Is it acceptable to tolerance the same diameter feature with two tolerances?
I'm being asked to attempt to tolerance the right side of a cylindrical dia. with a +- tolerance of .003 and the left half of the cylindrical feature with a tolerance of -.002 smaller than the right diameter measures.
The reason I was given was based on manufacturing processes & part functional needs where a lathe tool is known to cut from center of the cylindrical length in both directions BUT the part if it has a seam from the tool must be equal to or smaller on the left half as compared to the right.
