· So I know this topic comes up a lot but I'm still confused. My question regards cutting feeds and speeds in 6061 and 7075 aluminum. the majority of our machining is done on a Haas Mini Mill. During roughing i have an rpm of 2400 and a feerate of 11 (guessing its inches per minute). Now that gives me a chip load of 0.0011.

Keep a low cut width (or cut depth if you’re talking the floor of a pocket or surfacing with a Face Mill) and do a separate finish pass. The depth of cut has to be larger than the chip load, or you can get rubbing. Usually something like 2-3x chip load will be right for the finish pass. I do a lot of finish passes in the 0.015″ neighborhood.

Mill Finish rails are generally less expensive due to them not undergoing extra surface treatment as clear anodized rails. Mill finish rails are shinier in appearance due to this and are more easily scratched. Due to the bare aluminum being exposed to the weather elements, overtime the rail will oxidize.

Aluminum can melt and fuse to the tool if there’s too much heat. So even though it cuts like butter, it won’t for long if the aluminum sticks to the tool and you end up doing friction stir welding instead of machining.
