Anyone know how to turn titanium? Answered

I've found a few instructables here for making titanium rings which have been great. 

The only problem is, I have no idea of the feeds/speeds, especially when boring the interior of the ring.

I successfully was able to find the right speed and feed today for cutting the exterior, and was able to cut a piece off the bar stock. 

If anyone knows anything that would help, it would be much appreciated. 

Thank you
