箱体CAPP中零件信息描述及其算法的研究

Study on the Description and Calculation Method of Part Box Information in CAPP

针对箱体类零件特征以及CAPP系统对零件信息的要求,采用二叉树遍历的箱体信息描述方法,并用前序遍历算法在AutoCAD环境下获得了箱体类零件的几何与拓扑信息,并可直接传给CAPP系统,便于实现CAD与CAPP的有效集成。

This paper studies the description method of part box information considering its character and the need of CAPP. The geometrical and topological information of part box is obtained in the environment of AutoCAD by the method of preorder traversing binary tree, and the information can be transfer (directly) to CAPP, so it is convenient to combine CAD with CAPP by this description and calculation method.
