The feed rate used on a milling machine depends on the following factors: The depth and width of cut. The type of cutter. The sharpness of the cutter. The workpiece material. The strength and uniformity of the workpiece. The finish required. The accuracy required. The power and rigidity of the machine, the holding device, and the tooling setup.

Selecting a machine with the appropriate range of spindle speeds is a critical consideration. The trends in recent years have been toward coated tooling, smaller tools, shallower depths of cut and higher feed rates. Smaller tools require a higher spindle speed. Faster feeds and speeds deliver better surface finishes.
