| Abstract: | The industry computed Tomography inspection system could provide non destruction, accurate, effective and complete inspection methods for aero engine turbine blade production. The software of the inspection system organizes the blade CT slice images into a Three Dimensional Digital Sampling Model, on which performs inspecting and analyzing for blade dimension, profile deviation, wall thickness, casting defects etc, and at last generates the final inspection report. Some key techniques including blade Digital Sampling Model generating, profile deviation analyzing, and wall thickness inspecting were researched and validated by adopting a set of real turbine blade CT scanning data. |
