A client requested the reverse engineering of an impeller. No drawings or tooling existed for this product and the client needed to manufacture this impeller locally.
The metal casting was scanned. The part was scanned using the co-ordinate measurement machine. 3D co-ordinate points were transferred and converted into splines. Data smoothing and manipulation were performed by the front end CAD system and exported to the CAD system. A surface model was produced utilizing advances surface modeling techniques.
3D CAD surface model was exported and transferred. 2D manufacturing drawings were made of the impeller according to SABS 0111 specification.
