Chip Load Reference and Calculator

Calculate feed per tooth from table feed, spindle speed, and active cutting edges.

Table feed (mm/min)

Spindle speed (RPM)

Active cutting edges

Feed per tooth

Formula and interpretation

Chip load (mm/tooth) = Feed rate ÷ (RPM × active cutting edges)

Chip load is the programmed feed movement assigned to each active cutting edge. It is a starting value, not a guaranteed chip thickness under every engagement condition.
