An ellipse can be exploded directly into arcs, whether you get all arcs, all lines, or arcs and lines, depends on the size of the ellipse and the explode tolerance. A spline needs to be exploded into a polyline then the polyline can be run through the PolyarcFit on the Curves menu to create arcs, again, it all depends on the shape of the polyline and the tolerance you give it as to whether you will get all arcs, all lines, or arcs and lines.
BTW, I've machined splines quite successfully for a number of years, it all depends on a number of variables, like tolerance and surface finish, to name 2.

A spline ain't worth crap (as far as machining). Same goes for an ellipse.
