    Default roughing question

    Hey Guys
    I have a bunch of aluminum motorcycle trees I need to make on my mill. I have a Acurite 3500i control on it and I'm trying to rough in out in a timely matter. I'm looking for ides that will help me decrease the time it takes for roughing without knocking my mill head all out of wack.
    Thanks for any input
    Mike

    Aluminum cutting roughing end mills. Probably in the 1/2 or 5/8 diameter, use the manufactures recommended feed and speed. You should be able to cut full depth at a reasonable feed rate. Build a fixture that supports the part a couple inches off of the table, and provide chip clearance. This lets the chips just fall out under the part.
