Determine the specific chip load per tooth for the material to be machined from the Machinability Charts on pages 23-26. If the chip load per tooth is .004 at the top of the chart, and there are 32 teeth in the cutter, the correct feed rate is .128 per revolutions of the cutter. If the correct speed in revolutions per minute is 88, multiply 88 x .128 = 11.2. Set the milling machine feed in inches per minute to 11.2.
