They are the part of the end mill anatomy that create those sharp cutting edges (sometimes referred to as "teeth"). The number of flutes on your end mill is a crucial parameter that depends mostly on the material you want to cut and on the capabilities of your machine. Indeed, the number of flutes on your end mill will impact:
Keywords - End milling, Process parameter optimization, Particle swarm optimization. I. INTRODUCTION Surface roughness is one of the most important parameters to determine the quality of a product. Surface roughness consists of the fine irregularities of the surface texture, including feed marks generated by the machining process.
A counter argument to using more flutes or inserts is that fewer flutes/inserts are less prone to chatter. A single flute end mill will also provide much more chip clearance. This can improve surface finish in materials like plastics which are easily scratched by their own chips. Remove an Insert to Reduce Chatter
End mill diameter Increase diameter of end mill for higher strength-to-length ratio ... Change machine or tool holder or change parameters Too few flutes Use multiflute end mills, use end mill with higher rigidity Excessive cutting Decrease depth and width of cut Lack of accuracy (machine and holder) ...

During contour milling we recommend a lateral infeed of approx. 25 % of the end mill diameter while applying 100 % immersion depth. The immersion depth is conditional to the milling motor, the structure and the stability of the machine. This means a reduction of the values is required, when using a less powerful and / or lighter milling motor.
