Higher value of cutting speed is used for finishing applications or for lower hardness (machinability) within group. Side milling applications — for longest reach (L3) tools, reduce Ae by 30%. For better surface finish, reduce feed per tooth. KOR 5DS Adjustment Factor for Feed and Speed Calculation Ae/D 2% 4% 5% 8% 10% 12% 20% 30% 40% 50% 100% Speed factor Kv 2,1—3,6 1,6—3 1,6—2,5 1,6 1,4 1,38 1,3 1,2 1,1 1 0,9 Feed factor KFz 3,58 2,56 2,3 1,84 1,67 1,54 1,25 1,09 1,02 1 1 NOTE: For an Ae/D ratio of 5% or less there is a range given for speed factor Kv, which allows 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 the machinability of the material, from difficult to free cutting. These calculations are for roughing/semi-finishing cuts when used with the recommended base Fz. For light finishing cuts requiring improved surface quality it is recommended to reduce the base Fz approximately 50% and then apply these factors. To calculate application specific cutting data, please use KV coefficient table Calculation example: Final cutting data recommendation: to the right for adaptation of cutting speed and KFz for feed respectively.
