CAPP系统中输入子系统的图形技术

The Panern Techniques in the Input Subsystem at CAPP

本文论述了ＣＡＰＰ系统中输入子系统的图形处理技术。系统采用型面要素分解法输入，并对零件图形实时显示，较好地解决了零件信息描述，在图形处理及菜单技术有一定特色，本文还论述了图形实时显示的原理和方法。

In the paper,the authors explain the pattern techniques in the input sub-system at CAPP,using the form factor,decomposition input method and the synchronistical display of parts pat- tern,which greatly solves the problem of information description of cylindrical parts and really has unique feature in pattern treatment and menu-driven techniques.The principle and method of pattern synchronistical display are discussed as well in this paper.
