利用接口技术的基于OO的冲裁模CAD/CAM系统的建模

利用面向对象技术进行软件开发是目前软件开发的趋势。为了构建基于面向对象的冲裁模CAD／CAM系统，利用VB平台提供的接口技术，通过实现接口继承来实现类的继承性和多态性，并使用GUIDS方法层层深入地组织系统结构，最终以零件类为基类，建立了较为科学的系统模型。将该模型应用于应用软件的设计中可增强应用软件的可维护性和可扩展性。

With the interface technology realizing to build the system model of blanking dies of CAD/CAM on the OO-based

It is the tendency of the development of the software that using OO technology to design and develop the applied software. In order to establish the object-oriented system model of blanking dies of CAD/CAM on the VB platform, it is essential to use the inheritance which is supplied by the platform. But VB does not supply the realizing inheritance directly. Although it supports multi-morphology it has to run in low efficiency. In fact, these problems can be resolved when making use of the interface technology. The inheritance can be realized through realizing interface inheritance, and the multi-morphology can be improved. Using this technology and GUIDS method, it becomes reality to establish OO _based system. At last, the comparative scientific system model which making the part to be the base class was established, and through realizing this model, system realized the OO completely. At the same time, the maintenance and expansion of the application software were strengthened.
