[Ma...] Posted November 23, 2023 Share Posted November 23, 2023 Calypso uses some hidden formulas to get that, but it depends on used evaluation method. I wonder how you on ASME are handling circles/cylinders/cones on less than 180°deg Link to comment https://qualityforum.zeiss.com/topic/6788-evaluate-diameter-full-360-degree-circle-and-180-degree-semicircle/#findComment-27504 Share on other sites More sharing options...
[K...] Posted November 23, 2023 Author Share Posted November 23, 2023 Thank you Martin: May I know how to report UF x2 Ø67 callout, and how to handling less than 180°deg.

[Ma...] Posted November 23, 2023 Share Posted November 23, 2023 Please sign in to view this quote. By UF you mean United Feature? I would recall points into one feature. For ISO is used Gauss - so no problem with calculation, but for ASME - IT/OT can not be done on less than 180° I am the one who asks ASME people how they do it 🙂 Link to comment https://qualityforum.zeiss.com/topic/6788-evaluate-diameter-full-360-degree-circle-and-180-degree-semicircle/#findComment-27508 Share on other sites More sharing options...
[K...] Posted November 23, 2023 Author Share Posted November 23, 2023 I measured diameter of Can (UF x2 Ø67mm) from a center reference using two semicircles (10° ~ 170° , & 190° ~ 350° ) due to grooves but reported 3 different diameters: • 1st based on full circle (both semicircle), • 2nd based on top semicircle ( 10° ~ 170° ) • 3rd based on bottom semicircle ( 190° ~ 350° ). I noted that the full circle diameter was smaller (approx: 0.200mm) than both semicircles. I also noticed both semicircle centers are out from the center (concentricity higher than full circle). What is best way to report (UF x2 Ø67mm) callout.

[Ma...] Posted November 23, 2023 Share Posted November 23, 2023 If it's UF, then you should report one measurement of complete circle using both semi-circles - Without UF you would have two separate circles divided by groove/s Link to comment https://qualityforum.zeiss.com/topic/6788-evaluate-diameter-full-360-degree-circle-and-180-degree-semicircle/#findComment-27512 Share on other sites More sharing options...

[K...] Posted November 23, 2023 Author Share Posted November 23, 2023 But it is UF x2 (what is x2 means) Link to comment https://qualityforum.zeiss.com/topic/6788-evaluate-diameter-full-360-degree-circle-and-180-degree-semicircle/#findComment-27516 Share on other sites More sharing options...
[Ma...] Posted November 23, 2023 Share Posted November 23, 2023 I am not sure - haven't seen a drawing nor a part, so my guess is limited.
