Wall Thickness Variation - GD&T
Hello Everyone,
This is my first post, so I figured I'd ask something that has plagued me for years! I'm wondering if anyone knows of a way to properly tolerance wall thickness variation of a tube/ring? Essentially the variation of the section thickness between the Bore and the OD around the entire ring. We typically basterdize runnout and pull the datum to the side of the Bore or OD to represent the "surface". We're not satisfied that this is the most appropriate way to datum this tolerance. It is odd to think of a moving datum but that is what we have. Each radial point of the Bore or OD is the datum for the other. Any ideas would be greatly appreciated!
