本文提出的数据处理方法,是在测量轴线直线度和圆跳动(或圆度)的基础上,通过对实际轴线进行转换,确定其理想轴线,并按最小条件来评定圆柱度误差。一、原理简述设被测零件如图1所示,O—O连线为测量回转轴线,F_A、F_C及F_B分别为零件两端及中间三个截面的轮廓。由于实际轴线可能有弯曲、扭曲和各截面不相同的形状误差,三个截面轮廓的实际圆心都不一定和

The data processing method proposed in this paper is based on the measurement of axial straightness and circularity (or roundness), and the actual axis is converted to determine its ideal axis, and the cylindrical error is evaluated according to the minimum conditions. First, the principle outlined Let the measured parts shown in Figure 1, O-O connection for the measurement of the axis of rotation, F_A, F_C and F_B, respectively, both ends of the part and the middle of the three cross-sectional profile. Since the actual axis may have bending, twisting and shape errors of different cross-sections, the actual center of the three cross-sectional profiles is not necessarily
