在当前批林批孔运动深入发展的大好形势下,我厂广大职工焕发出“争、创、干”的革命精神,自己动手造设备、造工具,在制造弯尺(直角尺)时遇到没有标准测量工具的困难,经过工人,技术人员研究,采用三个弯尺互研法,解决了这个难题。现介绍如下,供大家参考。三个弯尺互研,就是用三个弯尺为一组,互研、互检,直到三个尺彼此都能很好地重合,都达到90°的要求。怎样用三弯尺互检法,求出每个尺的偏差数值呢?只要我们测出每两个尺相对检查时的缝隙值(上叉口或下叉口 Under the current favorable situation of further development of the “Confucianism and Criticism of Pok Pik Kong Movement”, the vast majority of our workers have glowed a revolutionary spirit of “striving, creating and doing” to create equipment and tools of their own, which they encountered when manufacturing curved ruler (rectangular) Without the difficulty of standard measurement tools, after workers, technicians to study the use of three cross-foot study method to solve this problem. Now introduced as follows, for your reference. Three cross-foot research, is the use of three for a set of foot, mutual research, mutual inspection, until the three feet are well coincident with each other, have reached 90 ° requirements. How to use the three-foot mutual inspection method, find out the value of each foot deviation? As long as we measure the relative inspection of each two feet when the gap value (upper or lower fork
