外文摘要：In order to improve the positioning accuracy of the machine tool, the position errors compensation is performed on the three-axis vertical machining center. It is noted that the angular errors and straightness errors of X, Y and Z axes of the machine tool are affected by the position errors. Taking Z-axis position errors compensation as an example, the high-precision laser interferometer and ball bar are used to measure the positioning error, angular errors, straightness errors and squareness error before and after Z-axis position errors compensation, and the results are discussed and compared. The results show that with the improvement of the positioning accuracy of the machine tool, the angular errors and straightness errors also improve, but the impact on the squareness error is not significant. There are not any reports on the results in this regard, and further theoretical analysis will be reported later.
