I am wondering how best to dimension a part with the following characteristics. It is shaped like a short shaft with a bore down its length and a series of rectangular keyways cut full length into it. The keyways are equally spaced, so it is essentially a splined shaft with rectangular grooves. I want to separately control the distance from the keyway bottoms to the axis of the bore and the variation of that same distance; I want to have a tighter tolerance on the variation of the dimension than on the dimension itself. It would be akin to the runout tolerance except it's not a cylindrical form. How can I do this?
