Circularity roundness
WebFeb 12, 2024 · Circularity is a form constraint that measures how well the shape of a part matches a perfectly circular shape. This constraint is sometimes referred to as roundness. It is a two-dimensional tolerance control that is applied to circular cross-sections. The circularity of each cross-section is evaluated independently. 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 …
