A clear reference is necessary for specifying a target’s orientation tolerance, location tolerance, and profile tolerance —that clear reference is the datum. A datum is a theoretical, ideal feature such as plane, line, or point, which does not actually exist: this makes it difficult to understand.

WebNov 26, 2024 · A diameter symbol (⌀) signifies a diametric zone (cylindrical tolerance zone). To specify a spherical zone, the symbol is the letter ‘S’ followed by the diameter symbol (⌀). In the absence of a symbol, we assume a total wide zone. The second symbol in the 2nd block gives the value of the tolerance zone in mm. WebJun 3, 2024 · Cylindricity (GD&T) Explained. The GD&T standards in ASME Y14.5 -2009 define fourteen types of geometric tolerances. These fourteen geometric tolerances are divided into 5 main types of geometric control. These are form, location, orientation, profile and runout. Form controls determine the form of individual part features. farnborough gb
