Explain Cylindricity.

Question

Accepted Answer

Cylindricity is a geometric tolerance that describes the overall roundness and straightness of a cylindrical feature.

Cylindricity is a 3D tolerance that ensures a cylindrical feature is within a specified tolerance zone.
It measures the deviation of the surface of a cylinder from a perfect cylinder shape.
Cylindricity is often used to control the fit and function of cylindrical parts, such as shafts or bores.
It is represented by a cylindrical tolerance zone that envelops the entire cylindrical feature.
Cylindricity can be measured using specialized equipment, such as a coordinate measuring machine (CMM) or a roundness tester.

Accepted Answer

Cylindricity is one of the GD&T symbol that controls the circularity and straightness combined of a round part.
