本文提出了一种新的方法，即矢量示值法，用与主轴垂直的平面上的瞬时矢量来表示旋转主轴的径向误差运动。径向误差运动由彼此垂直放置的两个传感器测量。提出了一种通过数字处理获得主轴位移瞬时矢量的新算法。结果表明，矢量指示法比传统的“利萨图”法更能准确地反映主轴轴的位移特性。
In this paper, the authors present a new technique, called the vector indication method, which computes and illustrates the radial error motion of a rotating spindle as the instantaneous vectors on a plane normal to a spindle axis. The radial error motion is measured by two sensors located perpendicularly to each other. A new algorithm is developed to obtain the instantaneous vectors of spindle axis displacement by digital processing. It is revealed that the behavior of displacement of spindle axis can be more precisely known by the vector indication method than by “the Lissajous' figure,” which is one of the conventional methods.
