I am cutting some alumalite with is 6mm thick. It is a composite thin aluminum on both sides with a plastic core. It routes very easy with a hand router and a straight bit on a table. but when I try it on a cnc and use a down fluted bit it doesn't always come out good and smooth. I cut circles out and in a sheet 2x4 screwed down I get 80% come out okay but the other 20 have a rough edge one side of the sheet. on the picture you can see the bottom. I sanded the plastic out of the way.. also the plastic gets torn up pretty good with the fluted bits. when I used a straight bit on hand router the plastic did not curl up like this. any one have any experence with cutting this material?
