在以平板为测量基准的平台测量中,往往遇到平板精度不能满足测量要求。如果将平板划分为若干区域,以其中一个误差足够小,区域足够大的位置,用作排除被测件基准表面形状误差的理想区域,就能提高测试精度。本文介绍一种平板分区法──整体座标法。方法简单,收效快。现简要介绍如 In the flat as the basis for measuring the platform measurement, often encountered flatness can not meet the measurement requirements. If the tablet is divided into several regions, one of the errors is small enough, the region is large enough to exclude the reference surface of the test piece shape error of the ideal area, can improve the test accuracy. This article describes a flat partition method ─ ─ overall coordinate method. The method is simple and fast. Now a brief introduction such as
