By choosing the right class (hint: start with ), you avoid paying for unnecessary precision on non-critical angles. And by understanding the leg-length rule, you won’t accidentally request aerospace tolerances on a simple sheet metal bracket.
need to ensure that their processes can achieve the specified tolerances. This might require specific machine tools or measuring equipment. iso 2768 angular tolerance
The tolerances are in . They are angular deviations , not linear deviations. By choosing the right class (hint: start with
If you have ever sent a 2D drawing to a machine shop and received a call asking, “How tight do you actually need this chamfer to be?” — you have experienced the gap between "design intent" and "manufacturing reality." iso 2768 angular tolerance
