Chip Load Calculator

One of the challenges in getting good CNC cuts is in selecting the best cutting speed (feed rate) and router/spindle RPM. Selection can be facilitated using the guidance provided by manufacturers regarding the best ‘chip load’ for a particular cutter. Since chip load (the size of the chunk of material taken by a tooth of the cutter) reflects the combination of how fast the cutter is moving forward into the material and how fast it is turning (Chipload = Feedrate / [RPM x number of flutes]), it gives you starting point speed values for testing to determine the most suitable parameters for any cutting situation. This Chip Load Calculator simply provides a quick way to explore these values, and is most useful if you know the approximate desired chip load for a particular cutter and material.更多
