Depends on the bit and material but I would say you can increase depth of cut per pass to 0.125 and shoot for 150 to 200 safely from my experience. I often am 300 ipm roughing but that is often allowed down by curves

My question is the roughing feed and speed for 1/4 end milll. I know what for for the bowl bit but was wondering if the 1/4 end mill will be the same.

Feed per tooth (IPT), ×, Number of teeth, = Cutting feed (IPR) ; Cutting speed (SFM) × 12, ÷, Tool diameter (in) × π, = Spindle speed (RPM).

I’ve done 0.2 DOC at 100ipm with a similar bit before, but only using adaptive clearing with Fusion. That keeps a constant load on the tool. I’d say 0.25 at 140 is a lot for the router and machine, but should be doable.

I’ve tried .25” depth of pass and things rattle and gets very sketchy that is why I reduced it to .08 with a .375 step over and 100 ipm. This was perfect Bc it was fast and I just did a cleaning pass at the end.
