Research Initiation: An Autonomous Approach for On-line Calibration and Compensation of a New Class of Computer Numerically Controlled Machine Tools

9409716庄该奖项是为了表彰开发基于斯图尔特平台的机床结构自校准程序的研究。这项研究将解决传感器位置和期望精度、用于校准的系统运动学建模以及用于校准和补偿的最佳算法的设计等问题。如果自校准技术成功，将对基于斯图尔特平台的新型计算机数控机床有用。这类机床的精度将得到提高，因为各种类型的机床误差，包括由温度梯度和负载变化引起的误差，可以在不中断机器正常运行的情况下得到补偿。

9409716 Zhuang The award is for research to develop procedures for self- calibration of machine tool structures based on the Stewart Platform. The research would address issues of sensor location and desired accuracy, system kinematic modeling for purposes of calibration, and the design of optimal alogarithms for calibration and compensation. The self-calibration technique, if successful, would be of use to a new class of Computer Numerically Controlled machine tools based on the Stewart Platform. The accuracy of such machine tools would be improved as various types of machine errors, including those induced by thermal gradients and load variations, can be compensated for without interrupting normal machine operation.
