For other groups, adjust cutting depth based on the cutting depth factors in the above table.(2) In cases in which cutting chips may cause clogging--for example, for rib cutting and blind grooves--set the cutting depth using a cutting depth factor to calculate the cutting depth amount. 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). For finishing cutting, calculate the theoretical cusp height and set accordingly.(4) The recommended slope entrance angle when engraving is 1° or less. Adjust the feed rate to 70% or less of values presented in the cutting condition table.(5) When slotting such engraving letters, adjust the feed rate to 50% or less and ap to 30% or less of the values shown. We recommend reciprocal cutting.0.016 0.013 0.010 0.008 0.046 0.027 0.017 0.016 0.065 0.038 0.024 0.024 0.110 0.070 0.040 0.040 0.020.050.10.2EPDREH2010-2-02-TH3の工具で焼入れ鋼（50HRC）をリブ溝等高線切削する場合、切込み=0.11（ap）×0.85（焼入れ鋼グループ2の切込み比率）×0.8（閉鎖域の切削）=0.075mmCutting depth setting example: When cutting rib groove contours in hardened steel (50HRC) using an EPDREH2010-2-02-TH3 tool:mm/min1,2101,0408407501,2101,1309307501,2101,0408407501,2101,040840750mm/min960820660590960820660590960820660590960820660590mm/min800670540480800670540480800670540480800670540480mm/min720600490430720600490430720600490430720600490430mm/min560470380340560470380340560470380340560470380340123451焼入れ鋼Hardened steels焼入れ鋼Hardened steels24,95022,68018,37016,33024,95022,68018,37016,33024,95022,68018,37016,33024,95022,68018,37016,330【切込み設定例】【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.
