针对钣金零件的CATIA设计数模,利用其二次开发软件CAA,提取了CATIA特征树中的钣金零件综合信息.重点采用Drools规则引擎从复杂的特征树中提取待检测钣金零件的特征,并将特征信息存储到数据库中.
According to the CATIA designing model of sheet- metal parts, a secondary development of CAA- based CATIA is made to extract information from the CAT- IA feature tree. The importance of this thesis is how to ex tract features for inspection from the multitude detected in- formation with the method named Drools rule engine. And, then the inspection features information is stored into the da- tabase.
