摘要： 对机床产品协同设计过程及其特点进行研究，采用UML统一建模语言中的泳道图表示机床协同设计过程，提出了面向机床产品的协同设计支持环境的层次结构，该协同设计支持环境主要由3个方面的内容组成：对机床产品设计开发活动的支持、对设计活动单元组织和管理的支持、对设计活动单元间协同的支持。采用分布式为主、集中式为辅的方式，建立了面向机床产品的协同设计支持环境的体系结构，并对实现该体系结构的任务规划、协同约束模型、冲突消解等关键技术进行了研究。在此基础上，开发了面向机床产品的协同设计支持环境的原型系统。

Abstract: The process and characteristic of machine tool’s collaborative design are studied. The process of machine tool’s collaborative design is described by UML. Layered structure of collaborative design support environment for machine tool is proposed. Support for collaborative design activity, support for organization and management of collaborative design group, and support for cooperation of collaborative design group are the three main factors of the collaborative design support environment. The framework of the support environment is set up where distributed structure is mainly used and centralized structure is secondarily used. The key technologies of the system are investigated, including task scheduling, collaborative constraint model, conflict resolution, etc. With these technologies a corresponding prototype system is partially developed.

Key words: Machine tool, Collaborative design support environment, Constraint network, Conflict resolution
