钢球直径测量误差分析

Measuring error analysis of ball diameter

文中分析了在钢球生产和商品钢球检验中用对比法测量钢球直径时产生的误差,用空间解析几何推导出计算误差的公式。分析了钢球直径测量方法误差的性质及变化规律。附图2幅。

In this paper the analysis of error produced during measuring ball diameters with contrast method for ball production and commercial ball inspection is made.The calculating formula of measuring error is derived using spatial analytic geo metry.The variation rule & the characteristic of ball diameter measuring error are also analysed.
