晃动测量是用百分表代替精度较高的内径千分表、块规等测量工具,来测量各种中小孔径、槽宽、孔的椭圆度、圆锥度以及某些用一般量具较难测出的内尺寸、间隙值的一种测量方法。在工作现场缺少精密量具时也适用,而且比较经济。 一、晃动测量的原理和计算 由图1可见,在被测孔(或槽 Rocking measurement is the dial indicator instead of high precision dial gauge, block gauge and other measuring tools to measure a variety of small and medium size, width, hole ovality, conicity and some of the more difficult to measure with the general gauge A measure of the internal dimensions, gap values. The lack of precision gauges at the job site also applies and is economical. First, the principle of rocking measurement and calculation can be seen from Figure 1, measured hole (or groove
