WebbIt measures the relative height between the lowest and highest points on a surface. This tolerance applies to an edge, axis of a revolution, or line on a surface. Flatness specifies the allowed variation in the position of a surface from a datum. It has a tolerance zone of a rectangle defined by two parallel planes separated by the tolerance value. Webbin 4 tolerance classes (f – fine, m – medium, c – coarse, v – very coarse). It applies for the linear dimensions and angular dimensions such as external sizes, ...
