Plate thickness: the distance between … WebNov 23, 2024 · Remember: Parallelism does not directly control the angle of the referenced surface; it controls the envelope (like flatness) where the surface needs to be.The goal is to ensure all points are within a specified tolerance distance away from their corresponding datum points. In Fig. 5 below The surface of the part must lie between two parallel … WebWhat is Flatness Tolerance in GD&T? Flatness in gd&t is a type of foam control GD&T tolerance. It controls the variations in a flat surface, regardless of any datum feature. In this way, it ensures the controlled surface is flat enough to perform the required function. The flatness tolerance value is always less than the dimensional tolerance ... hyper cataracts
