GD&T ???

[Rob @ Target Machine]

I haven't seen this before. I know it's a profile of a surface w/in .004, but the rest is a little over the top. The AB-BA notations are arc endpoints and intersections. This is not in my GD&T book. ie. ASME Y14.5M-1994.

 

 

 

Any idea what they are looking for?

I've never seen this before too.

Yup,

 

There are datum points on the print and those are points between which the tolerance applies.

 

I did a bunch of this stuff a couple of years ago

 

Lockheed Martin, I'm bettin'

Yeah I know this software that would allow you to collect those points and then do an analysis of those points back to the surface model and give them a screen shot showing the deviations at each point to what ever tolerance you want as well as give them a complete detail report showing all of that is a matter of minutes.

 

Email me if you need some help giving source something back.

JP - You're right Lockheed Martin.

 

I was guessing that these AA-BB callouts were line or arc segments that are referred to by the feature control frame.

 

I usually see the all around symbol with this F.C. frame.

 

Ron - We don't have a CMM. I wish we did. Then we could write PC DMIS proggies to do the work for us. I'm still working on getting a new inspector right now. Ours just retired. Maybe we can justify the purchase if we hire someone with pcdmis experience.

 

Thanks guys.
