Roundness is the measure of how closely the shape of an object approaches that of a mathematically perfect circle. Roundness applies in two dimensions, such as the cross sectional circles along a cylindrical object such as a shaft or a cylindrical roller for a bearing.

According to the International Standard of Organization (ISO), roundness is defined as a ratio of inscribed and circumscribed circles radii. i.e. the maximal and minimal sizes for circles that are just enough to confine and form a particular shape.

2024年7月10日 · 在Halcon中，区域的特征Roundness（圆度）和Circularity（圆度）虽然都用于描述区域与圆形之间的相似程度，但它们在计算方法和应用上存在一些区别。 还是从帮助文档着手： 1、Roundness（圆度） 机翻： 计算方法：Roundness通常通过计算区域轮廓上各点到区域中心的 ...

英文：Circularity/ Roundness. 释义：理想的圆，有两种解释： ①非球体要素：在垂直于轴线的任意相交平面上，所有的圆周线上的点到轴线的距离相等的程度。 ②球体要素：在通过球心的任意相交平面上，所有的圆周线上的点到球心的距离相等的程度。

2024年7月14日 · Have you ever wondered what makes a perfect circle? In the world of mechanical engineering, roundness is a crucial concept that affects the performance and longevity of rotating components. This article dives into the intricacies of roundness, exploring its definition, measurement methods, and the factors that influence it.

Circularity vs cylindricity. Cylindricity serves as the three-dimensional equivalent of circularity. While circularity focuses solely on the roundness of a feature, cylindricity also addresses the straightness of the central axis of that circular feature. The aim of cylindricity is to ensure that the geometric form of the feature is as close to a perfect cylinder as possible.

When measuring roundness, you are measuring the roundness of a circular cross-section of a shaft, bore, or circular cone, to see how accurate a circle it is. The Easiest Way to Measure Roundness. 3D/GD&T Inspection by Anyone, Anywhere. Two-point measurement is performed on the outer form by dividing it into four to eight sections.

Roundness is defined in ISO 1101 as the separation of two concentric circles that just enclose the circular section of interest. Here is the video watch now for a better understanding of what is roundness.

2012年1月1日 · This paper introduces simple and efficient algorithms to evaluate the roundness error from the measured points using four internationally defined methods: Least Squares Circle (LSC), Minimum Circumscribed Circle (MCC), Maximum Inscribed Circle (MIC) and Minimum Zone Circles (MZC). ...
