GENERAL PURPOSE GOmill PRO GOmill PRO Adjustment Factor Table 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 1 Feed Factor KFz 3.58 2.56 2.3 1.84 1.67 1.54 1.25 1.09 1.02 1 0.9 phi [°] 16.26 23.07 25.84 32.86 36.87 40.54 53.13 66.42 78.46 90.00 180.00 NOTE: 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. For an Ae/D ration of 5% or less there is 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 machinability of the material, from difficult to free cutting. To calculate application specific cutting data, please use above Kv coefficient for Calculation example: Final cutting data recommendation: adaptation of cutting speed and KFz for feed respectively. Application: D1 = 14.0mm; Vc new = 80 * 1.30 = 104 m/min P5 material group; Fz new = 0.06328 * 1.25 = 0.0791 mm/th Vc new=Vc*Kv Ae = 20% of D Fz new=Fz*KFz Cutting data recommendation: Vc = 80 m/min; Fz = 0.063 mm/th Adjustment coefficients: ;Kv = 1.30; KFz = 1.25 SOLID END MILLING GOmill PRO - Ball Nose GOmill PRO - Square End GOmill PRO Long • Application Data Recommended Feed per Tooth (Fz=mm/th) is for Side Milling (A).

Lower value of cutting speed is used for high stock removal applications or for higher hardness (machinability) within group. Higher value of cutting speed is used for finishing applications or for lower hardness (machinability) within group. For better surface finish, reduce feed per tooth. kennametal.com C84
