WebGeometric 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 features that are 90 o to a reference axis. ASME (ANSI) Y14.5M is the standard for dimensioning practice in the USA. Webflatness tolerance ; ISO 8062 covers the following tolerances: dimensional tolerances ; combined roundness, parallelism, perpendicularity and symmetry tolerance ; concentricity tolerance; straightness tolerance − flatness tolerance; Dimensional tolerances cover tolerances for dimensions in one die half and dimensions over parting line.

Flatness vs perpendicularity

WebAug 19, 2009 · Perpendicularity on a flat surface also includes flatness. In other words, if one had a .010 perpendicularity tolerance in the feature control frame, it means that when one measured the full surface set up on 90 degrees, we should not have a dial indicator movement of more than .010. It can be all angle (indicator increases/decreases as it is ... WebOct 12, 2024 · When measuring the perpendicularity of the end cut on parts, the results will also vary depending on the manufacturing method used. For example, with lapped parts, Metal Cutting can hold 0.0002″ over 0.125” diameter, or 0.1º. With the secondary operations that we perform, we might also need to take perpendicularity into consideration.
