在主轴计量的现行标准中，径向探头测量的基本分量被认为是安装的测试工件的径向行程（偏心），基本径向误差运动被视为不存在。本文的主要目的是：（1）证明主轴径向运动基本误差的存在;（2）提出一种新的二维主轴径向运动误差测量分析方法;（3）讨论现有主轴运动分析方法的局限性。在2D框架中，径向误差运动是与应用无关的几何特性，因此与主轴应用中的径向误差运动的后果分开。2D方法不仅可以确定旋转轴径向误差运动，而且还可以确定所有类别的主轴应用中的误差运动的后果，包括具有两个径向敏感方向的一类新的主轴应用。相比之下，当前标准中规定的径向误差运动值给出了两类主轴应用中的径向误差运动的结果，但并不代表径向误差运动本身。新方法分为两部分。第一部分主要介绍二维方法的原理和实例。第二部分介绍了球轴承主轴和空气静压轴承主轴的实验结果。
In the current standards of spindle metrology, the fundamental component of radial probe measurement is considered radial throw (eccentricity) of the installed test artifact and the fundamental radial error motion is treated as non-existent. The goals of this paper are: (1) to make evident the fact that fundamental radial error motion can actually exist; (2) to present a new two-dimensional (2D) method to analyze spindle radial error motion measurement; (3) to discuss the limitations of current spindle motion analysis methods. In the 2D framework, the radial error motion is an application-independent geometric property and thus separate from the consequence of radial error motion in spindle applications. The 2D method can not only determine the axis of rotation radial error motion, but also the consequence of error motion in all classes of spindle applications, including a new class of spindle applications with two radial sensitive directions. In comparison, the radial error motion values specified in current standards give the consequence of radial error motion in two classes of spindle applications, but do not represent radial error motion itself. The new method is presented in two parts. Part 1 focuses on the theory and illustration of the 2D method. Part 2 presents the experimental results of a ball bearing spindle and an aerostatic bearing spindle.
