Geometric tolerances include straightness, flatness, circularity and Cylindricity and orientations of shapes such as angularity, parallelism and perpendicularity. Run-out relates to radial features and reference axes and
The flatness tolerance zone is a 3D tolerance zone, meaning that when you are checking flatness of a surface, you are checking the amount of variation up and down the y-axis over the entire plane. Figure 2 shows the tolerance zone for the surface flatness called out in the drawing in Figure 1. Figure 2: … See more Surface flatness is the type of flatness that most people are familiar with. On a drawing, the flatness callout can point straight to the surface with a leader arrow or be extended out from the surface and away from the … See more Flatness of a Feature of Size (FOS) is shown using the same flatness symbol used for a surface’s flatness.
