    A smaller ball interpolated exposes more of the surface to a faster moving cutter leading to a better finish. But the smaller cutter can flex more. Hence the need to balance these two factors. If you have a 4th axis or 5-axis mill you can try "Sturz" milling to combat the slow moving tip. See below for details.
