This paper proposes a novel integrated modeling method based on cross-sectional imaging system which can implement the rapid and low-cost development for various engine cylinder bodies. The integrated modeling method which involves four steps: object pre-processing, cross-sectional image acquisition, CAD model reconstruction and redesign, is presented. Furthermore, an engine cylinder body was used to demonstrate the application of the integrated modeling method. The integrated modeling method proposed is characterized by simple process, short design cycle, and low-cost. It is particularly suitable for the 3D CAD modeling of an object with complex external and internal features. As a result, the method offers a good solution to implement the CAD modeling for a variety of complex objects with undercuts, hidden and internal features. |
