Cylindricity is different from circularity, which is a two-dimensional measurement of roundness at only one point — a cross section — on a cylindrical part. It is also different from concentricity, which compares roundness at two different points or compares an outside diameter and an inside diameter (OD and ID).

Abrasive grains on grinding wheel are random in many aspects, such as shapes, attitudes, and positions. The randomness of grains influences greatly in the performance of grinding processes, and it ...
