平板是生产工艺过程中一个重要的检验工具,一般对它的精度要求很高。平板检定的方法应按国家标准计量局制定的“平板检定规程”(JJG117-78)进行。本文介绍如何使用微型计算机来处理平板检定数据,从而有效地提高平板刮研精度,并大大提高工作效率。一、平板检定内容 1.平板检定内容平板检定的内容可分为两个部分。一是应用小角度仪器(如平直仪、自准直光管、水平仪等),按一定的布点和方向逐点测量平板表面,用两端点连接法计算各点的直线度误差;二是数据处理,根据各点的直 Flat plate is an important testing tool in the production process, and its accuracy is generally high. Plate test method should be developed by the National Bureau of Standards “flat test procedures” (JJG117-78). This article describes how to use the microcomputer to process the plate verification data, so as to effectively improve the precision of the plate scraping and greatly improve work efficiency. First, the flat test content 1 flat test content flat test content can be divided into two parts. First, the application of small-angle instruments (such as collimator, self-collimator, level meter, etc.), according to a certain point and direction of the measurement plate surface, using the two-end connection method to calculate the straightness error of each point; the second is the data Processed, according to the straight points
