| 摘 要： | 异形拉深件的曲面复杂，用传统的测绘方法很难达到其精度要求。采用逆向工程技术理论对异形拉深件进行研究和分析，利用三维激光扫描仪对零件的几何特征进行数据扫描，并在Geo-magic软件中进行数据处理后导入UG软件实现模型重构，生成了零件三维数学模型。同时对所生成的异形拉深件模型运用Dynaform软件进行CAE模拟分析，模拟了发生形变的过程，在材料成型RE/CAD/CAE/CAM集成上做了一定的探索。

| Abstract: | Because of the complex surface of the drawing part, it is very difficult to meet the accuracy requests by traditional method. It analyzes the model of drawing part based on Reverse- Engineering technique. The geometrical figure of the drawing part is scanned by 3D laser scanning apparatus. Using geomagic, it dealts with the data, transfers into UG to reconfigure, and generates the components model. Meanwhile it analyzes the model of drawing part with Dynaform and simulates the process of deformation. It introduces certain ex- ploration of the integration on RE/CAD/CAE/CAM. |
