Hi,
I have a few parts to make with deep side walls without step down lines. I have mainly been using 3/4 3 flute ZrN carbide endmills in side locks, and I also have a 1x3" 3 flute ZrN finisher which is now chipped mid-flute. I bought a huge HSS endmill with 6 flutes, it has a 1-1/4 shank diameter with flats and a 1.5" cutting diameter with a 6" LOC. I'll be holding it in a Maritool 1-1/4 dual contact sidelock in a CAT40 VMC. Total gauge length with be around 8.5 inches I think.
What range of cutting speeds, feeds, WOCs and DOCs should I be looking at for a tool like this? Some of my parts have 3, 4, and 6 inch side walls that I want flat and square. If I can get these side walls done in the first operation, I can use them as reference surfaces to hold them in the vises for the remaining operations on other sides. If they aren't square they may not be stable to hold in the vises, and I don't want a part to move in the vise jaws when I'm taking heavy cuts.
