WebJun 2, 2008 · Source: Taylor Hobson Ltd. There are two generally accepted reasons why manufacturers measure roundness of components. The first is to sort nonconforming parts based on a customer-supplied blueprint before shipment to the customer; the second is to control the process tool with immediate feedback. WebIn GD&T, roundness or circularity are defined as the deviation of a nominally round component from a perfect circle. This page introduces the basic concepts before …

WebMar 21, 2024 · What Is Circularity? Our definition of circularity is: c = 4 π a p 2 where a is the area of a shape and p is its perimeter. It is a unitless quantity that lies in the range [ 0, 1]. A true circle has a circularity of 1. Here are the estimated circularity measurements for some simple shapes.
WebApr 1, 2024 · Circularity refers to how close the cross-section of the workpiece to the theoretical circle.
