An internationally renowned research institute needs to conduct a full range of inspections on the processed nuclear devices and compare the digital and analog diagrams of the products. In order to improve the processing technology of the nuclear device and improve the quality.

Practical problems

1. The nuclear device accessories are large in shape, complex in shape, and have many holes, which require high accuracy of the acquired three-dimensional data.
2. The traditional measurement method has insufficient data collection density (insufficient amount of data) and cannot measure the curved surface and arc on the nuclear device, cannot perform normal inspection, and cannot reverse mapping in the later stage. The workload is large, the efficiency is low and the accuracy is not high, and it cannot meet the customer's requirements.

The three-dimensional scanner performs three-dimensional scanning of the nuclear device, obtains high-precision three-dimensional data, and finally generates a detailed inspection report. Any position deviation can also be displayed numerically, which can completely replace traditional inspection methods. 　
1. Preliminary preparations
       Spray developer: improve the contrast of the background color on the surface of the sample and obtain better scan data.
      Marking points: Positioning and splicing the acquired data in the scanning software.

2. Three-dimensional scanning
      After learning about the company's specific situation, Hualang 3D engineers used the combination of Hualang 3D scanner HL-3DW and 3D scanner HL-3DX to scan it. HL-3DW has a large format scanning function, which is very suitable for scanning large objects. , The machine is very stable, the entire scanning process is only one hour, with an accuracy of 0.05mm, and 3DX can accurately scan those holes and improve the detection data of the nuclear device.

3. Three-dimensional inspection:
      Import the acquired 3D data of the nuclear device into the inspection software Geomagic Qualify, which can quickly detect the difference between the nuclear device (CAD) model and the manufactured parts of the product. Geomagic Qualify can show the difference between the two with intuitive and easy-to-understand graphical comparison results. .
