摘要
夹具是一种专用工具，用于在加工过程中准确、稳定地定位工件。适当的夹具设计，可以提高生产零件的质量，在许多现代制造业零部件中很流行。本研究结合基于规则的推理（RBR）和基于案例的推理（CBR）为主的综合性系统加工夹具的设计方法。在本文中，这种方法结合了规则和模糊综合评判法提出了推理合适的定位方案和定位功能。推理结果的基础上，提出了一种用于加工夹具设计的CBR方法。这种方法可帮助设计人员，参照先前的设计案例，迅速确定夹具方案。最后，建议系统的实施进行了概述和案例研究用来证明所提出的方法的适用性。


Applying RBR and CBR to develop a VR based integrated system for
machining fixture design
abstract
A fixture is a special tool used to accurately and stably locate the workpiece during machining process. Proper fixture design improves the quality and production of parts and also facilitates the interchangeability of parts that is prevalent in much of modern manufacturing. This study combines the rule-based reasoning (RBR) and case-based reasoning (CBR) method for machining fixture design in a VR based integrated system. In this paper, an approach combines the RBR and fuzzy comprehensive judgment method is proposed for reasoning suitable locating schemes and locating features. Based on the reasoning results, a CBR method for machining fixture design is then presented. This method could help designers, by referencing previous design cases, to make a conceptual fixturing solution quickly. Finally, the implementation of proposed system is outlined and cases study has been used to demonstrate the applicability of the proposed approach.
