《计量技术》90年第12期刊载了《圆柱角尺垂直度的测量及其误差分析》(下称《测量》),文中介绍了对一米或更大的圆柱角尺的垂直度进行精确测量的方法。笔者认为该方法似有不妥之处,提出来与大家商榷。 1.《测量》中是用两标准心轴组成60°～90°的V型角度,被测圆柱角尺紧靠心轴测量,如图1所示。但实际上,圆柱角尺的圆度 “Metrology Technology” No. 12, 1990, “Measurement and Error Analysis of Squareness of Cylindrical Angles” (hereinafter referred to as “Measurement”) is introduced in this paper. The precision measurement of the squareness of one meter or more cylindrical square is introduced method. I think this method seems to be inappropriate, put forward to discuss with you. 1. “Measurement” is the use of two standard mandrel 60 ° ~ 90 ° V-shaped angle, measured cylindrical square close to the spindle measured, as shown in Figure 1. But in fact, the roundness of the cylindrical square
