数控机床几何误差参数辨识

STUDYING ON THE PARAMETER IDENTIFIOATION OF GEOMETRIC ERRORS FOR NO MAOHINE TOOLS

讨论一种改进型的数控机床几何误差参数辨识方法，所有的数学模型在ＸＨ７１４加工中心上得到验证方法适合于三坐标机床如加工中心、坐标测量机等的几何误差参数辨识．

An improved 22--line method of parameters identification for geometric errors of NC machine tools is discussed. All models are verified by a series of experiments on XH714 machining center. This method is available to identify geometric error parameters for three-coordinate equipment such as NC machining center and CMM.
