The first thing you'll notice when doing this kind of cut is that if your stock is not flat, and does not ride flush against the table saw fence, the blade will tend to burn inside the cut. This is because the wood is being turned slightly against the side of the blade during the cut. You want to minimize this kind of action because it is bad for the blade to heat it this way, it is bad for the wood to burn it, but mostly because if this action is severe enough the blade can bind or worse.
