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. y Cutting Conditions for Slot Milling Cutting Speed Width of Cut Depth of Cut Feed per Tooth Insert vc ae ap fz Work Material Hardness Grade/Breaker (SFM) (inch) (inch) (IPT) VP15TF 200 P WH (165 ─ 395) DC <.394 .004 ─ .010 Mild Steel < 180HB VP15TF 200 DC <.394 .004 ─ .006 JM (165 ─ 395) VP15TF 200 DC <.394 .004 ─ .010 Carbon Steel WH (165 ─ 330) 180 ─ 350HB Alloy Steel VP15TF 200 L JM (165 ─ 330) DC <.394 .004 ─ .006 VP15TF 165 DC <.394 .004 ─ .010 WH (130 ─ 260) Alloy Tool Steel < 300HB INDEXABLE MILLING VP15TF 165 DC <.394 .004 ─ .006 JM (130 ─ 260) VP20RT 200 M WH (165 ─ 395) DC <.394 .004 ─ .010 Stainless Steel < 200HB VP20RT 200 JM (165 ─ 395) DC <.394 .004 ─ .006 Tensile VP15TF 165 K WH (130 ─ 260) DC <1.969 .006 ─ .010 Cast Iron Strength VP15TF 165 DC <1.575 .004 ─ .008 <350MPa JM (130 ─ 260) Tensile VP15TF 130 DC <1.575 .006 ─ .010 WH (115 ─ 260) Ductile Cast Iron Strength VP15TF 130 <800MPa JM (115 ─ 260) DC <1.181 .004 ─ .008 VP20RT 115 S WH (100 ─ 165) DC <.394 .003 ─ .005 Titanium Alloy < 350HB VP20RT 115 JM (100 ─ 165) DC <.394 .003 ─ .005 Note 1) The above cutting conditons are determined based on high rigidity machine and work material, where no vibration occurred.
