| Abstract: | In this psper, the evaluating scheme of positioning repeatability of the VNCMT is studied-out refering to the relevant contents of positioning accuracy of conventional NC machines and considering the characters of the VNCMT. The positioning repeatability of BKX-I model machine is evaluated according to the experiments. These tries may offer a reference for studies of such kinds of machine tools. |
