MECHANICAL DESIGN ENGINEERING – Geometrical Dimensioning and Tolerancing_What is the PERPENDICULARITY tolerance?

In a mechanical design of an assembly made up of various parts it is often the case to make sure the functional elements are perpendicular to a reference. In GD & T this is called Perpendicularity Tolerance. Like parallelism, the perpendicularity tolerance is also an Orientation tolerance from the sub-group of Direction tolerances. Therefore for … More
