在机械加工及测量过程中 ,直尺作为精密的基准工具必不可少。直尺的修复主要依赖传统的手工刮削方法获得很高的形状和位置精度。文章介绍了在缺乏高精度制造和测量基准的条件下 ,利用作图 -计算法 ,制造出满足一级精度要求的直尺。
Straightedges are essential as precision reference tools in machining and measurement. Ruler repair mainly rely on the traditional hand scraping method to obtain high shape and position accuracy. This article introduces the use of drawing - calculation method to create a ruler to meet the first - order accuracy in the absence of high - precision manufacturing and measurement standards.
