圆度是评定形状误差的主要几何量之一,圆度误差是评定产品加工质量的重要参数。本文提出了一种基于圆心搜索算法评定圆度误差的方法,应用最小二乘原则,详细阐述圆心搜索算法的计算过程与算法思路,并通过真实数据验证该算法的效果。基于接触式影像仪软件开发平台,利用C++语言设计出圆度误差评定软件,能够快速求出圆度误差值,为现场检测提供方便。

Roundness is one of the main geometric parameters for evaluating shape errors,and roundness error is an important parameter for evaluating product processing quality.This paper proposes a method for evaluating roundness error based on the center search algorithm.The calculation process and algorithm ideas of the center search algorithm are described in detail using the least square principle,and the effectiveness of the algorithm is verified by real data.Based on the contact imaging instrument software development platform,a roundness error evaluation software is designed using C++language,which can quickly calculate the roundness error value and provide convenience for on-site testing.
