Intelligent Control of Machining of Composite Materials

该项目将探索开发定量模型来描述控制层压复合材料钻削损伤的关键参数，并将开发耦合这些模型的复合材料加工智能控制策略。基于分层的钻井模型将通过使用仪器工具和工件夹具以及应用声发射技术来检测这种损伤的开始来验证。将开发一种智能控制器来学习工艺中的关键参数，并选择最佳操作条件，以保持高生产率和高质量的成品。该项目很有可能对复合材料的加工产生重大影响。如果复合材料加工中的分层问题得到解决，复合材料的应用将会有很大的拓展。

This project will explore the development of quantitative models to describe the critical parameters that govern damage in drilling of laminated composites and will develop intelligent control strategies for machining of composites coupling these models. The delamination based drilling models will be validated by using instrumented tools and workpiece fixtures and applying acoustic emission techniques to detect the onset of this damage. An intelligent controller will be developed to learn key parameters in the process and select the optimal operating conditions for maintaining both a high production rate and superior quality of the finished workpiece. The project has a high potential to significantly impact machining of composites. If the delamination problem in composite machining is solved, the application of composites can be substantially widened.
