Please adjust processing conditions if the vibration is generated. Note 2) For tools with a cutting edge length of 7.87″ or more, please reduce the cutting speed and table feed by 10-20% and the width of cut by 50%. Note 3) If the cutting angle between the tool and work material exceeds 90º when machining corners ,Reduce the cutting speed and table feed by 10-20% and ae by 50%. Also if possible, set a radius cutting path for corners. yCutting Conditions for Slot Milling Work Material Hardness InsertGrade/BreakerCutting Speedvc(SFM)Width of Cutae(inch)Depth of Cut Feed per Toothapfz(inch)(IPT) P Mild Steel < 180HB VP15TF 200WH(165─395)VP15TF200JM(165─395)DCDC <.394 .004─.010<.394.004─.006 L VP15TF 200Carbon SteelAlloy Steel180 ─ 350HBWHVP15TFJM(165─330)200(165─330)DCDC<.394.004─.010<.394.004─.006 VP15TF 165Alloy Tool Steel< 300HBWH(130─260)VP15TF165JM(130─260)DCDC<.394.004─.010<.394.004─.006 M Stainless Steel < 200HB VP20RT 200WH(165─395)VP20RT200JM(165─395)DCDC <.394 .004─.010<.394.004─.006 K Cast Iron TensileStrength<350MPaVP15TF 165WH(130─260)VP15TF165JM(130─260)DCDC <1.969 .006─.010<1.575.004─.008 TensileDuctile Cast IronStrength<800MPaVP15TF130WH(115─260)VP15TF130JM(115─260)DCDC<1.575 .006─.010<1.181.004─.008 S Titanium Alloy < 350HB VP20RT 115WH(100─165)VP20RT115JM(100─165)DCDC <.394 .003─.005<.394.003─.005 Note 1) The above cutting conditons are determined based on high rigidity machine and work material, where no vibration occurred.
