outer contour and the inner wall thickness of the cavity structure blade make its trajectory planning difficult, which seriously affects its surface roughness and profile accuracy. In this study, proposes a titanium alloy blade surface machining method based on belt grinding, which is constrained by two dimensions of contour and wall thickness, and the process parameters of titanium alloy material specimens are studied. The obtained parameters are applied to the blade grinding process, the grinding trajectory is planned, and finally parameters of the blade are tested. The processing and testing results verify the effectiveness of the method in this paper.
