Difference between Cylindercity and Circularity?

Question

Accepted Answer

Cylindricity refers to how closely a cylinder's surface conforms to a perfect cylinder, while circularity refers to how closely a circle's boundary conforms to a perfect circle.

Cylindricity is a 3D form tolerance that controls the overall form of a cylinder, including straightness, roundness, and taper.
Circularity is a 2D form tolerance that controls the roundness of a circle, ensuring that all points on the circle are equidistant from the center.
Cylindricity is used for cylindrical parts like shafts, while circularity is used for circular features like holes or bores.
Cylindricity is measured using a cylindrical tolerance zone, while circularity is measured using a circular tolerance zone.
