Machine tools with two rotary axes to control the orientation of a tool or a workpiece are collectively called five-axis machine tools. They play a key role in process integration for higher manufacturing efficiency. The objective of this research is to develop a methodology to "self-optimize" the motion accuracy of five-axis machine tools, where motion errors of five-axis machines, as well as errors in the machine setup, are measured by the machine itself and then compensated for. A vision-based measurement system for linear axis motions errors, and the R-test measurement system for rotary axis motion errors, were developed. A software to diagnose error causes, and then to numerically compensate for them, was developed.

具有两个旋转轴以控制刀具或工件方向的机床统称为五轴机床。它们在提高制造效率的过程集成中起着关键作用。这项研究的目的是开发一种方法来“自我优化”五轴机床的运动精度，其中五轴机床的运动误差以及机床设置中的误差由机床本身测量，然后进行补偿。研制了基于视觉的直线轴运动误差测量系统和旋转轴运动误差R检验测量系统。开发了一种诊断误差原因并对其进行数值补偿的软件。
