Gd&t flatness with datum
WebThe GD&T Flatness symbol references how flat a surface is. It is not dependent on any other datums or features. Flatness is a form control, because it is used to control the form or shape of a feature. It controls how much a surface on a part may deviate from an ideal plane.

WebFeb 6, 2012 · ASME Y14.5 Paragraph 8.2: "Profile tolerances are used to define a tolerance zone to form combinations of size,form, orientation, and location of feature (s)..." Also: "Depending upon the design requirements, profile tolerance zones may or may not be related to datums." In my opinion, "design requirements" are not "inspection requirements". WebNov 16, 2024 · Similar to flatness, surface perpendicularity measures surface variation between two parallel planes. But unlike perpendicularity, flatness (like all other form controls) applies to a surface without a datum. Another difference is that perpendicularity controls the angle (90° with respect to the datum feature) while flatness does not. …

If a part is simply placed on a datum simulator (e.g. a high-precision granite flat) and then inspected, then the process will be the same. But of course, a part can pass a flatness check ...
