SERTLEŞTİRİLMİŞ AISI D3 TAKIM ÇELİĞİNİN CBN PARMAK FREZE İLE YÜKSEK HIZDA İŞLENMESİ

Bu çalışmada, 35 HRC ve 62 HRC sertliğindeki AISI D3 soğuk iş takım çeliğinin CBN kesici takımlar ile işlenmesinde, yüzey kalitesi ve yanal yüzey aşınma değerlerinin karşılaştırması yapılmıştır. Kesici takım performansı kesici ömrü ve iş parçasının yüzey kalitesine göre değerlendirilmiştir. Ayrıca, işlenen malzeme sertliğinin kesici ömrü ve iş yüzey kalitesine etkisi tartışılmıştır

HIGH SPEED END MILLING OF HARDENED AISI D3 COLD WORK TOOL STEEL WITH CBN CUTTING TOOL

ABSTRACTIn this work, high speed end milling of AISI D3 cold-work tool steel hardened to 35 HRC and 62 HRC was investigated using CBN cutting tools. Cutting tool performance was studied with respect to tool life and surface finish of the workpiece. The effect of material hardness on the tool wear and surface roughness was also discussed.
