Sorry for the double post, the title I revised to hopefully garner more answers.
I have an Aermet 100 maching question for the forum.
Due to a fatigue issue we are trying to avoid, we have made some parts from Aermet 100, and in the critical areas we have left .015" of stock to be machined off after heat treatment. This is so we can remove the de-carburised layer and obtain the best possible fatigue life in the critical areas.
We will be heattreating be Rc 53-54 (285'000psi)
In peoples experience what type of tool (I assume some grade of carbide) and associated speeds and feeds were used to machine Aermet in the heattreated condition? (I also assume that I'm not going to get very good tool life)
Thanks in advance for any advice
