WebJun 9, 2008 · Callout: Hole Termination. I don't think this is defined in any standard, so I wanted to check here. I have a machined hole that requires a flat bottom, but I do not feel a section view is required for it. In the past I have used the counter-bore symbol to define a flat-bottomed hole without trouble. WebFlatness, in GD&T, is a measure of how closely a given surface is to a perfect 2D plane. That plane can be at any angle in 3D space and need not be a horizontal plane. …

WebSep 23, 2016 · Thus 0.001 in/in is incorrect, that would be a straightness specification. It should be 0.001 inch per 1x1 inch. It is somewhat difficult to compare a total flatness and unit flatness, you have to work out the worst case surface allowed by the per unit tolerance. It will be more than just the flatness per unit multiplied by the size.
