[To...] Posted March 16, 2020 Share Posted March 16, 2020 I have this part were I am currently doing a formula to give me the tolerance, but I guess there should be someway to avoid this. How can I construct this and let Calypso do the calculation for tolerance? I have tried different things, but I guess I haven' tried the right one yet.

[Te...] Posted March 16, 2020 Share Posted March 16, 2020 You can create a theoretical circle using formula to fill in the info you want (X,Y,Z, DIA) and then report position to that circle which will allow for MMC Link to comment https://qualityforum.zeiss.com/topic/16212-symmetri-of-slot/#findComment-89946 Share on other sites More sharing options...

Theoretical circle should work just as well, make sure ID/OD is specified correctly for MMC. Good luck and happy measuring.

This could maybe be an option, but the two slots has to be evaluated as CT, so it should actually be a cylinder combining the two slots.

What I am doing now is; Scanning two lines in the depths of 0,8.

[Ch...] Posted March 17, 2020 Share Posted March 17, 2020 What are the features in the slot, it appears to be planes/surfaces at 80°, if these continue past the 0,8 basic here's what I might recommend: measure each 80° plane. Create /construct a 0.8 theoretical or offset plane from the surface shown. Intersect this with each of the (2) 80° planes. This should give you an "x" value position or whatever axis these features lie in. Construct a theoretical plane using these "x" values. Construct symmetry plane from these 2 planes. Calypso should allow for MMC. Watch the direction of the planes, make sure they correspond with MMC, not LMC. There are other ways to do this. Create a theo circle based on x1+x2 dist value. Possibly fitting circle in contour as well, which might be the most challenging. Good luck. happy measuring! and happy st pattys day ! 🤠 Link to comment https://qualityforum.zeiss.com/topic/16212-symmetri-of-slot/#findComment-89954 Share on other sites More sharing options...
