Flatness vs profile tolerance

WebTrue position theory is the concept of indicating geometrical characteristics ( true position, profile, and angularity) using theoretically exact dimensions (TED). The theoretically exact dimensions are written in rectangular frames while the tolerances concerning that position are written in feature control frames.

WebMar 18, 2015 · Form tolerances control straightness, flatness, circularity, and cylindricity. When specifying a form tolerance, consideration must be given to the control of form already established through other tolerances such as size (Rule #1), orientation, runout, and profile controls. See para. 2.7 and Fig. 2-6. WebThe flatness tolerance zone is visualised as two parallel planes, spaced apart by the number indicated in the flatness control. ... Flatness vs profile of a surface.
