FIGURE 5.15 Internal rotational features. For rotational components, straightness, circularity (roundness), cylindricity, and angularity are considered. Surface finish and dimensional tolerances which are applied to single features (like diametric tolerance) are also included in this category. Attributing the tolerances to the surface features seems to be rational because the method is in agreement with the definition of the feature adopted (Figure 5.17).
