Bu çalışmada talaşlı işlemede kullanılan kesme parametrelerinin NIMAX ve IMPAX (DIN 1.2738) kalıp çeliklerinin yüzey pürüzlülüğü üzerindeki etkileri araştırılmıştır. Değerlendirilen kesme parametreleri kesme hızı (75, 100 ve 125 m/dak), ilerleme hızı (0,05, 0,10 ve 0,15 mm/dev) ve kesme koşuludur (Kuru ve Hibrit Nano Minimum Miktar Yağlama/ Hybrid Nano Minimum Quantity Lubrication – HNMQL). Taguchi’nin L18 (2¹x3²) ortogonal dizisi ve Varyans Analizi (ANOVA) kullanılarak bu parametreler sistematik olarak incelenmiş ve optimize edilmiştir. Deneysel sonuçlar, HNMQL koşulları altında yüzey pürüzlülüğünde önemli gelişmeler ve iyileşmeler olduğunu ortaya koymuştur. NIMAX çeliği için HNMQL koşulları yüzey pürüzlülüğünde %51,35’e varan bir iyileşme sağlarken kesme koşulu %81,6’lık bir oranla en etkili parametre olmuştur. IMPAX çeliği için ise HNMQL koşulu yüzey pürüzlülüğünde %40,2’ye varan bir iyileşme sağlarken, kesme koşulu %72 oranında bir katkı sağlayarak, NIMAX çeliğinde olduğu gibi en yüzey pürüzlülüğüne en çok katkı sağlayan parametre olmuştur. Deney sonuçları incelendiğinde genel olarak NIMAX malzemesi, aynı kesme parametreleri altında IMPAX malzemesine kıyasla %43,68’e kadar daha iyi yüzey pürüzlülüğü sonuçları sergilemiştir.
