Roundness refers to a condition of a circular line or the surface of a circular feature wherein all points on the line or on the periphery of a plane cross section of the feature, are equidistant from a common center point . Examples : Disc, Sphere , Cylinder, Cone Errors of Roundness Errors of Roundness
WebRoundness, or circularity, is the 2D tolerance that controls how closely a crosssection of a cylinder, - sphere, or cone is to a mathematically perfect circle. Consider a cylinder whose purpose is to roll along a flat surface. A small flat on the OD of the cylinder would detract from how smoothly the shaft can roll. WebSometimes circular surfaces are used for moving parts such as ball bearings or spools, in which case circularity helps ensure these parts move smoothly and wear evenly. Because circularity is applied to an …
