| 摘 要： | 采用逆向工程技术可显著提高模具设计效率。在重构零件模型的过程中,先对零件的曲面特性进行分析,然后划分若干曲面片,对每一个曲面片分别进行重构,再进行重新组合,产生过渡曲面,从而完成整个曲面的重构。利用重构好的曲面模型,进行零件的CAD实体模型的造型。最后利用该CAD实体模型,设计出注塑模具。结果表明,重构模型的精度可以满足零件的注塑模具的设计要求。采用该方法,可以实现模具的快速设计,缩短新产品的开发设计周期。 |

| Abstract: | Design and manufacturing efficiency is greatly improved by using reverse engineering.During the process of reconstructing model,characteristics of surface are firstly analyzed.The surface patches are then divided.Any piece of surface patches is reconstructed and a combined surface is built based on them.The transition surfaces are finally formed.The whole reconstructed surface is used to construct the CAD solid model.The injection mold is designed based on the CAD model.Results show that the reconstructed p... |
