Thank you for your interest! I'm think there is nothing intresting in the Milling Process, of course if you never do it maybe it's interesting for but i'm really doesn't use some trick in this process. I'm preparing my model by the Decimation Master to about 1 million poly, not more then 2 million, then export this with 3d Print Eporter to the stl format. For milling i am using PowerMill but there is without surprize too, just three, i'm don't know how it say, trajectory for cutting. One is for remove the lot of material, one is for take of the rest material, and one is for the good surfaces.
Just the model.
The first trajectory.
The result of calculation the first traectory.
The second trajectory.
The last result of calculation.
