机床工作台平面度定位测量精度的研究

Research on Positioned Measuring Accuracy or Flatness of Machine Tool's Working Table

文中论述了机床工作台平面度用桥板测量的定位精度。阐明改进桥板结构，采取必要措施是提高桥板定位精度的有效途径，有益于提高机床工作台平面度测量的准确度。

The bridge plate is important tool for pitch measurment and directly effect on getting of measureddata and evaluation of the errors in flatness measuring.The research on positioned measuring accuracy of bridge plate is important to improve the measured accuracy by pitch method in measuring of table of machine tool.The paper discussed positioned accuracy ofthe table flatness measured by bridge plate. The necessary steps are taken to improve the bridge positioningaccuracy and accuracy of flatness measuring of the table.
