[Da...] Posted July 28, 2021 Share Posted July 28, 2021 You're still at straightness of an axis. You don't need to smooth the derived median line to evaluate the straightness. The full form error must be evaluated. But other than for straightness evaluation the derived median line is also used to define the direction of the local sizes. If you have a derived median line that is not "tangent continuous", you will run into a problem, because you can't make a perpendicular local size at the imperfect parts of the line. See my attachment for what a tangent continuous line is. If the derived median line is not tangent continuous, you have to smoothen the line to calculate a local size direction even at those places of the line that are flawed. That's all there is. So, in answer to your straightness #1 vs. #2, why do you need a smoothed line: You don't, and I never said you do. Not for straightness, only for local sizes! If I could make drawings half as good as you, I would have made one already. Hope you still understand what I mean.Dok4.pdf Link to comment Share on other sites More sharing options...

[Da...] Posted July 29, 2021 Share Posted July 29, 2021 Please sign in to view this quote. Ist schon okay. Aber ich habe absolut kein Interesse, irgendwen zu verarschen, und ich hab den Begriff auch noch erläutert und mit Zitaten belegt. Würde natürlich wahnsinnig gerne die gesamte Norm posten, aber das geht natürlich nicht. Link to comment Share on other sites More sharing options...
