Dynamic Profile of a Surface of Revolution

[[Ch...]]

Has anyone programmed a dynamic profile from ASME 14.5 2018?   How do you program the bottom refinement portion which contains the dynamic profile? 

For example, I have a hex nut where I want the hex OD to be very concentric to the threaded ID.  The size isn't that important, but orientation is.

This is where I'm having a brain fart.  How can I tell Calypso to allow my tolerance to zone to expand or contract based on the size of the feature?

"This tolerance
zone may expand or contract while controlling the form,
orientation, and location of the feature within the 0.15
tolerance zone, allowing the size of the feature to
uniformly progress. The actual feature shall simultaneously be within both tolerance zones."

Theoretically you can calculate an diameter and based on it's dimension you can set profile tolerance offset.

Unless ZEISS will make this option inside Calypso.

This isn't a bad idea.  I will have to play with this.

Zeiss should make this an option in Calypso.  Dynamic profile was released in ASME 14.5 2018.  So its fairly new.  But I see a lot more designers getting interested in using dynamic profiles and I suspect we'll all be seeing this more often.  Get ready folks.

I haven't been able to test this, but I was thinking that dynamic profile should be the difference between MAX and MIN from Profile bilateral two results.

Somewhat, in the example shown its a refinement, the total deviation is allowed to be .015, but allowed to float within the .025 total band.  

 

In some other case dynamic profile will affect the shape of the tolerance zone, might be held narrower at the ends and allowed to be larger in the middle portion.  I haven't done much with Dynamic Profile in Calypso, but will look into it.  Possible that the function isn't currently available in Calypso 2025, but I'm not sure as i haven't checked.
