Metal Removal

Yeah, it's got some grunt!

I'd be happy to get together with you and show you how I'm attacking it if would help you out, G.   Shoot me an email @ [email protected].

The tool is 5544403 w/ 6019506 Inserts.   Running it at 62.5 IPM @ 1786 RPM (.007 FPT @ 935 SFM).   With a .4" Stepover, and, as mentioned, starting at a .3 DOC at the top, it generally has a bit less than 45% spindle load.

That Okuma is a powerful machine!
I mostly use Ingersoll 1/2" button cutters and mid feed face mills for roughing

Have you looked at the Sandvik 745 cutters? 14 cutting edges per insert and they are beefy inserts.

Gcode is this you running this big ass machine wearing a bicycle helmet?

I'm working on a part that made me think of you, G.   I'm starting with an (already turned) blank of A36 that's #3216, and after the first roughing op it's #1908.  This is half of a rotor that'll be pinned together to be finished and then bolted to a diaphragm wall. 

I managed to get 'em down to a bit less than 9 hours to do that, so 1308/11 = 118 lb/hr.

That'll do pig.
