一、问题的提出三座标测量机问世以来,它以高效率和与数控加工制造一体化相匹配的优点而获得了迅速地发展和广泛的应用。但现在的三座标测量机欲想满足高精度测量要求,却受到了本身结构固有的阿贝误差的缺陷和基准元件的固有误差的限制。为此所谓的万能型( First, the question raised Three-coordinate measuring machine since its inception, it has high efficiency and integration with numerical control processing and manufacturing to obtain the advantages of rapid development and extensive application. However, the current three-coordinate measuring machine wants to meet the requirements of high-accuracy measurement, but it is limited by the inherent Abbe error of its own structure and the inherent error of the reference component. So-called universal type (
