Cylindricity gd
WebCircularity tolerance in GD&T controls irregularities in cylindrical, spherical, or conical parts. It ensures all points on the plane of a circular feature are equidistant from the True central axis. Manufacturing a perfect circular feature is a very challenging and costly task. WebCylindricity in gd&t creates a 3-dimensional tolerance zone with two co-axial cylinders at a distance equal to the cylindricity control tolerance. In the above example, the radial distance between cylinders will be 0.1mm. Therefore all points of the surface to be controlled must lie within a defined 3D tolerance zone.

WebConcentricity is a related tolerance. Controlled Radius A radius that yields a circle, arc, or sphere with no flat sections or reversals. In GD&T, controlled radius occurs on a blueprint with the symbol CR. Coordinate Tolerancing A system for describing the design of a part that compares its features to distances along three linear axes.
WebCylindricity is the 3D version of roundness. It assesses how closely an object comes to a perfect cylinder, meaning that it is not only round, but also straight along its axis.
