MDB or 3D PMI requires the Engineer to complete the Model and all tolerancing for all features. Unfortunately this does not always occur for the Model
We do perform inspections on composite material using a GOM Blue Light ATOS 3D Scanner and gave the tolerance based on the Model with a...
Nescius,
Maybe you are not understanding my intend of why I record Basic Dimensions on the FAI. True they are not shown as passing or failing for that line item but the basic dimension actuals support the actual positional. They are absolutely necessary to calculate the position. Your...
I'm glad we are having a very good debate on this subject.
I like what AS9102 says using a CMM and how we must program it for FAI purposes.
When automated inspection tooling produces measurement results, those results may be referenced on 9102 Form 3, identified as pass/fail, and attached...
Nescius,
You are probably not going to like my answer on this because I normally do not take a 2D diameter on a three dimensional surface unless the a small depth of the cylinder precludes otherwise. Per ASME Y14.5-2009 and back to ANSI Y14.5-1973 version, the ø symbol in the Feature Control...
Nescius,
Thank you for your insight. I agree that some things don't need to be on the FAI like implied 90 degree angles, or implied zero distances. those thing are not on the Drawing and therefore are not required. I also agree that What Company waits till the FAI to fix the process and...
Hi Dave,
I have read your initial response and want to point out that the passing an audit is ancillary and a perk to the actual requirement if AS9102 in recording Design Characteristics on a drawing. If an inspector doesn't understand GD&T they should not be a precision part inspector. You...

I have recently had an internal discussion at my company over whether or not to include Basic dimensions in an AS9102 First Article. The answer is yes you do. Pure and simple. To do otherwise is not complying with the AS9201 Standard. Basic Dimensions are part of the...
