Like has been said, feed rate is to slow. Think about using a router table or hand router. If you move the router/material to slow, the bit will burn the wood. Same principle on the CNC. Same principle on the tablesaw.

Believe it or not, I use a 1/4" compression bit for cutting hard and soft woods. Don't use the mortise compression bit which has a smaller up cut section at the bottom.

I first do a climb cut at about 4ips with 13K rpm leaving a 1/32" skin. Depth per pass is dependent on the wood type. Harder woods like maple, hickory, etc. I use no more than 1/4" per pass. For softwoods I will cut 3/8" per pass. The climb cut will significantly reduce tear out, just like with a router table or hand router. I then do a full thru conventional cut pass. I'll slow my feed rate to about 3.5ips and use the same bit rpm. The beauty of this setup is you can save both toolpaths to one file (if you use the same bit from the tool database) and have it all done without starting a new cut file.

It is important to remember that with a compression bit, you need to plunge down about 3/16" at the start of your first climb pass. The upcut spiral on the bottom of the bit will cause tearout if you do a regular ramp cut into the wood.

Make sure the bit is VERY sharp. I tend to NOT resharpen bits as the bit is not nearly as sharp as a new bit. Just my opinion and about 7 years of trial and terror. LOL......
