Not being funny here but you can't ask questions about feeds n speeds and expect any sensible reply if you don't give all the details. You say 4 and 6mm but no mention of # flutes. Then you still have the machine to factor into the mix.? Is this a router with 2.2Kw spindle.? or is it a mill.? These make a big difference to how you would tackle this job and esp this material.! . . For instance, I wouldn't even attempt to try to cut Stainless with a router unless it was built like a brick shit house.!
