摘要
图形之间的对比成为CAPP系统开发的瓶颈,详细阐述了基于STEP的属性图形表示法,在此基础上,将设计的零件图形与数据库中已有图形进行对比,并提供了算法.
The matching between two graphs is the bottle neck of development of CAPP. In the paper, the representation of attributed graphs based on STEP is given out. Based on the representation, the graph of newly designed part can match the graph in the database. Finally, the algorithm is provided.
