An engine manufacturer in Chengdu needs to perform 3D inspection on automobile engine cylinder blocks. The company uses a 3D scanner independently developed and manufactured by Holon, combined with 3D inspection engineering software, to obtain accurate 3D data of the engine cylinder blocks. The acquired overall data of the engine cylinder blocks is compared with the original CAD model for targeted data‑matching. By reviewing the overall actual scanned data of the engine cylinder blocks, the qualification of finished products can be analyzed.

1. Since the automobile engine cylinder block involves connections with multiple engine components, the accuracy required by the customer is extremely high.

2. This automobile engine cylinder block is characterized by a complex shape, greatly varied curved surfaces, and a large number of hole positions. Traditional measurement methods are very time‑consuming and fail to generate sufficiently accurate data.

      In response to the characteristics of automobile engine cylinder blocks, such as complex shaped surfaces, sharp curvature variations and numerous hole positions, Holon 3D technical engineers proposed a solution. The HL‑3DS+ 3D scanner is adopted to quickly acquire high‑precision 3D data of the automobile engine cylinder block. The engine point cloud data is converted into triangular mesh surface data by 3D inspection and design software, which is then imported into mainstream design software for post‑processing.
