Utterly confused by this print, I'm guessing they want a runout of 0.008 between the major of the spline and the stock shaft OD but is this called out correctly? Thanks
The runout to itself does not make any sense. For the spline, datum A is not the OD, but the axis of the Ø1.496-1.500, but I would also interpret this as the runout of the spline Major Diameter relative to the axis of cylinder Datum A since it is attached to the Major. If it were attached to the spline callout, I would ask the customer what they want
I would say it's the runout of the spline pitch diameter to Datum A. If they are turning a blank and then creating the splines from the blank, then if you check the spline Major diameter you are checking the turning to itself, if that makes sense.
That is a wacky callout. First of all, the diameter is a Reference feature. But they decided to put a circular runout callout on it - relative to itself?
If it were a total runout callout, I would interpret it as they want the cylindricity, but they have something 'special' there.
The rightmost runout is using the datum triangle to connect to the feature, is that datum A then?
The leftmost runout has the datum not connected to the centerline, meaning that datum A is the surface (generatrix).
I'd say you need clarification from the designer and a revised drawing.
