WebUse of Slots – A GD&T Example. As we saw earlier, slots allow us to avoid overconstraint while having greater precision. An example of this can be seen in Figure 3. Figure 3. Part with slot tolerances applied (Primary datum feature A is the flat plane at the bottom – Not Shown) Primary datum feature (A): The flat plane at the bottom of the ... WebA composite tolerance specifies two tolerances for the same geometric characteristic of a feature or for features that have different datum requirements. One tolerance relates to a pattern of features and the other tolerance to each feature within the pattern. The individual feature tolerance is more restrictive than the pattern tolerance
