摘要
逆向工程作为一种先进、快捷和实用的现代设计方法得到了学术界和企业界的认同,并得到了广泛应用。文中以汽车轮毂帽为逆向研究对象,采用三坐标测量机采集实物原型表面的一组特征数据点,并运用Unigraphics软件对特征数据点进行NURBS曲线和曲面拟合,生成三维原型数字化模型。
Reverse Engineering has got the approval of the academia and business fields as a kind of advanced . swift and practical modern design method, and used widely. In this paper regards hubcap of the automobile as the research object ,adopt three-dimension coordinate measure machines to gather the eharacteristic data of the prototype surface ,use Unigraphics to fit these data in NURBS curve and surface,produce the three-dimensional protoype numerical model.
