CNC TOOLING GUIDE
Using tools within appropriate machining parameters in particular correct chip load is important. Simply put chip load is the size/thickness of the chip being removed per flute/cutting edge with every revolution of the tool. So going from a 2 flute bit to a 3 flute bit the size of the chip is reduced by 33 if the feed rate or spindle
