Why is the table saw blade burning oak boards as I make rip cuts

sawtable-saw

Bought a new saw blade, most expensive one I've seen and it still burns the wood and takes some pushing to get through.
I am ripping 1 3/4 thick oak with the grain.
Blade is Orange Chrome Heavy Duty Multi Purpose Carbide 10" x 0.126"
60 TCG

Am I expecting too much? Wrong type of blade? Bad blade?

High tooth count will give smooth results in most cases, but they can heat up in hard wood. More teeth leads to more friction. It's probably a fine all purpose blade, but ripping a hardwood like oak, especially very thick boards, is probably a reason to use a dedicated ripping blade.

Ripping blades have 24-30 teeth, and the tooth profile is flat on top. Some may have a slightly thicker kerf to avoid binding if the board twists or pinches when it's cut. Each tooth takes a bigger bite, but when you're going with the grain, you can afford to do that. Fewer teeth means less friction and heat.

Wood – use an 8“ dado blade set in a 10” table saw

There is NO problem with using an 8 inch dado blade on a 10 inch saw. In fact, it is quite common to do so. I use an 8 inch stack on my Delta contractor's saw with no problems, and before that, I used an 8 inch wobble dado.

You certainly would not want to use a 12 inch blade on a 10 inch saw, as that large of a blade might have clearance problems as it is adjusted. Use of a larger blade also causes somewhat larger tip speeds, so that might potentially cause problems. (Unlikely, but possible, since the differential in tip speed would be only 20%.) Perhaps these issues are what the author meant when they made that statement.

In going to a smaller blade diameter though, the only question is whether that blade will be able to reach the surface of your table. On an 8 inch blade there is no problem.

Wood – What’s the best way to account for saw blade width (kerf) when cutting boards

Yes, you might want the highest precision possible - for example when you build furniture which benefits greatly from precise cuts. The most convenient way would be to draw the line that will signify the edge of the piece you want cut so that the blade cuts the line and whatever material is on the far side of the raw board. Something like this:

 |the detail you want|line|remaining material|
 |                   |blade cuts here|

This is quite easily achieved with power saws even without a guide and will be more of a challenge with hand saws.
