Chip load is generally the thickness of the chip, and is approximated in practice
by the "feed per tooth". So, if a 4-tooth cutter is turning at 1500 RPM, and
the feed is 15 IPM, then you have a feed per rev of .01", and a feed per tooth
of .0025". Small end mills may use a feed per tooth of .0007", a 1/2" end mill
might use .005" feed per tooth on aluminum, for instance.
