Webb7 nov. 2014 · I’m guessing by your post that it’s 2 mm. Also, the tolerance value given in the feature control is a total value and not a +/- value. The tolerance zone is two parallel planes separated by a distance as given in the feature control frame. The tolerance zone is oriented to your datum structure by a basic angle that has no tolerance. Webb9 apr. 2024 · There will always be variations in the parts being machined, and to indicate the tolerance for that variation, the designer may indicate the size tolerance in the drawing. However, since parts have geometric characteristics (shape, positional relationship, size, etc.) as well as size, size tolerances alone are not enough to convey design intent. sharmaine meaning in tagalog
