| 摘要: |
| 利用坐标测量法对V型块角度进行了测量。结果表明，虽然坐标测量法的测量精度比正弦法测量精度低，但在测量时所用的测量基准与加工基准保持一致，且剖面加工质量对测量精度影响较小，坐标测量法是V形块角度测量的最佳方法。 |

| Abstract: |
| Angels of V block were measured by means of coordinate method. The result shows that the measuring accuracy of coordinate method is not as good as that of sine measurement method. However, due to conformance of measuring and processing reference as well as little influence of processed quality of section to measuring accuracy, the coordinate method proves to be the best solution to measure V block. |
