摘要：
The scientific inspection of blade profile machining quality is one of the key technologies to ensure the high aerodynamic performance of aero-engine turbine blades. In the view of fact that the current visualization inspection results of blade profile surface are low and it is difficult to analyze the machining error of blade profile accurately by the conventional 3D model comparison methods. Based on the definition of blade profile surface, an adaptive triangular mesh model with node layers feature and a visual analysis method of main machining error of blade surface was proposed, and an experimental study was carried out on the profile surface of a certain type of blade. The results show that this method and its corresponding software system can visually and accurately visualize the blade profile error, the distortion error, the swept deformation error, the bending deformation error and the cross-section linear contour error. It reduces nearly 30% of the text information in the result of the blade feature detection, and it can effectively assist the quality inspection personnel to carry out the analysis and evaluation work of machining quality of blade profile. © 2019, Editorial Department of Journal of Propulsion Technology.
