【摘要】 研究了从中性文件STEPAP203文件中得到加工几何特征的方法。首先分析了STEPAP203文件的组织结构,然后从中提取有关面和面之间的连接信息,用属性邻接图表示出来。讨论了基于特征子图匹配的特征识别方法以及属性邻接图的分解。用此特征识别方法实现了中等复杂程度机械零件的特征识别。更多还原

【Abstract】 This paper studies the means that machining geometric features are extracted from STEP AP203 neutral file.Organization structure of STEP AP203 neutral file is firstly analyzed,then connection information between the surfaces is extracted from it and expressed.This paper discussed the theory and method of feature recognition and attributed adjacency graph decomposing.Feature recognition of mechanical parts in medium complex degree is realized by using it.更多还原
