By that I mean we have a huge chunk of bronze(3,500lbs.) and our customer wants us to make chips out of it; that's it. Our customer melts the bronze down and their furnace lost power the other day. They were left with this big blob of bronze and they need it machined into shavings so they can start back melting it. Anyway, we're currently using a 6" face mill with positive geometry, .100" depth of cut at 48" IPM. We're just running a simple loop program that spirals in and then down again; rinse and repeat. The piece is in a Mori Seiki MV65 with 25hp at the spindle and a maximum spindle speed of 6,000. Any suggestions with another type cutter? I was thinking maybe something like a 2" milling cutter with radius inserts? Or maybe a 10" face mill? Though I'm not sure about the spindle load with that size cutter.
