三坐标数控机床的几何误差参数辨识

Error Parameter Identification for 3-axis NC Machine Tools

在分析了国内外误差参数辨识的现状之后,详细介绍了9线法的辨识原理,并以三坐标数控机床为例,运用9线法对三坐标数控机床的21项误差进行了辨识。

Based on the analysis of the status quo of the error parameter identification at home and abroad, the nine-line method is presented in detail. With a 3-axis NC machine tool taken as an example, the identification process for 21 errors existing in the machine tool is performed with the help of the nine-line method.
