| 摘 要： | 圆锥孔径的测量往往比较困难、且精度较低。提出长度测量仪器与环规配合使用,应 用比较测量的方法检测圆锥孔的直径。通过计算和分析可以得出,当被测圆锥孔径不大于180 mm 时,其测量不确定度可小于1.84 μm。给出了测量方法和不确定度计算公式供操作时参考。

| Abstract: | When a length gauge is used together with a ring gauge to relatively measure the diameter of taper bore, through computation and analysis. It can be determine that the indefinition is less than 1.84 μm if the diameter of taper bore come up to 180 mm.The measuring method and computing formula are introduced in the paper. |
