Bu çalışmada kalıp çeliği olarak kullanılan R65 paslanmaz çeliğin Mikro-Elektro Erozyon İşleme (Mikro-EDM) ile delinmesi incelenmiştir. Mikro-EDM işleminde Akım A (3, 4 ve 5 A), darbe süresi (Ton) (3, 4, ve 5 µs) ve Bekleme süresi (Toff) (2, 3, ve 4 µs) faktörlerinin delaminasyon faktörü (FdT ve FdB) ve Kerf açısına (Kº) etkisi araştırılmıştır. Deney düzeni Taguchi metodu L9 ortogonal dizilime göre yapılmıştır. Mikro-EDM işleminde sonuçlara çoklu faktörler etki ettiği için Gri İlişki Analizi (GRA) çoklu karakterizasyon yöntemi kullanılmıştır. En etkili faktörlerin belirlenmesi için ANOVA analiz yapılmıştır. Elde edilen sonuçlara göre en düşük kerf açısı, FdT ve FdB değerleri sırasıyla 0,267 (Kº) 24,259 µs ve 59,534 µs olarak tespit edilmiştir. Taguchi metoduyla tahmin edilen değerlerin %95 güven aralığında (CI) içinde olduğu görüldü. ANOVA analizine göre sonuçlara etki eden en önemli faktör %99,1 katkı oranı ile Akım olarak belirlenmiştir.
