The problem with this layout is that it doesn't describe or show the correct use of the chip breaker. Breakng of chips is what happens when the CB is too far back from the edge. Curling is the same issue. A proper placement allows shavings to emerge that are not broken, and at least with the geometry I prefer, they come out pretty much limp and straight. In the Japanese film, you can see the shaving pressing down into the cut. All the breaking does is snap the chip before it gets too long a lever arm, a little like the modern carbide machine tooling that segments chips.

The thing is that I know we know, and the reason for that is because the Japanese stuff works as in the Japanese film. It seems likely that given that CBs have been on western planes for centuries, they were there for a reason; that luck would have dictated someone would discover why; and as I said, I wonder if they were ever free to be set in the cut. As much as I thought everyone knew how they worked, it is hard to force that conclusion down the throat of anyone who resists it, because the evidence is not clear.

I don't really get where David is coming from because he claims to have learned this from the latecomers (sorry don't know who is getting the credit for others work here), yet he was heavy heavy into Japanese planes, I thought.

Since we are copying the Japanese here, could we put in a word for when they don't use breakers?
