Hey all,
I have had a question for a few years regarding parts that get turned. If this is this is the incorrect place to ask this on the forum, please move according and I apologize.
As an example part, lets keep it easy. A 10" long cylinder with 3 different diameters along it. One being 2", next being 3", and the last 3.5" in diameter. The lengths of those sections are arbitrary. If the tolerance on those diameters is +/-.005 without using further tolerance like GD&T, what guarantees on a print that they are made about the same axis? I know I can use GD&T to make one of those a reference and do total run-out on the other two surfaces, but without doing that, whats to say one of those diameters is machined on one axis, and the next on an axis .5" offset (exaggerate).
Thanks all!
