This is a CNC turning application. I'm getting really frustrated with this material. 304 Stainless is probably the worst material I've ever had to machine. I mean even Titanium machines MUCH better. All I want to do is Single Point ID thread a 1/2"-18 thread into a part, but man I've tried 900rpm, 1300rpm, 1700rpm, 2000rpm, 2500rpm and not only do none of them sound particularly nice, I'm getting chipped inserts every 15 to 20 pieces or so and the thread is never consistent. I'm flooding coolant and using carbide 60 degree inserts. Clamp pressure is fine and all other ops on the part cut like butter now. Please, somebody give me a recommendation before I throw this bar stock thru a wall.
