Trying to surface mdf board.
For large (relatively) fly cutters, you want low DOC, low RPMs and high feed rates.
I have a 1" 4 cutter, I run 10K RPM and start at 100 IPM feed. I usually up the feedrate in CM to 150% or even higher. Once you have a comfortable feedrate, you can experiment with deeper DOC.

There’s also F&S values available on that page, but it’s not clear what size machine they are for. Their Document says for MDF, 200 IPM @ 17K RPM.
