汽车纵梁数控冲床系统的数据库设计与开发

The Design and Developing for Database of NC Punch System of Automobile Frame

在分析AutoCAD数据交换文件的结构基础上,运用C++Builder语言实现了AutoCAD图形中实体信息数据库的建立,把获得的实体信息数据作为汽车纵梁数控冲床系统的加工数据。该实体信息数据获得方法的实现,为数控冲床系统的自动编程提供了简便快速的加工信息数据。

This thesis introduces a method on creating AutoCAD drawing entities information database and implement this method by using C^(++) Builder language based on analyzing the AutoCAD DXF file structure. This database is used the machining data of NC Punch system of auotomobile frame. The machining information data can be provided for the automatic programming of NC punch system by using the implementing method.
