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. … http://www.safss.msu.edu/fundamentals_of_gd_t/618~

WebA datum is a theoretical, ideal feature such as plane, line, or point, which does not actually exist: this makes it difficult to understand. Nevertheless, the understanding of datums is a … Webu/IdealisticAfrican has it right. The datum is a theoretical reference, but the physical surface will not have the flatness of a perfect datum. You'll need to tell the machinist just how close to the datum the surface needs to be. All three measurements are non-redundant. The first flatness tells you how flat the surface at the datum needs to be. qqq ticker ytd
