| Abstract: | Twenty-one kinds of individual geometric errors which result in 3D measuring uncertainty of a coordinate measuring machine and the transmitting relations between each of them and 3D measuring uncertainty are discussed in the paper. The formula of 3D measuring uncertainty (U95=K1 +L/K2) will be given. Finally,an analysis example will be provided. This paper can give a guide for the development of coordinate measuring machine. |
