WebCylindricity specifies the roundness and straightness of a form. When measuring cylindricity, you are checking for distortion in the cylinder, to verify the accuracy of its cylindrical form. Sample Drawings. Using a … 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. The simplest example that demonstrates the need for cylindricity is a pin which is required to pass completely through a bore with a tight diametral tolerance.

WebHole diameter at the top and bottom should be nearly equal – in order to ensure a good fit with the bolt. One critical parameter that affects cylindricity of the hole is cutting speed.
