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.
