[St...] Posted March 6, 2025 Share Posted March 6, 2025 Would you consider this Concentricity? or Coaxiality? We are having a difference of opinion on this. Link to comment Share on other sites More sharing options...
[Cl...] Posted March 6, 2025 Share Posted March 6, 2025 Concentricity describes how close the axis of two cylindrical or circular features are to each other. IMHO. Link to comment Share on other sites More sharing options...
[Ke...] Posted March 6, 2025 Share Posted March 6, 2025 If the length of the cylinder is longer than 3 times the diameter, it is evaluated in terms of coaxiality. If the length is shorter than 3 times the diameter, or if there is an ACS symbol, it is evaluated in terms of concentricity. 3 Link to comment Share on other sites More sharing options...

[Gu...] Posted March 7, 2025 Share Posted March 7, 2025 I do not understand the difference between coaxiality and concentricity in your case ? I this case, I prefer check straightness of the 2 axis in combined zone because the datum A is too short. 1 Link to comment Share on other sites More sharing options...
[Da...] Posted March 7, 2025 Share Posted March 7, 2025 Concentricity applies looking down the center axis, coaxiality applies when looking at it from the sides. Link to comment Share on other sites More sharing options...

I am not an ISO expert in any regards, but I am looking forward to the comments from the ISO community on the ACS interpretation. I also don't understand why ISO coaxiality doesn't consider the outer tangential element condition of the considered feature. Link to comment Share on other sites More sharing options...
