Guys,

Just wanted to see what you guys are running for your speeds, feeds and depth of cut for Hard Nickle based material? Such as Inconel.

Right now for a 1.0" Carbide Endmill we are using .649 Feed and a RPM of 324 with a depth of cut of .050. I think this is wayyyyy to conservitive but was wanting a baseline to back up what I am thinking.

Thanks

Finishing 80 sfm
Slotting 40 sfm max
1/2 diameter for depth

These are for 718 Inconel. 800 series you can increase upwards to 180sfm or so.

As stated above 1/2 diameter as a rule and .002-.004 fpt on a 1". Work upwards from there.
