CAPP 中工序图的自动生成

工序图自动绘制是ＣＡＰＰ系统中的一个重要组成部分。在ＣＡＰＰ系统中实现工序图自动绘制有着十分重要的意义。本文所叙述的工序图的自动绘制模块是通过将零件分离成各种特征，在参数化绘图的基础上实现的。

The automatiic generation of parts proecssing sketch is an important part of CAPP system.So if it is realized in CAPP system,it will make great influence on our work.In this research,the program of automatic generation of parts processing sketch,which is based on parametric drawing,is completed by means of defining features of parts.
