    Milling Torque

    Does anyone have a formula for calculating torque required for a milling operation? I have some Inconel to machine and so it will be at very low rpm, I want to know how much torque I will need and so, which machine to put it on.

    ISO steel standard

    EN is a British designation. I found info on EN steels by searching on UK based search engines. Use google.co.uk, yahoo.co.uk etc., instead of .com

    EN30B equivalent

    Thanks for all the info. I have to put a big drill through this stuff. I think 4340 is the closest AISI designation but it does have a higher Cr and Ni content than that. Thanks again.
