摘要/Abstract

摘要： 为了解决国内机床导轨安装表面平面度检测无法实现数字化描述这一问题，基于变尺度原理，提出了全新的机床导轨安装面平面度误差检测方法，通过将多段具有重合区域的短安装面拼接起来实现安装表面全长测量.同时设计出了检测仪，给出了测量原理，利用基准板、测量仪和机床导轨安装表面间的几何关系，建立了算法的理论模型，开发出机床导轨安装表面平面度误差轮廓重构算法，并对算法进行了仿真.结果表明，算法可以精确重构出机床导轨安装面平面度误差轮廓.

Abstract: In order to solve the problem that the flatness measurement of the installation surface of machine tool guides in China cannot be digitally described， a new method of flatness error detection of the guide rail mounting surface of numerical control machines was proposed based on the mutative scale theory， whereby the total length of the mounting surface can be measured by splicing several short mounting surfaces with overlapping areas. The new instrument was designed and the measurement principles were made. The theoretical model of the algorithm was established by utilizing the geometric relationship between the reference plate， the measuring instrument and the installation surface of the machine tool guideway. And an algorithm for reconstructing the flatness error profile of the installation surface of the machine tool guideway was developed and simulated. The results demonstrated that the algorithm can reconstruct the flatness error profile of machine tool guides’ installation surface accurately.

Key words: flatness, mutative scale theory, digital detection, stitching measurement, profile reconstruction algorithm
