I've read that when using a half blind dovetail jig, it is sometimes helpful to "backroute" with a skim pass before you make main cut, though that didn't help much when I used the technique on plywood for some reason?

Also, when using a rabbeting bit, especially on a curved edge where the grain changes direction along the path, making a light skim pass backwards first to remove the edge where the chip out occurs will reduce the chances of chip out when going in the correct direction to remove the rest of the waste.

One more… When routing around a corner sometimes it is best to backroute around the corner, again taking shallow skim passes.
