| Abstract: | Different from the common 4-point method for separating the form error motion of the workpiece from the motion error of the axis of rotation. It can reach higher rneasured precision by making use 4 - point method. This paper describes the measurement principle and characteristics of mechanical structure, optics-electric system, micro-sensor signal sample, and computer interface. |
