FEED PER TOOTH (CHIP LOAD)
Feed per Tooth, or Chip Load, is the thickness of material
removed by each cutting surface. You can calculate Feed per
Tooth given values for Number of Teeth and Cutting Feed.
If the Cutting Feed is not known, the Feed per Tooth can be
calculated given values for Number of Teeth, Feed Rate and
RPM (Spindle Speed).
feed per Tooth –
based on cutting Feed and # of Teeth
