feed — Feed rate & modesFeed & dynamics

How cutting feed is set and interpreted (per-min, per-rev, inverse-time).

defaults { feed <f> [per rev | inverse] }   ·   g1 … f<f>

ParameterTypeDefault
ffeed—feed value; mm/min, or mm/rev / 1/min with a mode

A bare feed (`f600`, `feed 600`) is **per-minute** (mm/min). `feed <x> per rev` is **per-revolution** (mm/rev) resolved against the live spindle (turning/threading); `feed <x> inverse` is **inverse-time** (each move finishes in 1/x minutes — 5-axis CAM). A glued `f` address inherits the active mode.
