For other groups, adjust the cutting depth according to the cutting depth factors in the above table.※(2) When performing cutting where cutting chips may cause clogging, such as for rib processing, blind grooves, etc., cutting depth setting should be set by multiplying a cutting depth factor to calculate the cutting depth amount, and this amount should then be reduced to 80% of the calculated value.※(3) Adjust by setting ae to (5 or less)×(ap)×(cutting depth ratio). When performing finishing processing, calculate the theoretical cusp height and set accordingly.※(4) Helical or sloped processing is recommended for the approach method when engraving.※(5) When L/D is 5 or greater: ①The recommended slope entrance angle when engraving is 1° or less. In addition, feed rate should be adjusted to 70% or less of the values in the cutting condition table. ②When slotting such engraving letters, adjust feed rate to 50% or less and ap to 30% or less of the values shown. In addition, processing by reciprocal cutting is recommended.【切込み設定例】EPDRE2030-6-02-ATHの工具でプリハードン鋼（40HRC）をリブ溝等高線切削する場合、【注意】①被削材、加工形状に合わせて、適切なクーラントを使用してください。被削材②この標準切削条件表は切削条件の目安を示すものです。実際の加工では加工形状、目的、使用機械等により条件を調整してください。③機械の回転数が足りない場合は、回転数と送り速度を同じ比率で下げてください。① Use the appropriate coolant for the work material and machining shape.② These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. In actual machining, the condition should be adjusted according to the machining shape, purpose and the machine type. ③ If the rpm of the machine is low, lower the feed rate also to put the rpm and feed rate in the same ratio.炭素鋼・合金鋼120%100%回転数送り速度回転数送り速度高精度切削条件焼入れ鋼焼入れ鋼（45〜55HRC）（55〜65HRC）65%60%回転数送り速度回転数送り速度High accuracy cuttiing conditionsステンレス鋼・工具鋼Stainless steels, Tool steels（25〜35HRC）プリハードン鋼Pre-hardened steels（35〜45HRC）90%80%回転数送り速度回転数送り速度エポックディープラジアスエボリューションEpoch Deep Radius Evolution92(mm)切り込み比率 Ratio to standard depth of cut外径DCTool dia.コーナ半径RECorner radius首下長LUUnder neckWork materialsCutting depth = 0.1 (ap) × 0.8 (cutting depth factor for Group 4 pre-hardened steel) × 0.8 (for closed-area cutting) = 0.064mmCopperCarbon steels, Alloy steels（180〜250HB）High efficiency cuttiing conditionsHardened steelsHardened steels高精度切削条件は93ページを参照してください。Please refer to P.93about high accuracy cutting conditionsmm/min1,4401,1461,1468608605541,4401,1461,1468608605541,4331,1561,4331,1561,4331,1561,4331,1561,4331,1561,4331,4331,4331,1609021,4331,4331,4331,1609021,4331,4331,4331,1609021,4331,4331,1609021,4331,4331,160902高能率切削条件標準切削条件表 Recommended cutting conditions
