基于AutoCAD的CAD/CAPP集成系统研究

Research of CAD/CAPP Integrated System Based on AutoCAD

鉴于国内外CAD/CAPP集成的现状,应用AutoCAD环境下的二次开发工具ObjectARX技术,能够和AutoCAD共享空间并直接和AutoCAD进行通信读取零件图形数据库中的几何和工艺信息,从而实现了零件二维图形信息的自动获取,并通过ADO数据库绑定技术完成了对数据库的写入、修改、查询等操作,避免了零件信息的二次输入和人工输入的错误,最终实现了CAD/CAPP的无缝集成。

In view of the integration actuality of CAD/CAPP, this paper uses the technology of ObjectARX, which can share the space and correspond with AutoCAD directly to get the geometry and craftwork information of parts automatically. Moreover, it uses the technology of ADO to complete the handle of writing date,the modification and the query of data. Therefore, it avoids the repeated information input and mistakes of input with hand, and realizes the integration of CAD & CAPP perfectly.
