“…Experimental results showed an increase in both material removal rate and surface roughness using electrode rotation due to an improvement in dielectric flow, which effectively helped remove debris from the gap between the electrode and the part. Finally, the influence of EDM drilling process parameters such as pulse duration, polarity and ignition voltage on material removal rate (MRR), electrode wear, machining time and hole diameter was studied by Kliuev et al [22]. The highest rates of SiSiC material were found with negative polarity at 120 V and a pulse duration lower than 1 µs whereas the lowest electrode wear was reached with positive electrode polarity and pulse duration of 5 µs.…”

“…At greater values of I p , T on and V g ; Ra was found to be the largest whereas it was lowermost at the lowest level of input variables. Kliuev et al [11] executed the experiments over EDM while considering the tool length and tool shape as a measure to examine the reliability of the stochastic algorithm. The number of iterations and convergence rate towards the optimal solution.…”

“…EEİ, termal bir proses olduğu için işparçasının sertlik değerinin işlenebilirlik açısından hiçbir önemi yoktur [5]. Yöntem başlangıçta sadece iletken malzemelerin işlenmesi için tercih edilse de [6], günümüzde geliştirilen yardımcı iletken elektrot metodu ile artık yalıtkan seramikleri bile işlemek mümkün olabilmektedir [7]. SiC [6] ve ZTA-TiC gibi seramiklerin [8] yanı sıra, karbon fiber takviyeli plastikler [9] de artık EEİ yöntemiyle işlenebilmektedir.…”
