Milling Aluminum

I have access to a CNC mill at a University, but have not found anyone who really knows much about machining or selecting tools for it.

I would like to mill a series of triangles into 2024-T3 aluminum, 1/4 inch thick. Cut all the way through.

What cutting tool do I buy to make cuts like this. I would guess something like a 1/4" diameter, double ended 4 flute mill. Is there any rule of thumb or common sizes that tend to be more economical, or work better?

The diameter of the mill will affect inside radius at the corners, of course. A larger mill cutter might be stronger, but would have to remove more material. A smaller cutter would remove less material, but at some point becomes fragile.

And of course, there are differnt coatings on the cutters. What would be an appropriate cutter for aluminum?

Finally, what type of surface speed should you start with?

Regards-
Norm
