Alüminyum 6082 Alaşımının Pirinç Elektrot İle İşlenebilirliğinin Optimizasyonu

Abstract

Bu çalışmada Alüminyum 6082 alaşımının dalma erozyon tezgahında pirinç elektrot ile işlenebilirliği incelenmiştir. Deneysel çalışmada Taguchi L₉ dikey dizin deney seti kullanılmıştır. İşleme parametresi olarak boşalım akımı, vurum süresi ve bekleme süreleri kullanılmıştır. İşlenebilirlik deneyleri sonucunda ortalama yüzey pürüzlülüğü, iş parçası işleme hızı ve elektrot aşınma hızı değerleri incelenmiştir. Taguchi tekniği kullanılarak ideal kesme şartları için kontrol faktörleri belirlenmiştir. Kontrol faktörlerinin sonuçlara etkisi varyans analizi yardımıyla bulunmuştur. Deneysel çalışma sonucunda ortalama yüzey pürüzlülüğü, iş parçası işleme hızı, elektrot aşınma hızı üzerinde en etkili parametrenin boşalım akımı olduğu belirlenmiştir. Artan boşalım akım değerinin, ortalama yüzey pürüzlülüğünü olumsuz yönde etkilediği ve elektrotun daha fazla aşınmasına neden olduğu bulunmuştur. Vurum süresinin ve bekleme süresinin ortalama yüzey pürüzlülüğü üzerinde önem seviyesinin olmadığı belirlenmiştir.
