I have been building some kitchen cabinets of late. I have a 10"
Delta Unisaw and I've never had burning with a combination blade. I
purchased a 80 tooth Oldham Industrial Carbide finishing blade for
this project. I also built a large crosscut sled. As usual, I set my
blade depth so that 3 - 4 teeth are protruding through the top of the
material being cut.

Problem. Cutting through 3/4 inch melamin-surfaced particle board
there is a little bit of burning evident on the material. When I
start using the crosscut sled, the burning is *very* noticable. After
cutting a batch of panels the air is very acrid and smokey.

The blade is square to the fence. The blade is sharp. The blade is
clean. I've experimented with faster/ slower feed rates, with not
much success. The sled is true and produces very lovely, perfectly
square panels -- just nicely toasted on the edges.

Any ideas?
