一种小展角圆弧样板的检测方法

A kind of messureing method of small unfold angle arc model

从分析传统的以半径误差作评定标准来评定圆弧样板的方法在应用于小展角大圆弧时出现的问题入手,认为此类方法对小展角圆弧的评定效果不理想。并提出一种精确可行的在小展角条件下标定圆弧样板的方法。

This article start with analysis the problem of the traditional method from using radius error as evaluate standard to evaluates arc of model when apply it to the great circle arc with small unfolds angle. Thought the effect of using this kind of method to evaluate the arc with small unfold angle is not ideal. And proposed a kind of accurate and feasible method of evaluate arc model under the condition of small unfold angle.
