【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。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）apは被削材グル−プ2での目安を示しています。その他のグループの場合は、上表の切込み比率を目安に調整してください。
※（２）リブ加工や止まり溝など、切りくずがつまりやすい切削の場合、切込み設定は基本切込みに切込み比率をかけて算出した切込み量を、
さらにその80％まで小さくして使用してください。
※（３）aeの設定はap×切込み比率×5倍以下を目安に調整してください。仕上げ加工を行う場合、理論カスプハイトを計算し設定してください。
※（４）掘り込み時のアプローチ方法は、ヘリカルか傾斜での加工を推奨いたします。
※（５）L/Dが５以上の場合、
①彫り込み時の傾斜進入角は1°以下を推奨いたします。また、送り速度は条件表の70%以下に調整してください。
②文字彫り加工のような溝切削の際は、送り速度は50%以下・apを30%以下を目安に調整してください。また往復切削による加工を推奨いたします。
【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、
切込み=0.1（ap）×0.8（プリハードン鋼グループ4の切込み比率）×0.8（閉鎖域の切削）=0.064mm
① Use the appropriate coolant for the work material and machining shape.
※(1) ap is shown as the criteria for Group 2 workpieces. 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.
Cutting depth setting example: When cutting rib groove contours in pre-hardened steel (40HRC) using an EPDRE2030-6-02-ATH tool:
【Note】
Cutting depth = 0.1 (ap) × 0.8 (cutting depth factor for Group 4 pre-hardened steel) × 0.8 (for closed-area cutting) = 0.064mm

【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。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）apは被削材グル−プ2での目安を示しています。その他のグループの場合は、上表の切込み比率を目安に調整してください。
※（２）リブ加工や止まり溝など、切りくずがつまりやすい切削の場合、切込み設定は基本切込みに切込み比率をかけて算出した切込み量を、
さらにその80％まで小さくして使用してください。
※（３）aeの設定はap×切込み比率×5倍以下を目安に調整してください。仕上げ加工を行う場合、理論カスプハイトを計算し設定してください。
※（4）Z切り込み時のアプローチ方法は、ヘリカルか傾斜での加工を推奨いたします。
※（５）L/Dが５以上の場合、
①彫り込み時の傾斜進入角は1°以下を推奨いたします。また、送り速度は条件表の70%以下に調整してください。
②文字彫り加工のような溝切削の際は、送り速度は50%以下・apを30%以下を目安に調整してください。また往復切削による加工を推奨いたします。
【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、
切込み=0.1（ap）×0.8（プリハードン鋼グループ4の切込み比率）×0.8（閉鎖域の切削）=0.064mm
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.
※(1) ap is shown as the criteria for Group 2 workpieces. 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.
Cutting depth setting example: When cutting rib groove contours in pre-hardened steel (40HRC) using an EPDRE2030-6-02-ATH tool:
【Note】
Cutting depth = 0.1 (ap) × 0.8 (cutting depth factor for Group 4 pre-hardened steel) × 0.8 (for closed-area cutting) = 0.064mm
