This project focuses on a large helical cutter roller, which has an overall helical surface and a multi-axis complex structure. Since the original design drawings are missing and the cutter roller has experienced edge wear and helical angle deviations over long-term use, the client needs to use 3D scanning and reverse modeling to restore an accurate digital model, while also checking the geometric tolerances of worn areas (like cylindricity and helical line deviations) to provide a basis for maintenance or modification.

The spiral cutter roller is long and heavy, making it impossible to move. Its continuously changing spatial spiral and blade surface are hard to fully and accurately measure with traditional manual methods or regular contact techniques, making it tough to meet the data requirements for reverse reconstruction.

Using the Huarang 3D industrial-grade scanner, the spiral cutter roller is scanned in a full, non-contact way. This scanner has an accuracy of up to 0.02mm and can densely capture complete point cloud data of the roller surface, effectively solving the problem of missing data on complex curved surfaces.

Import the acquired high-density point cloud data into professional reverse engineering and inspection software (like Geomagic Studio). First, build an accurate 3D digital model of the cutting roller. Then, use the software’s 3D comparison function to precisely align the reconstructed model with the original CAD design model and perform deviation analysis, automatically generating a visual color-coded deviation map. Through this process, Hualang 3D successfully obtained a high-precision digital model of the helical cutting roller and accurately quantified the deviation between the actual manufacturing and the design model, providing scientific and reliable data support for clients to evaluate manufacturing processes, improve designs, and conduct subsequent finite element analysis.
