[ZE...] Posted March 27, 2018 Author Share Posted March 27, 2018 A diameter isn't flat, at least not in Europe, But I have been tricked before, the earth was flat at one point... Use roundness or waviness depending on your requirement. Eric Moberg | 03-27-2018 11:32 AM | Link to comment Share on other sites More sharing options...
[ZE...] Posted March 27, 2018 Author Share Posted March 27, 2018 Eric,,flatness, means surface face(plane). in general..f.y.i abdullah alghnaim | 03-27-2018 12:30 PM | Link to comment Share on other sites More sharing options...
[ZE...] Posted March 27, 2018 Author Share Posted March 27, 2018 No, flatness means flatness. It does not mean surface plane. Flatness is applicable to a plane though. If you formulate your question so it is understandable I'm sure you will receive better help. Eric Moberg | 03-27-2018 12:53 PM | Link to comment Share on other sites More sharing options...
[ZE...] Posted March 27, 2018 Author Share Posted March 27, 2018 Abdullah, I'm with Eric, when you say "FLATNESS ON A DIAMETER", the characteristic "FLATNESS" implies a PLANE feature. And, "DIAMETER" implies the feature is a circle, cylinder, cone or sphere feature. So, something in your question is not correct. Maybe a sketch or drawing showing what you're trying to check would help. Tom Oakes | 03-27-2018 01:35 PM | Link to comment Share on other sites More sharing options...
[ZE...] Posted March 27, 2018 Author Share Posted March 27, 2018 I'm pretty sure he means a circular face, like the end of a cylinder. Dave Scott! | 03-27-2018 01:43 PM | Link to comment Share on other sites More sharing options...

[ZE...] Posted March 27, 2018 Author Share Posted March 27, 2018 Abdullah Alghnaim , don't take anything said on this metrology forum personal. Most of these guy's spend their day's walking on pins and needles and are easily disturbed....lol That said, I have heard flatness of a circumference used in the waffer industry.
