Circularity vs regular +/- dimension
Hey, I have came across the drawing in which certain cylinder had a +/- diemnsion and a circulairty tolerance. Tolerances were +/-.010in and 0.080in for a circularity. It made me wonder, isn't that circularity tolerance redundant?
If this feature is holding to +/- tolerance it certainly holds to circularit tolerance and then the opposite good part in circularity tolerance may be not good enough for +/-.
Is there something that im missing? Does that circularity bring something extra to the definition?
