It flows on. It only takes a thou or two to float a chip

That seems reasonable, but:
- the stock is moving MUCH faster than the oil can flow (100 FPM = 20 in
per second). By the time that the oil starts to flow over the cut edge,
the tool is long gone.
- the tool is constantly cutting, so that the chip is in constant (high
pressure) contact with the tool face. How does the oil get between them?

This idea of putting oil on the stock is making less and less sense to
me. I'm beginning to think that it is done because it's always been done.

What makes sense is to put the oil on the tool before starting the cut.
Putting it on the tool during the cut _might_ work (if the oil could
somehow flow under the chip).
