Lower value of cuting speed is used for high stock removal applications or for higher hardness (machinability) within group. Higher value of cuting speed is used for finishing applications or for lower hardness (machinability) within group. Above parameters are based on ideal conditions. For smaller taper machining centers, please adjust parameters accordiongly on diameters greater than 12mm. For better surface finish reduce feed per tooth. Side and Slotting milling aplications: for longest reach (L3) tools, reduce Ae by 30%. Sharp corner tools not recommended for sloting aplication. |
