Research on development methods and application of CAD system of prac tical sheet metal expansion

在分析钣金展开计算和绘图方法的基础上 ,详细地讨论了实用钣金展开CAD的系统结构和开发方法。最后结合钣金展开应用实例 ,系统地说明利用几何数学计算法结合计算机辅助设计和AutoCAD系统的绘图环境 ,如何进行钣金件展开计算 ,自动生成钣金展开图和相应的展开计算数据文件。目前 。

On the basis of analyzing expansion calculation of sheet metal and met hods of drawing, the system and developed methods are detailedly discussed on CA D of practical sheet metal expansion. And it is systematically explained how to do expansion calculation of sheet metal parts, automatically draw its unfold dra wing and make relative data files of expansion calculation by using geometry, ma thematics, computer aided design and AutoCAD system. At present, the method has been successfully used to develop CAD system of sheet metal expansion.
