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.

9409716 Zhuang 该奖项用于研究开发基于 Stewart 平台的机床结构自校准程序。 该研究将解决传感器位置和所需精度、用于校准目的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。 自校准技术如果成功，将可用于基于斯图尔特平台的新型计算机数控机床。 由于可以在不中断机器正常运行的情况下补偿各种类型的机器误差，包括由热梯度和负载变化引起的误差，因此这种机床的精度将得到提高。
