[Ro...] Posted October 28, 2023 Share Posted October 28, 2023 Does anyone know how I can check this profile call out on datum A in 7.4? I have another part for this assembly that has the same tolerance for flatness and profile. I imagine the profile call out would be redundant.Screenshot 1.png Link to comment https://qualityforum.zeiss.com/topic/6882-flatness-and-profile-callout-on-datum-surface/ Share on other sites More sharing options...
[Ri...] Posted October 31, 2023 Share Posted October 31, 2023 It appears you have two separate surfaces for Datum A. Those two surfaces must be within 0.008 profile of each other. Your Flatness is separate from the profile and is checked from both surfaces as one.

I've tried profile but doesn't seem to be correct. Or I'm not using it right.

[Ri...] Posted November 2, 2023 Share Posted November 2, 2023 Create the two surfaces, use one surface as your feature and the other as your Primary, secondary and tertiary with the tolerance applied.

Sorry to hijack, but I'm only curious - are this small tolerance values imaginary or do you actually try to do a product on the drawing?

Linear guide carriages. There's a smaller one and larger one in this assembly with similar tolerances.

[Ke...] Posted November 3, 2023 Share Posted November 3, 2023 Seems like a tight Profile callout, given the Flatness tolerance... is this an ISO print?

Missing initial zero for MM is very misleading 🤬 Link to comment https://qualityforum.zeiss.com/topic/6882-flatness-and-profile-callout-on-datum-surface/#findComment-28102 Share on other sites More sharing options...
