基于工厂设计模式的产品加工信息提取

The Extraction of Product Machining Information Based on Factory Method Design Pattern

为了使CAM系统能直接准确读取CAD系统中与CAM相关的产品加工信息,应用IGES(In itial G raph ics Exchan-ges Spec ification)规范,提出一种基于工厂设计模式的加工信息提取框架。它并未采用硬编码方式,而是将几何实体的创建过程从客户端程序中分离出来,这就大大提高了该接口可组合性、可维护性以及可复用性,为解决集成制造系统的信息共享问题提供了一种实用方法。

A frame for machining information extraction was presented based on the initial graphics exchanges specification （IGES） and the factory method design pattern in order to get the machining information required in CAM system from CAD system. This approach adopts the method of separating the creation process of geometric entity from the client program instead of hard - coding, which improves the combinative, maintainability and reusability of this interface and provides a practical method to resolve the information sharing on CAD/CAM.
