I've been successfully cutting MDF on a K2 CNC machine, details below: Bit: 1/4" two-flute spiral upcut Speed: 120ipm Depth of cut: 1/4" Rout
I cut 3/4" birch plywood or MDF in a single pass with a 3/8" compression bit, with no problem (400ipm, 14000rpm). But on my old machine I had to cut 1/8" passes with a 1/4" . I’d say 0.25 at 140 is a lot for the router and machine, but should be doable. Using a 1/4" flat endmill, 2 flutes, you can safely rough at 0.125 DOC and 100ipm. I’ve recently done 0.25 DOC at 80ipm without a problem. I created a Free CNC calculator to help sort a delicate balance between Feed Rates, Chip Loads, Spindle Speed, and Power that go into finding a CNC setup the optimizes finish quality and minimizes the time required.
If you are rough cutting 3/4 MDF or flake, I use a 1/2" Onsrud 60-053 at 14,500RPM and 1100 IPM. This is a slow helix hogging bit with a corrugated edge. Not so good for veneers or paint, .I've been running them at 18K RPM, 50 IPM full depth (up to 3/4" on my machine) and one pass. They don't scream like the larger cutters can, and they cut like a laser. No tabs needed as the .
MDF is a widely-used material in many building projects and household products. Here's our starter guide to cutting MDF with a CNC machine. A ¼” (6mm) will cut through 12mm in one pass but as long as your cutting-edge length is long enough you can cut 18mm with two passes, first pass of 12mm, 2nd pass of 6mm or two passes of 9mm each; Solid carbide tools .
But. assuming vacuum hold down and fairly good sized parts, you should be able to clean cuts on top and bottom if you use a 1/4" mortise compression @ 13,500 rpm around 300 ipm (.011 chipload) with no problem. You should adjust the feed down to lower chipload to accommodate your machine. Will the two straight flutes cut faster than the spiral end mill flutes? These questions are more for cutting one pass through 3/4 MDF. Is that even recommended, or should I take 2 -4 passes?

Not so good for veneers or paint, but for templates, diewall ribs, general parts, etc. it works great. I've been running them at 18K RPM, 50 IPM full depth (up to 3/4" on my machine) and one pass.
