Perpendicularity of holes

WebApr 13, 2024 · Perpendicularity refers to the degree to which a surface, line, or axis is perpendicular to a specified datum plane or axis. It is used to control the orientation of features such as holes, shafts, and mating surfaces. Squareness refers to the degree to which two surfaces or features are perpendicular to each other.
