It all depends on your machine really. What I would do is experament with it some. Take some scrap material and start at .050 deep then sideload. If it has no trouble, then go .100 deep. But I would keep it at about .100 that is what I have used on the bridgeport machines and its happy. Now on my little mill, with the 1/5 hp motor I could only go .025 to .035, so its all in the motor. Stay around .100 and you should be fine. For smaller dia. endmills you want a fester RPM, larger endmills you want slower. There is a mathamatical equasion to cutting speeds, but I dont have it in front of me at the moment.

That should help ya I think. Remember to use coolant of some sort, WD 40 is great for aluminum. And WEAR EYE PROTECTION always.

Have fun
