These 14 tolerances can be categorized into five main groups: form, profile, orientation, location and runout. Perpendicularity is a type of orientation control. Orientation controls define the orientation of a feature with reference to a datum plane or axis.

All the points on the part surface must lie between the two planes for both callouts. The difference is that flatness is measured relative to itself and hence, works without a datum whereas the angularity tolerance references a datum. WebMar 18, 2024 · Straightness tolerance is a 2-dimensional GD&T callout that controls the straightness of part features. No axis can be perfectly straight. The goal is to ensure it is straight enough for the application. This callout sets a standard on how straight a feature must be along its length. Straightness can control two very different types of functions. the gristmill port clinton
