Feed Rate Guide
Feed rate (Vf) is the linear speed at which the tool advances into the workpiece, expressed in distance per minute. It is derived from the feed per tooth (fz), the number of cutting edges (z), and the spindle speed (n).
Feed Rate Formula
| Vf (mm/min) | = fz × z × n |
|---|
fz = feed per tooth (mm) · z = number of flutes · n = spindle speed (RPM)
Why Feed Per Tooth Matters
Feed per tooth is the chip thickness each cutting edge removes on a single pass. Too low, and the edge rubs rather than cuts, accelerating wear; too high, and cutting forces can exceed the tool's or setup's rigidity. The correct value depends on the tool's flute count, diameter, and the workpiece material — figures specific to EUROCUT tooling are covered below.
EUROCUT-specific recommended feed-per-tooth values by material and diameter are pending final manufacturer confirmation.
