Current research has established the validity of the approach to automated fixture design whereby knowledge for a single operation is represented in an expert system. The objective of the research is to extend the knowledge to incorporate a more realistic scenario, namely, fixturing for a sequence of operations. The internship is based on established work by the principal investigator in automated design of fixtures (AutoFix). It plans to redesign the system to carry out fixturing for a finite sequence of operations. The work will commence with knowledge acquisition from practitioners in industry. A system structure to handle multiple-optioned sets of heuristics (strategy, meta, and knowledge rules) will be developed. Knowledge on design of fixtures for multiple operations will be represented in a rule/frame structure. An existing computer-aided design (CAD) system interface will be incorporated. In automated design, this work will present a method of representing and handling complex design knowledge. This method may then be extended to other systems for mechanical design. The contribution to manufacturing research is more significant as this will greatly reduce fixture design and machine set-up times. It will lay the foundation for future research in this field of fixturing for a flexible manufacturing environment.

目前的研究已经建立了一个单一的操作知识表示在一个专家系统的自动夹具设计的方法的有效性。研究的目的是将知识扩展到一个更现实的情况下，即，夹具的一系列操作。实习是基于固定装置自动设计（AutoFix）的主要研究者的既定工作。它计划重新设计该系统，以便为有限的操作序列进行固定。这项工作将从从工业从业人员的知识获取开始。一个系统结构，以处理多个选项集（战略，Meta，知识规则）将开发。用于多个操作的夹具设计知识将以规则/框架结构表示。将纳入现有的计算机辅助设计系统界面。在自动化设计中，这项工作将提出一种表示和处理复杂设计知识的方法。这种方法可以推广到其他机械设计系统中。对制造研究的贡献更为重要，因为这将大大减少夹具设计和机器设置时间。这将奠定基础，为今后的研究在这一领域的夹具柔性制造环境。
