[Ri...] Posted April 22, 2021 Share Posted April 22, 2021 I don't know if this is an ASME or ISO drawing, but I'm not certain it would matter in this case. Is this even valid?

[Th...] Posted April 22, 2021 Share Posted April 22, 2021 Inasfar as ASME goes, I don't think so. 14.5-2009 8.5 says modifiers are only allowed on the datum features.

[Ri...] Posted April 22, 2021 Author Share Posted April 22, 2021 OK. I mean MMC would mean a feature of size, but on a Profile - what is exactly being determined as the feature of size (especially in this case).

[Da...] Posted April 23, 2021 Share Posted April 23, 2021 Please sign in to view this quote. Same for ISO, if there are any exceptions, please someone chime in. edit: And for both, datum has to be feature of size.

[Ri...] Posted April 23, 2021 Author Share Posted April 23, 2021 Hi Andreas, Unfortunately they didn't put a specification on the square. What you see on my drawing is exactly how it is on the customer's drawing.

[Er...] Posted April 23, 2021 Share Posted April 23, 2021 Richard, Is there any note: stating something like the cad model is the master for all dimensions not shown on the drawing? If not, then this really doesn't make any sense. I have a similar print, with no datums, and a .020 Part profile, unless otherwise stated. We had to bring this up to the customer and ask more questions as to what the intent of this profile was for. They told us they basically want the part to match the model. within .020" Link to comment https://qualityforum.zeiss.com/topic/13052-surface-profile-mmc/#findComment-66138 Share on other sites More sharing options...
[Ri...] Posted April 23, 2021 Author Share Posted April 23, 2021 THE ITEMS DEPICTED SHALL BE MANUFACTURED AND INSPECTED USING BOTH THE COMPUTER AIDED DESIGN (CAD) DIGITAL DATA FILE AND THE DRAWING. UNLESS OTHERWISE SPECIFIED ON THE DRAWING. THE FOLLOWING APPLIES: 5.1 FEATURES IN THE CAD DIGITAL DATA FILE ARE BASIC IN SIZE, FORM, LOCATION AND ORIENTATION.
