| 摘 要： | 在详尽分析图形自动编程关键问题－实体建模的基础上，针对广大中小型企业自身特点及其加工对象的特殊性，提出一种新的三维形体表达方式及共数据库存储方法：内部采用特征造型以建立形体的数据库；外部采用三视图加轴侧图以完成详细几何信息的输入。这种方法为图形自动编程系统后续环节的方便连接奠定了坚实的基础。

| Abstract: | On the basis of a detailed analysis which is conducted into a critical problem--solid construction in the graph auto programming system, a new representation form of three dimension structure and its data storage are proposed,which are aimed at the particular requirements of the common middle or small scale enterprises to machine workpieces.A feature modelling is adopted to build up the data storage of structure within the system.Three view projection drawing and axonometric drawing are displayed on the monitor to facilitate to input the necessary geometric information.The method provides fundamentals for the post procedure to link up the modelling system. |
