在圆刻度机和光栅盘检验仪等精密仪器中应用一种变态V形轴系(又称V弧轴系),本文介绍了此种轴系角晃动的测定和数据处理,叙述了用三表法测定径向晃动的原理和计算方法,这种方法可以实现伴测件圆度误差和被测轴系径向晃动的误差分离,还介绍了对三表法测量径向晃动的验证工作。文章中还列举了测定数据,计算了这两种晃动的单圈综合晃动量、多圈平均晃动量、双周晃动量及随机晃动量。
In the circular scale machine and grating disk tester and other precision instruments used in a metamorphic V-axis system (also known as V arc axis system), this article describes the determination and data processing of such shaft-axis sway, describes the use of three tables Method is used to determine the principle and calculation method of radial sway. This method can realize the error separation between the circularity error of the measured part and the radial sway of the measured shaft system. The verification of measuring the radial sway by the three-table method is also introduced. The article also enumerates the measurement data and calculates the total amount of unidirectional laps, the average amount of laps of multiple laps, the amount of bi-weekly wobbles and the amount of random shakes of the two wobbles.
