Embodiment Construction
[0015] A method for efficiently detecting TiAl-based alloy hot isostatic pressing products, comprising the steps of:
[0016] 1) Detection data, using the PowerScan-pro blue-ray precision 3D scanner to collect 3D point cloud data on the surface of TiAl alloy hot isostatic pressing parts, including blind cavity 1;
[0017] 2) data processing, the three-dimensional point cloud data is processed into a triangular patch format in the Geomagic quality software, and the splicing method adopts automatic splicing of marker points and automatic splicing of turntables;
[0018] 3) Comparative analysis of data
[0019] The detection software is used to conduct three-dimensional comparative analysis between the detection data and the theoretical model of the hot isostatic pressing of TiAl-based alloys, and output the detection report; the detection report can display the size deviation area in color, and use the data table to reflect the results of all dimensional elements.
