现今的卡尺,主要是游标卡尺。它是应用游标原理对其刻度细分。本文简述此卡尺的几个技术问题游标卡尺的刻度细分原理游标卡尺的主尺刻度是等分刻度,通常以1mm等分的,对1mm 以下的细分是以一副尺上两条相邻刻线间距 b 与主尺上两条相应刻线间距 a 的差值来表示刻度的最小细分的值即分度值 i,而且 i 极必为a 的 n 等分,即i=a/n(n—整数),所以 b 与 a
Today’s calipers, mainly vernier calipers. It is the application of the principle of the cursor subdivision of its scale. This article describes some of the technical problems of calipers Vernier calipers scale subdivision principle Vernier calipers of the main scale scale is divided into equal parts, usually 1mm aliquot, subdivision below 1mm is a pair of ruler on two adjacent engraved Line spacing b and the main ruler on the two corresponding groove spacing a difference between the scale to represent the smallest subdivision value that sub-degree value i, and i must be a n n points, that i = a / n ( n-integer), so b and a
