WebMar 30, 2024 · The fourteen types of geometric tolerances in GD&T are divided into 5 main types of control. These are form, location, orientation, profile, and runout. Form controls determine the shape of individual features in a part. They consist of the following four types of geometric tolerances – straightness, flatness, circularity and cylindricity. WebAug 8, 2014 · Circularity: Describes how closely the object approaches the perfect shape of a circle and indicates the lack of any edges or corners on the part. Cylindricity: Describes how well a part adheres to a perfect cylinder. The tolerance is the 3D version of circularity. The next group focuses on the orientation of a surface or an axis: Webrectangle defined by two parallel planes separated by the tolerance value. Circularity is the allowed maximum deviation of a circle from a perfect circle. It measures the roundness of the cross-section of a part.
