摘要：
一个设计巧妙的CAPP系统能在CAD和CAM之间架起相互联系的桥梁 。许多最新设计的系统都是基于专家系统的。但是，由于过于复杂，在实际运用中，上述的许多系统在企业中都不能有效地运作。同时，现代的计算机集成制造系统要求CAPP系统在实际运用中具有良好的可扩展性和柔性。因此，仅仅只用一个大型的专家系统来构建工业CAPP系统是非常困难的。为了克服上述的缺点，本文提供了一种新的协同代理模型的设计方法。它具有以下优点：良好的独立性、柔性、通用性、模块性和可分离性。依据这框架我们特别设计了这种协同过程计划系统即机械协同CAPP来验证上述理论。它的系统模拟、代理结构设计、协作、协同和协同CAPP系统的结构研究将在下面介绍。

Abstract：
A well designed computer-aided process planning（CAPP）system bridges the gap between CAD and CAM. A number of systems have recently been developed relying on a stand- alone expert system. However, because of over-complexity, many such systems cannot be effectively applied to industrial enterprises in practice. Moreover, the modern computer integrated manufacturing system(CIM)requires the CAPP system to be extendible and flexible for practical industrial applications. It is hardly possible to develop the extensive industrial CAPP system by using only one large expert system. To overcome these weaknesses, a new cooperative agent model is presented for process planning in this paper that satisfies five major requirements: Autonomy, Flexibility, Interoperability, Modularity and Scalability. In accordance with this framework proposed, a machining cooperative process planning system(Machining CoCAPP)is specifically developed for demonstration purpose. The system modelling, agent structure design, cooperation and coordination mechanism, and case study of the Machining CoCAPP are presented.
