I have a machining operation with uses a 1 inch/25mm tool that is 8 inches/200mm long in my vertical machining center. In addition, the part geometry is relatively weak as this is the 3rd op on an aerospace-type structure with a very large amount of material removal. Due to vibration in the part and tooling, I am taking just a .040/1mm radial depth and a .4/10 axial depth of cut. Any more and the vibration gets out of control. The part geometry means I cannot use a larger diameter or shorter tool. A few years ago I bought a high feed mill that is the same dimension due to making a mistake writing down the part numbers....
Last week I loaded up the Highfeel endmill tool for a quick prototype when all my other tools were tied up to circular interpolate a deep small hole in aluminum. Since it was just a few parts I went really conservative (suggested steel speeds and feeds) but it sounded great in the cut and the chips with easy to evacuate for this small deep hole. I am considering trying this for my long 3rd operation on the structure part. Any thoughts or experience using high feed mills in 6061-T6 to aid an unstable setup?
