ChipLoad chip load ipt

Convert IPM, RPM, and flutes into IPT before comparing to a tooling chart

TECHNICAL UTILITY · CHIP_LOAD_IPT

Result

Enter values to begin.

ipt = ipm / (rpm · flutes)

How to use this estimate

Compute machining chip load (inches per tooth) from feed rate, spindle RPM, and flute count. How it works: ipt = ipm / (rpm · flutes). Out of scope: material IPT charts; SFM selection; tool coating life; CNC canned cycles. Informational calculation for the stated inputs only. Does not certify code compliance; confirm manufacturer data where it applies.
