[Ca...] Posted February 17, 2022 Share Posted February 17, 2022 I have a part with an OD slot, that has a .000 Perp at MMC. How can I put this in a Perp. Characteristic? I'm struggling with this, and maybe the solution is right in front of me, any suggestions would be appreciated.

[Cl...] Posted February 17, 2022 Share Posted February 17, 2022 If you have curve you could scan the slot and use (assuming this work-piece is in the XY work-plane) max (X+) and min (X-) coordinate. Then construct a line form those two points. This will also give you the length (point to point).

[Ca...] Posted February 17, 2022 Author Share Posted February 17, 2022 I'm sorry, I usually state our software. We do not have Curve/FFS/PCM. Link to comment https://qualityforum.zeiss.com/topic/10990-perp-of-000-at-mmc/#findComment-53540 Share on other sites More sharing options...
[Mi...] Posted February 17, 2022 Share Posted February 17, 2022 I took the question to be more about how to interpret the perpendicularity with MMC callout - and I'm at a loss. But as far as strategies without Curve, I would: - construct a symmetry plane based on the two flats - scan each end as its own "circle" feature - intersect the circles with the symmetry plane - repeat at multiple heights, then recall the intersections into 3d lines at each end Link to comment https://qualityforum.zeiss.com/topic/10990-perp-of-000-at-mmc/#findComment-53542 Share on other sites More sharing options...

[Ma...] Posted February 18, 2022 Share Posted February 18, 2022 Moin, the stragies from Michael is not bad, with the intersect point I would make a recall in a circle "Ø" and there you can evaluate the position with "M" and th diameter. I hope this is intersection 🤣 Link to comment https://qualityforum.zeiss.com/topic/10990-perp-of-000-at-mmc/#findComment-53546 Share on other sites More sharing options...

[SH...] Posted February 18, 2022 Share Posted February 18, 2022 Create 3 slot top middle bottom using, these slot create a 3D line .you can use the 3D line for perpendicular checking ,then add formula in the perpendicular to tolerance column. formula is difference between slot length at MMC and actual slot length.
