For better surface finish, reduce feed per tooth. Above parameters are based on ideal conditions. For smaller taper machining centers, please adjust parameters accordingly on >12mm diameter. MaxiMet & KenCut AL/ALR-Series • Adjustment Factor for Feed and Speed Calculation SOLID END MILLING 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 Calculation example: Final cutting data recommendation: table to the right for adaptation of cutting speed and KFz for feed Application: D1 = 20mm; Vc new = 1500 * 1,4 = 2100mm/min respectively. N2 material group (Maximet ABDE); Fz new = 0,180 * 1,67 = 0,301mm/z Ae 2,0mm (Ae = 10% of D1) Vc new = Vc * Kv Cutting data recommendation: 1500m/min; Fz new = IPT * KFz Fz = 0,180mm/z Adjustment coefficients: Ae = 2,0mm equals 10%; Kv = 1,4; KFz = 1,67 C59 kennametal.com
