Any one ever cut this stuff?

It's killing me.  I need turning and milling ideas.

PCD and Ceramics would be my 1st choice. Looks like some nasty stuff with that nickel, cobalt and chromium. Better you than me. :scooter:

[jlw™]

Yeah, fuh real doe. Look at the very first suggested application. Armor. Freakin Armor.

I remember that stuff from my bicycle building days. In order to fit the tubes together, we had to use a grinding wheel whereas with anything else, even Ti3Al/2.5V, you could use a hole saw. Nasty stuff to work with. Other people were able to make frames with it but we felt it wasn't worth the effort.

AerMet 100 alloy is somewhat more difficult to machine than 4340 at Rockwell C 38. Carbide tools are recommended at 280 to 350 SFM.

 

^^makes it sound easy^^

 

annealing only gets you down to 40Rc. how hard is it without anneal? Judging by the ultimate tensile strength that would be well over 50 Rc.

 

guessing high feed wherever possible.

[jlw™]

No!!!  It hates hi feed cutters.

Has a Kennametal rep been by there today by any chance?

[jlw™]

Nope, two of them.

[jlw™]

Are you at Brown?

One of my friends (Kennametal rep) was tooling up someone on the same material, and the were running Mazak.  Just thought it might have been you.

We cut a bunch of this stuff about 15 years ago.  We started with the material annealed and roughed it.  It machined a lot easier that way.   We finished after heat treat.  It was so long ago that I doubt that I could even find the part files.  We were using Cimatron IT back then.  If I have time i'll look in the morning.

Yeah, him and Lefty were here today.  I needed some help.  Turns out Cartech heat treated it instead of annealing.  We're putting it in the furnace tonight for annealing.  We'll see after that.
