Pro／Engineer在逆向工程曲面造型上的应用

介绍了在逆向工程曲面建模过程中,使用美国PTC公司的Pro/Engineer三维造型软件,处理由三坐标测量机所测得的大量点数据,建立符合工程要求的曲面的方法。着重阐述了由大量数据点进行不规则曲线、曲面反求的完整技术。探讨了在Pro/Engineer环境下,直接从三坐标测量机产生的数据文档生成合乎工程要求的三维曲线,进而生成三维曲面的方法。通过对实验测量的涡轮表面数据的处理,在Pro/Engineer中建立了符合工程要求的涡轮曲面,从而证实了本方法的确实可行性。

Applications of Pro/Engineer in Reverse Engineering Surface Modeling

Introduced in the process of reverse engineering in surface modeling by Pro/Engineer software produced by PTC corp.,and the way to build satisfactory surface models composed of large 3D-points datum surveyed by CMM (Coordinate Measuring Machine).The emphasis is to build anomalistic curves and surfaces from numbers of datum.This paper especially probes into how to produce engineering 3D-curve directly from CMM datum file under Pro/Engineer environment.Through dealing with the datum of turbo gathered by CMM and building turbo surface,the method is proved to be feasible.
