Feed Rate Calculator Daycounter
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. Then if the tooth load for the cutter is know, and the number of teeth, the feed rate can be determined.
Milling Speed and Feed Calculator CustomPart.Net
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.
