Burunduk, I agree, I have definitely switched my focus to how surface profile should be measured and reported. Could you tell me what book this page came from? Thanks again for all the help!

Pmarc, Absolutely. This is great information, I will continue to review the Y14.45 draft. Thank you very much!

Thank you Burunduk for the clarification, this helps a lot. All my best, S

Chez, Thanks again for the help, I really appreciate it. I can only hope that these things are enough to convince them. Burunduk, I think maybe you're focusing too much on the rough sketch example I drew up for this. While I believe I understand what you're saying, I don't see why there is...

Burunduk, In the actual print, the bore is the primary datum feature, the secondary is actually not shown in my example, and the third datum feature is the plane at the top. Using these 3 features for our reference frame and the solid model on a CMM we can measure the surface profile of the...

The sketch was indeed only intended to show the deviation i was talking about, it is not representative of the actual drawing or its datum features, just an example of how they interact, Datum A is a hole and datum B in this case is a planar surface.

Thanks very much for the reassurance! Yes, I operate using ASME Y14.5, my apologies for forgetting to specify.

Hi Burunduk, Here is a quick example, the left shows a zoomed out version of the datum configuration and feature to be controlled. On the right of the image is a blown up example of how the feature sits within the tolerance window and how it affects the linear dimension reading. All...

Hi all, first timer here. I'm dealing with a customer who wants to reject a part based off the linear measurement of a basic dimension while the surface profile of the feature is within specification. The feature is a planar surface that is being measured to a point constructed from the...
