Is there a Standard for deburring or removing material? The only one I'm familiar with is BAC5300 and that's boeing drawings.
#1) The problem I currently have: The drawing will say something like "Edge break and Deburr .015 Max Unless otherwise specified", and the guys use up their full allowance and end up creating a knifes edge on a tube because they knocked out the flat in the process. We had something recently where a tube had about .012 of wall left on each end with a burr, so the guys went in and knocked the burr out along with the flat at each end creating a knife edge in the process. Nothing on the drawing prevents them from doing this since all features are still in tolerance. BAC has 20% rule to prevent this but I can't make them use a boeing standard on a non-boeing drawing.
#2) Kinda same problem: Using all their tolerance to the point of removing a feature completely.
The drawing will ay something like ".xx = plus or minus .03" and a drawing might have a feature like radius .015, so it never fails I will get a guy who will run the feature without a radius then tell me "drawing says plus or minus .03". Once again BAC5300 prevents this nonsense but not with certain customers drawings and procedures. I haven't been able to find anything relating to this in any of the ASME y14.5 tolerancing...
Any help is appreciated, Thank You.
