    Default Is it possible to get a good finish with a 12t 3" shell mill?

    Before I make a mountain of scrap has anyone found a recipe for a 3"HSS general use shell mill on Aluminum?

    I plugged it in my calc app which gave me 1222rpm and 80ipm which resulted in a less than mirror finish.

    I am using my DM3220 VMC with a Showa toolholder and niagra cutter.
