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. WebbBroadly classified, there are two approaches to drawing designs: size tolerance and geometric tolerance. Size tolerance regulates the size of each dimension. Geometric tolerance regulates the shape, parallelism, tilting, position, run-out, and other factors. Size tolerance drawing Geometric tolerance drawing
WebbIt may be used to control just the size and shape of a feature or the size, shape, orientation, and location of an irregular-shaped feature. The profile tolerance controls the orientation and location of features with unusual shapes, very much like the position tolerance controls the orientation and location of holes or pins. WebbThe standard form of straightness is a 2-Dimensional tolerance that is used to ensure that a part is uniform across a surface or feature. Straightness can apply to either a flat feature such as the surface of a block, or it can apply to the surface of a …
