部标准《金属切削机床检验通则》(JB2670—82)规定部件直线度误差用两端点连线法计算。木文介绍应用PC—1500微型计算机按两端点连线法计算直线度误差的程序设计。它以一组光学准直仪测得的直线度误差格数作为原始数据读入,经过计算机把离散型的原始数据进行处理,输出评定 Standard “metal cutting machine tool inspection General” (JB2670-82) provides parts straightness error using two end connection method. This paper introduces the program design of calculating the straightness error by PC-1500 microcomputer according to the connection method of two ends. It uses a set of optical collimator measured the number of straightness error as the original data read into the computer through discrete raw data processing output evaluation
