轴类零件制造特征分类及特征信息模型

摘要

Several common characteristics of the shaft part were summarized by analyzing the process and characteristics of the shaft parts. The relationships between the 30 different characteristics, their coupling relationship and positioning were summed up,and detailed feature information were described. A u-nique feature information model described in XML format was established by feature modeling, the document in XML format was created to coordinate with postorder CAPP system to read the XML data.%通过分析轴类零件的工艺和特点,归纳出轴类零件的特征.总结出30种不同特征间的关系及其联结和定位关系.描述了详细的特征信息,建立了独特的、用XML格式描述的特征信息模型,并创建XML格式的文档,用以配合后序的CAPP系统读取XML文档数据.
