摘要在飞机结构件的制造车间，设计变更和加工工艺变更伴随着飞机产品的整个开发周期。这种持续的变化代表了动态和集成设计和制造环境的典型特征。针对这种环境，本文提出了一种基于特征、Agent驱动的数控刀具轨迹自动生成方法。一个面向对象的协作框架来实现定义良好的加工功能，保持工程知识的刀具路径生成，和那些涉及的过程。代理用于协作控制、功能服务和域中介，以将设计和过程更改传播到加工特征。加工特征由代理激活，以自动做出适当的响应。基于特征的刀具轨迹生成原型已被开发，以验证所提出的方法。
AbstractOn the shop floor of manufacturing aircraft structural parts, design changes and machining process changes accompany the entire development cycle of aircraft products. Such constant changes represent a typical characteristic of a dynamic and integrated design and manufacturing environment. For such an environment, a feature-based, and agent-driven automatic numerical control tool path generation method is proposed in this paper. An object-oriented collaboration framework is employed to implement well-defined machining features which keep engineering knowledge about tool path generation, and those involved processes. Agents are used for collaboration control, function services and domain mediation to propagate design and process changes to machining features. Machining features are activated by agents to make the proper responses automatically. A prototype for feature-based tool path generation has been developed to verify the proposed method.
