I'm not the expert that Ed is, either, but what I do is slightly different that what Ken suggests after reading the book, Knife Engineering by Dr Larrin Thomas.
He says that for simple steels like 1084, successively lower temps during the 3 thermal cycling steps isn't necessary, and the 1st at 1500F isn't really a grain reduction temp (IIRC).
When I'm finished forging, I normalize at about 1700F, then do 3 grain reduction cycles at 1350F.
Do you need to do this when doing stock removal? That depends on where you get your steel from. I'd call the vendor and ask them if this has been done or not.
