Abstract

The jig and fixture is important basic equipment in the machining process and mechanical assembly. With the development of the CAD/CAPP/CAM and the wide application of CNC technique in the manufacturing, the traditional method for the jig and fixture design has not adapted to the demands of complexity and variety in the practical production with update of products more and more rapid. Computer aided fixture design (CAFD) is an effective way for the situation. The designer's participation and experience are necessary for the traditional CAFD system. A new design system is developed in the article for the special purpose jig and fixture by applying artificial intelligence (AI) technology into the CAFD system, using the theory of the expert system and technology of the 3D modelling. It discusses the configuration, the general function modules, the knowledge representation, the reasoning mechanism and the standard component base of the jig and fixture. This paper explored the technology of intelligence and optimization in the process of the jig and fixture design. Finally, an example of virtual assembly is given designed by the CAFD system

智能夹具设计系统的开发

夹具是机械加工过程和机械装配中的重要基础设备。随着CAD/CAPP/CAM技术的发展和CNC技术在制造业中的广泛应用，传统的夹具设计方法已经不能适应实际生产中产品更新速度越来越快、复杂性和多样性的要求。计算机辅助夹具设计(CAFD)是解决这一问题的有效途径。传统的CAFD系统需要设计师的参与和经验。本文利用专家系统理论和三维建模技术，将人工智能(AI)技术应用于专用夹具设计系统，开发了一种新的专用夹具设计系统。讨论了夹具的结构、一般功能模块、知识表示、推理机制和标准件库。探讨了夹具设计过程中的智能化与优化技术。最后，给出了一个基于CAFD系统的虚拟装配实例
