Webis 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. WebThe ovality tolerance is considered to be a total spread, inside which both the maximum OD and minimum OD dimensions must fall. When a tube or pipe are bent the tube becomes more oval than round.
