  • 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. Fine grinding or milling reduces the particle size down to as low as 1.0 micrometer (µm) (4 x 10-5in.) in diameter. Ball mills are the most commonly used piece of equipment for milling. However vibratory mills attrition mills and fluid energy mills also are used. Crushing and grinding typically are dry processes milling may be a wet or dry
