Burunduk replied to the thread RMB for width as tertiary.I don't think so. Nothing in (e) either, or prior to that, indicates a simulator for a RMB width datum must initiate contraction or... -

Burunduk replied to the thread RMB for width as tertiary.You mean the jaws should grab datum feature C, not B. That width (datum feature C) has an MMC of 1.005 and a position tolerance of .015...

After giving it some more thought, I take back what I said. The illustration in the book is correct and I was wrong. Sorry for the...

Burunduk replied to the thread RMB for width as tertiary.I think I'm not sure I get it. Is it because datum feature simulator B doesn't constrain rotation? Edit: I don't think datum feature...

Burunduk replied to the thread MMB calculation.[A,B(M)] and [A,B(M),C] yield the same MMB. That MMB is based on the limits of size of datum feature B and its control relative to datum...

Burunduk replied to the thread MMB calculation.The MMB of a datum featute is simply it's worst case for assembly boundary accounting for the controls that apply to that datum feature...
-
Burunduk replied to the thread RMB for width as tertiary.A good educational example should start by telling about the use of the part, how it mounts and works. The selection of datum features...

Burunduk replied to the thread Datum Modifier Effects - Planar Surface.The simple case of a flat on a cylinder being part of an interface and locking rotation, reflected by the RMB example of such geometry...

Burunduk replied to the thread RMB for width as tertiary.The standard requires datum feature simulators for datum features referenced in the same feature control frame to be basically located...

Burunduk replied to the thread Datum Modifier Effects - Planar Surface.Before the 2009 revision, the standard didn’t address this topic at all, meaning there was a lack of guidance on how to handle similar...

Burunduk replied to the thread Datum Modifier Effects - Planar Surface.greenimi, I think that per pmarc's position (which I agree with), in case of a return to the 2009 rules you would still be calling it...
