I know that a circle has a circularity of nearly 1. As i understand the circularity is the roundness of an object / blob ? So my question is what the values greater 1 implicate? WebApr 1, 2024 · Circularity refers to how close the cross-section of the workpiece to the theoretical circle. When the difference between the maximum radius and the minimum radius is 0, the circularity is 0. 1. Circularity is a 2-dimensional tolerance zone, which consists of 2 concentric circles whose radius spacing is equal to the tolerance value.
