一、中等一维尺寸的测量一维中等尺寸是最基本的尺寸,它包括方形工件的长度、厚度、宽度、槽的深度、园柱体的轴径以及螺距等等,从测量原理可知,长度测量实质上是被测工件上的任一被测线的长度量和测量线上的标准量进行比较的过程。因而在长度测量时,被测线和测量线之间应有一定的方 First, the measurement of the medium one-dimensional size One-dimensional medium size is the most basic size, which includes the length of the square workpiece, thickness, width, depth of the groove, the cylinder shaft diameter and pitch, etc., from the measurement principle, the length The measurement is essentially the process of comparing the length of any measured line on the part under test with the standard amount on the measurement line. Therefore, the length of measurement, the measured line and the measurement line should have a certain square
