The formula is used for milling and drilling applications. Please note that some tool manufacturers provide their recommended feed rate as feed per revolution. In such cases do not multiply by the number of teeth. Code Feed Rate = RPM x N x CL Feed Rate = 800 (RPM) x 2 (teeth) x 0.001 ("chip load) =1.600 (in/min)
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.
