REG: The Development of a Real Time Active Chatter Control

亚利桑那大学航空航天和机械工程系将购买一台惠普3566A个人电脑频谱分析仪，该分析仪将致力于支持工程研究。该设备将用于几个研究项目，特别是包括开发实时主动颤振控制器。建议从分析和硬件两个方面开发机床颤振实时控制的必要技术，并以一种允许集成到现有数控机床的方式实施该系统。为了实现这一目标，研究将集中于开发各种金属加工机床在充分发展的颤振状态下运行时，实时识别刀具和工件之间的传递函数的技术。开发一种自适应闭环控制策略(基于实时系统辨识技术提供的数据)，以最小化刀具和工件之间的运动。最初的研究将侧重于车床振动，未来将扩展到更广泛的机床类别，包括(但不限于)铣床和平面磨床。*//

The Department of Aerospace and Mechanical Engineering at the University of Arizona will purchase an HP 3566A PC Spectrum Analyzer which will be dedicated to support research in engineering. The equipment will be used for several research projects, including in particular the development of a real time active chatter controller. It is proposed to develop both analytically and in hardware the necessary techniques for the real time control of machine tool chatter and to implement this system in a manner that allows for integration into existing CNC machine tools. To accomplish this objective, research will focus on development of techniques for real time identification of the transfer function between the cutting tool and the workpiece for a variety of metal working machines as the machine tool operates in the fully developed chatter regime. Development of an adaptive closed-loop control strategy (based on the data provided by the real time system identification technique) for minimizing the motion between the cutting tool and the workpiece. Initial research will focus on lathe chatter with the extension to a more broad class of machine tools, including (but not limited to) milling machines and surface grinders, in the future.*** //
