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).
feed per tooth – Based on Cutting Feed and # of Teeth
Calculate Feed per Tooth (IPT) with a Cutting Feed (IPR) of
0.024" for 4 Teeth:
1. Enter the Cutting Feed:
.024gT (IPR)
2. Enter the Number of Teeth:
4gI (#Teeth)
