[Ke...] Posted December 20, 2021 Share Posted December 20, 2021 I'm looking at a print with a cylindrical feature with a size tolerance of +0.015/-0.005mm. There is also a roundness callout of 0.05mm, for this feature... Working to ASME, at the latest revision.: Doesn't the envelope principle limit the cylindricity of the feature to 0.020mm? (maybe the roundness was intended to be 0.005, instead of 0.05) Link to comment Share on other sites More sharing options...
[Ro...] Posted December 20, 2021 Share Posted December 20, 2021 Hi Keith, You are correct. Sounds like a typo. On the flip side... you're part should easily pass the .05 roundness tolerance. 🤣 Link to comment Share on other sites More sharing options...
