Keep your high-feed mills as engaged as possible across the full diameter or less than half the insert width One of the reasons these mills work so well is because their cutting forces are directed at the machine spindle in the axial direction to create balance If you use the same cutter and only engage it 50 or 60 percent of the diameter you will experience push and increased vibrations

A dry run will reveal the actual feed rates Basic physics dictates that maintaining the desired feed rate and chip load 100 percent of the time is not possible A good rule of thumb is If the programmed feed rate is not maintained for 80 percent of the cycle time then spindle speed must be reduced accordingly to maintain consistent chip load

To increase the metal removal rate the stepover is substantially reduced from the typical 50% of tool diameter but the feed rate is increased in order to maintain the correct chip thickness Because the cutting force is reduced you can mill with a much larger depth of cut with a solid end mill plus get better utilization of the full side of the tool
