Agent-Based Precision Manufacturing Systems

这笔赠款提供了额外的资金，用于开发一个基于代理的系统，用于设计，工艺规划和精密铣削零件的制造。 将开发的代理包括软件包，其中包含与制造物理学或专门程序的重要方面的专门知识有关的信息、数据库和说明。 在这项工作中，主要的兴趣是开发算法，体现了过程的物理，这将允许最小化的残余应力，提高边缘质量和改善公差的精密机械部件铣削。 代理输出的结果将是对特定刀具路径或操作条件的微小调整，这将在“第一部分时间”方面做出可接受的牺牲，从而显著提高零件质量。“这项研究将定量地衡量生产速度和零件质量之间的权衡。 将进行实验，其中零件将制造具有高边缘质量和公差，并关注其他零件质量问题，如最大限度地减少表面下变形和残余应力。 代理将被集成到一个高端的CAD系统的详细设计，宏观和微观规划，刀具路径规划，和可制造性feedback.If成功的，这项研究的结果将导致新的软件功能，创造一个更广泛的基于互联网的代理为基础的制造系统。 该系统将特别包括精密加工改进的代理，并解决来自竞争代理的相互冲突的建议的问题。 我们的目标是表明，一个相当大的优势，在边缘质量和公差可以实现只有最小的牺牲，在生产时间相比，“正常”的过程规划。 最后，一个主要的重点将是解决代理人之间的冲突和代理人的意见和成本效益分析之间的权衡。 将制定部分以博弈论为基础的具体方法来解决这些冲突。

This grant provides additional funding for the development of an agent-based system for the design, process planning and manufacturing of precision milled parts. The agents that will be developed consist of software packages containing information, databases, and instructions related to specialized knowledge on important aspects of the physics of manufacturing or specialized procedures. In this work, the primary interest is on developing algorithms that embody the process physics and that will allow the minimization of residual stresses, enhancement of edge quality and improvement in tolerances in milling of precision mechanical components. The result of the agent output will be minor adjustments to specific tool paths or operating conditions that will make a considerable improvement in part quality with acceptable sacrifice in "time to first part." This research will measure this trade-off between production speed and part quality quantitatively. Experiments will be performed in which parts will be fabricated with a high edge quality and tolerance, and with concern for other part quality issues such as minimizing subsurface deformations and residual stresses. The agents will be integrated into a high-end CAD system for detailed design, macro and micro planners, a tool path planner, and manufacturability feedback.If successful, the results of this research will lead to new software capability creating a broader Internet-based Agent Based Manufacturing System. The system will specifically include agents for precision machining improvements and address issues of conflicting advice from competing agents. The goal is to show that a considerable benefit in edge quality and tolerance can be achieved with only minimal sacrifice in production time compared to "normal" process planning. Finally, a major focus will be on conflict resolution between agents and trade-offs between agent advice and cost-benefit analyses. Specific methodologies, based in part on game theory, will be developed to address these conflicts.
