| 摘 要： | 采用构造体素法(CSG)/边界表示法(Breps)混合式表示模式来完成冲裁零件的几何造型，具有实时显示、高效输入的优点。结合双向循环链表和二叉树这2种数据结构有效表征了包含冲栽件图形几何信息与拓扑信息的数字模型。从而为面向工程的模具CAD／CAPP／CAM集成提供了理论上和技术上的可靠基础。

| Abstract: | The geometric modeling of blanked parts can be performed by adopting the combination of constructive solid geometry(CSG) and boundary representation (BReps), which has shown advantages of real-time display and effi- cient input abilities. The numerical model reflecting the geometry and toplogy features of a blanked part is well rep- resented by means of the data structure combining the doubly linked list with the bifurcated tree. |
