Chip Load Calculator (Feed per Tooth)

CORE CNC

Back-solve chip load (feed per tooth) from a known feed rate, spindle RPM, and flute count, useful for checking whether a programs feed rate matches the recommended chip load.

Chip Load (in/tooth)
—
Chip Load (mm/tooth)

Formula: Chip Load = Feed Rate divided by (RPM times Number of Flutes). Also called feed per tooth.

How it works

Chip load (feed per tooth) is the thickness of material each cutting edge removes per revolution. Rearranging the feed-rate formula isolates it so a program can be checked against a tools recommended range.

FAQ

Chip load vs. feed per tooth, same thing? Yes, same value, two common names for it.
