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 tools with reach >4.5xD, reduce fz by 30% and use lowe range of cutting speed as starting condition. Higher slotting DOC possible with proper pull-out protection, tool holder, machine setup & coolant flow.

For light finishing cuts requiring improved surface quality it is recommended to reduce the base fz approximately 50% and then apply these factors. For an Ae/D ratio of 5% or less there is range given for speed factor Kv, which alows the user to either be more conservative at the lower value or more aggressive with the higher value. This can also be considered based on machinability of the material, from difficukt to free cutting. To calculate application specific cutting data, please Calculation Example: Final cutting data recommendation: use above Kv coefficient for adaptation of cutting Aplication: D1= 12.0 mm Vc new= 80 * 1.30 = 104 m/min speed and KFz for feed respectively.
