Medium and large mould inspection  Case background The inspection of large and medium-sized dies has always been a problem for processing units. It is difficult to load and unload equipment by using traditional three-coordinate system. The inspection process is complex and the inspection efficiency is low. Using 3D scanning equipment alone and relying on the traditional method of splicing public signs, not only the amount of data is large, but also the cumulative splicing error is large, so it is not fully competent for the detection work. Through the cooperation of XTDP and XTOM,not only the global accuracy can be controlled, the accumulated error can be avoided, but also the splicing efficiency can be improved, the overall inspection efficiency can be improved, and the inspection of large and medium-sized dies can be completed. Use equipment XTOM-MATRIX 5M 3D optical surface scanning system Inspection process Surface treatment, spraying of imaging agent and sticking of marking points are carried out. Firstly, the XTDP 3D optical photogrammetry system is used to calculate the global points by taking pictures from different angles of the mould. This method can not only control the global accuracy of the measurement process, but also freely splice the scanning data in the subsequent scanning process. It does not need the traditional way of splicing by common parts. It not only improves the overall accuracy, but also improves the overall efficiency. After completing the above work, XTOM is used to scan the data, and the data splicing is automatically completed, so that the 3D data can be obtained accurately and efficiently. By comparing the scanned data with the design model in Geomagic Control X software and setting the corresponding tolerances, the corresponding test results can be obtained and the final test report can be output. |
