### Feed Rate CalculatorDaycounter

Feed Rate Calculator. When milling or drilling or creating a tool path for a CNC machine the feed rate must be determined. Materials have rated surface speeds for a given type of cutter. The harder the material the slower the speed. Given the diameter of the tool and the surface speed the RPMs of the spindle can be calculated. Milling Speed and Feed Calculator Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation as well as the cut time for a given cut length. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth such as an end mill or face mill.
