There can be alot of feed lines involved if you straight up hand program it or you use a CAM system as I do. The other alternative would be using a canned cycle which cuts out most of the feed lines, all you have to do is define the profile of you finished surface and the control calculates the tool pathes. The downside to that is, if there is something wrong, it can be a bit more of a boat bang to diagnose. The last dome program that I ran, i think I had the spindle up around 4500 rpm and 0.4mmpr.
Old skool is cool, but there aren't that many hand made parts going on F1 cars, unless you count the hand laid composites. :baseball_santa:
