The discharge of chips and rigidity of tools by the number of the flutes The number of the flutes is essential part of the performance of end mills. Generally , if there Are few flutes, it is easy to discharge of chips but relatively section areas get smaller so that it makes the rigidity of tools fall down and enable tools to sway on cutting . On the other hand, if there are many flutes , the section areas get larger and rigidity gets higher but the chip capacity goes down owing to lessened the chip pocket and it is easily blocked up by chips. 2. The rigidity of tools by the length of the flute The shorter of the tools, the higher the rigidity and performance of cutting. The length of the flute become twice, the rigidity of the end mills falls to 1/8.Because end mills are the tools to move horizontal, it is important for the rigidity of tools to be in inverse proportion to the length of tools. Using a longer flute that need be is not good.
