| Abstract: | In this paper,every errors which have impact on measuring accuracy of measuring machine are analyzed in detail.The error correction modal is founded by the theory of homogeneous coordinate.21 geometric errors which have great impact on measuring accuracy are corrected by this modal.The transfer coefficients of every geometric errors are presented.The bottle-neck factors are found by means of assessing the three axes' uncertainty of measuring machine after correcting errors.The paper analysis the problems and presents the way to solve them.The correctness and practicability are proved by means of experiment.It has significant reference values to guarantee the accuracy of measuring machine. |
