Elektro erozyon ile işleme (EEİ) iş parçası yüzey karakteristiklerinin deneysel incelenmesi

Bu çalışmada, elektro erozyon ile işlemede (EEİ) işleme hızı, elektrot aşınma hızı, bağıl aşınma, krater geometrisi, iş parçası yüzey pürüzlülüğü, mikro sertliği ve mikro yapı özellikleri gibi temel performans çıktılarının işleme parametreleri ile gösterdiği değişim deneysel olarak incelenmiştir. Bu amaçla prizmatik çelik iş parçaları, silindirik bakır elektrotlar ve gazyağı dielektrik kullanılarak değişik dielektrik uygulama yöntemlerinde (püskürtme, emme ve statik) ve işleme parametrelerinde deneyler yapılmıştır. Deneyler sonucunda, işleme parametrelerinin ve dielektrik uygulama yöntemlerinin, temel performans çıktıları üzerinde etkili olduğu görülmüştür.

Experimental investigation on workpiece surface characteristics in electric discharge machining (EDM)

In this study, main machining performance outputs, namely, workpiece removal rate, electrode wear rate, relative wear, crater geometry, workpiece surface roughness, microhardness and microstructure characteristics were experimentally investigated with the varying machining parameters in electric discharge machining (EDM). The machining tests were conducted by using prismatic steel workpieces and cylindrical copper electrodes with kerosene dielectric under different application methods (flushing, suction and static) and varying machining parameters. The experiments have shown that machining parameters and dielectric application methods were effective on main machining performance outputs.
