Abstract

Bu
çalışmada, Elektro Erozyon ile İşleme (EEİ) tekniğinde işleme haznesine
uygulanan titreşimlerin elektrot köşe aşınma geometrisi ve performans çıktıları
üzerindeki etkilerinin incelenmesi için titreşim frekansı, boşalım akımı ve
vurum süresi gibi farklı işleme koşullarında deneyler yapılmıştır. İşleme
haznesi titreşimli (İHT-EEİ) deneylerde titreşimsiz koşullara göre elektrot
aşınma hızı (EAH) ve bağıl aşınma (BA) değerleri azalmıştır. Deneysel sonuçlara
göre işleme haznesine uygulanan titreşimler elektrot köşe yarıçap değerlerinde
azalmaya neden olmuştur.

Keywords
