In this paper, we present a first attempt to define the basic geometry, mechanics, and physics of the process of mechanical alloying. The geometry of the collision events which lead to particle fragmentation and coalescence is modeled on the basis of Hertzian contacts between the grinding media which entrap a certain amount of material volume between the impacting surfaces. This …

Another way to approach this with a manual milling machine would be to use a ball end, end mill. Calculate the in-feed (down feed on the mill) at intervals and make multiple passes across the width of the aluminum. An end mill with a 1/2" ball radius and intervals of 1/4" should get it fine enough for a file to take out the waves in the cut.
