Elektro erozyon ile delik delmede işleme tamlığının deneysel incelenmesi

İşleme tamlığı, elektro erozyon ile delik delme işlemlerinin en önemli ölçütlerden birisidir ve bu olay aşırı elektrot aşınmalarından dolayı çok önemlidir. Bu çalışmada iş parçaları, kör delikler elde edebilmek için elektro erozyon parametrelerine bağlı olarak işlenmiştir. İşleme tamlığı deneysel olarak işleme derinliği ve deliklerin şekillerine bağlı analiz edilmiştir. Deneysel sonuçlar varyans analizi ve regresyon analizi gibi istatistiksel metotlar ile değerlendirilmiştir. Ek olarak, işleme tamlığını geliştirmek ve en uygun işleme şartlarını belirlemek için grey ilişki analizi kullanılmıştır. Çalışma akımının belirleyici parametre olduğu gözlemlenmiştir. Malzemelerin elektro erozyon ile delme işlemlerinde daha doğru delik şekli elde edebilmek için daha düşük çalışma akımı ve daha yüksek vurum süresi tavsiye edilmiştir.

Experimental investigation of machining accuracy in electrical discharge drilling

Machining accuracy is one of the most important criteria of electro discharge drilling (EDD) processes and this phenomenon is serious due to excessive electrode wears. In this study, the workpieces were machined with regard to EDD parameters to obtain blind holes. The machining accuracy was analyzed experimentally based on machining depth and shape of the holes. Experimental results were assessed by statistical methods such as analysis of variance and regression analysis. In addition, grey relation analysis was used to determine optimal machining condition and to improve the machining accuracy. It has been observed that working current is the determinative parameter. The lower working current and the higher pulse time are suggested to obtain the more accurate shape of the drilled holes in EDD of materials.
