【摘要】 如何充分利用CAD中已有的零件信息是实现CAD与CAPP的信息共享,完成CAD/CAPP集成的关键问题之一.通过对AutoCAD的深层挖掘,充分利用AutoCAD中DXF文件对零件信息的表示,针对箱体类零件的特点,并利用关系型数据库技术的优点,以程序自动处理为主,辅以一定的人工交互输入,完成了对箱体类零件特征信息的合理描述及表示,为实现CAD/CAPP的无缝集成打下了数据基础.更多还原

【Abstract】 How to make full use of the information which has been described in CAD system is a central problem in realizing information share and integration between CAD and CAPP.This paper studies deeply AutoCAD system and its description about part information.It makes full use of DXF file in AutoCAD and the knowledge of RDBS(Relation Database System) and the character of box part.Then it realizes properly feature information description about box part which is finished by program automated realizing mainly and some degree of manual work.Finally,this research lays the foundation of CAD/CAPP integration smoothly.更多还原
