3D scanning casting quality monitoring and 3D inspection solutions

After the large-scale casting is formed, errors will occur due to the deformation of the sand mold during the casting process and the shrinkage deformation after the casting is formed. If the processing size of the castings due to deformation or shrinkage is insufficient, the entire casting will be scrapped and cause huge losses to the enterprise. Preliminary rapid 3D inspection of the key dimensions of the casting can determine whether the subsequent processing margin is qualified, can improve the production cycle of the mold, and create considerable economic benefits for the enterprise.

The problem we are facing

1. Due to the large size of large castings, it is difficult to use the traditional contact coordinate measuring machine, and the efficiency of the traditional coordinate measuring machine is low.

2. The casting itself is irregular. Different surfaces have the same radian but the size and direction of the radian are different. If you use traditional measuring tools, it is not just a problem of slow work efficiency. For example, there is no way to obtain the prepared 3D data for the arc, the inclined plane, and the curved part!

Scan the scene

1. According to the characteristics of the length and radian multi-faceted structure of the casting, the technical engineer of Jingyixun proposed a full-parameter 3D inspection solution for the casting. The model PTS-S photographic 3D scanner is used to quickly obtain the 3D data of the casting. The scanning of different sides can move the 3D scanning. The instrument scans, not only the accuracy of the 3D data is high, but also the scanning speed is fast, and the 3D data of the complete casting is successfully obtained.

2. Full-parameter three-dimensional testing of castings, using professional three-dimensional testing software to quickly complete the automatic 3D comparison and error analysis between the drawings provided by the customer and the castings

A. Batch processing of inspection reports for scanned 3D data; full target measurement with a size of 0.03mm

B. It can detect parting line, characteristic line, thickness, shape edge, contour deviation and boundary deviation, section, radian, etc.

C. It can be compared with the specified points on CAD in detail, and can analyze the surface continuity and curvature flow to ensure the quality of the casting

Summary

The 3D scanner provides a high-efficiency 3D inspection program for casting inspection. The 3D scanner can quickly obtain complete 3D data of the casting. The 3D data obtained by 3D scanning can be compared and analyzed with the original 3D data, and the 3D inspection report can be intuitively displayed. Look at the full-scale data of the casting. The three-dimensional scanner is directly used in the quality monitoring and detection of rough castings, and the design reference of rough castings (calculate the reserved amount)
