Plunge Feed Rate =
(Cutter RPM) ▪ (Number of Cutter Head Blades) ▪ (Endchip)

Example:

Plunge Feed Rate = 405RPM ▪ 24Blades ▪ 0.060mm Endchip = 583.2mm/min

using a Coniflex Plus cutter head. The included tool angle needs to be larger
®
than twice the slot inclination angle in the Coniflex Plus cutter head which is
