[SH...] Posted November 6, 2021 Share Posted November 6, 2021 I have a drawing in which it is mentioned as ANSI and DIN for true position. How do I check this?. Do I have to change the evaluation??IMG_20211106_225209.jpg Link to comment Share on other sites More sharing options...
[Ma...] Posted November 6, 2021 Share Posted November 6, 2021 Seems like norms for screws. All i found was ANSI as UNC / UNF threads - DIN is basicaly ISO Link to comment Share on other sites More sharing options...
[Br...] Posted November 8, 2021 Share Posted November 8, 2021 That is just weird. I guess they mean they want it to meet both ASME Y14.5(previously ANSI Y14.5) and DIN EN ISO 1101(GPS) standards for position. The only difference that I know of for your application would be the "Axis" being evaluated and the definition of an axis for both. ASME states that the axis of the cylindrical feature is perfectly straight (no form error) and it is produced by the actual mating envelope of the feature. ISO defines an axis as more of a derived median line that is produced by all the crossections of the cylindrical feature. There may be some differences regarding the MMB and MMC modifiers as well but I am not as well versed in ISO GPS. Link to comment Share on other sites More sharing options...
