I'm in a ornery mood, and I'm stuck at the shop cuz the roads are closed, so I'm going to bitch, constructively.
29/64, .450ish. 675 RPM's. Thats about 80sfm.
The bitching part. I had to calculate that. Why did I have to calculate that? Hmmm Cheenist? Its because you didn't. And you want to know why you are roasting a drill? Its because you didn't calculate it.
Just a pet peeve.
I'm not a Ti expert, but I did a shit load of it a month or so ago. I'd say its easier than 304. I'd say you need to knock down the SFM. 30 on the conservative side, maybe to 50ish.
Was this a chisel point? I wouldn't do that, if you have to, pilot with a 3/16 or so.
Feed seems heavy. Ti seems like it takes a lot of force to cut. I was running U drills, and then reaming with a .380 reamer, 2" deep, I was running conservative, really conservative while keeping a respective feed. and the drill was walking all over the place(split point cobalts). Went to a bit smaller drill, straighten with a 3/8 endmill, and then ream. Hole size was a mess. The damn reamer was bending. Chopped the reamer down, and everything was fine.
Back it down, get some good drills and you should be fine. The 6Al4V really does cut easy. Just don't beat on it.
