9412733 Tsao The objective of this research is to investigate the dynamic modeling and real-time control of machining processes, in particular drilling. This project will use mixed time domain and drill angle domain modeling for the drilling process, statistical time series canonical variate analysis techniques for identifying the multi-input and multi-output time-varying nonlinear process parameters, and robust adaptive feedback and feedforward algorithms for form tool drilling and high-speed drilling process control. In addition, this project will investigate the use of spindle and feed drive power or current in lieu of the drilling torque and thrust force as feedback measurements for cost effective factory implementation. The successful implementation of the project has the potential to significantly improve drilling quality and extend operating regimes. It could also provide a methodology for dynamic modeling and process control of other machining processes.

小行星9412733 本研究的目的是探讨加工过程的动态建模和实时控制，特别是钻削。 本计画将使用混合时域与钻削角度域的钻削过程建模，统计时间序列规范变量分析技术辨识多输入多输出时变非线性过程参数，以及强健的适应性回授与前馈演算法进行成形工具钻削与高速钻削过程控制。 此外，本项目将研究使用主轴和进给驱动功率或电流代替钻孔扭矩和推力作为反馈测量，以实现成本效益的工厂实施。 该项目的成功实施有可能大大提高钻井质量和扩大作业范围。 它也可以为其他加工过程的动态建模和过程控制提供一种方法。
