FEED PER TOOTH/CHIP LOAD
-
IPT
Feed per Tooth (IPT), or Chip Load, is the distance that the
workpiece feeds into each tooth on a multi-point cutting tool
as it rotates. You can calculate Feed per Tooth given values
for Number of Teeth and Cutting Feed (IPR). If the Cutting
Feed is not known, the Feed per Tooth can be calculated
given values for Number of Teeth, Feed Rate (IPM) and
RPM (Spindle Speed).
