Oğuz ERDEM [1] , Süleyman KILIÇ [2]


Bu çalışmada işparçası olarak AISI4140 çeliği, elektrot olarak 2 mm dış çapa sahip ortası tek delik bakır tüp, dielektrik sıvı olarak ise yüksek parlama noktasına ve düşük viskoziteye sahip Eurolub EDM ER100 çevreci tip elektro erozyon sıvısı kullanılmıştır. ER100 içerisine farklı derişim oranlarında (katkısız, 5 g/l ve 10 g/l) katılan TiO2 tozunun hassas (M1), orta (M2) ve kaba (M3) işleme koşullarında elektro erozyon ile işleme (EEİ) çıktı performansları (işparçası işleme hızı (İİH), elektrot aşınma hızı (EAH), bağıl aşınma (BA) ve ortalama yüzey pürüzlülüğü (Ra)) üzerine etkileri araştırılmıştır. Dielektrik sıvıya 5 g/l TiO2 tozu katkısı sayesinde her üç işleme tipinde İİH değeri açısından ortalama %30,48’lik bir artış elde edilmiştir. Yine, dielektrik sıvıya 10 g/l TiO2 tozu katkısıyla her üç işleme tipinde ortalama %57,03’lük bir işleme hızı artışı sağlanmıştır. Elektrotu döndürmek İİH değerleri üzerinde M1 işleme tipinde ortalama %99,5 artış sağlarken, M2 işleme tipinde ortalama %13,75 ve M3 işleme tipinde ortalama %9,38 oranlarında artışlara olanak sağlamıştır. TiO2 tozu katkısıyla hem sabit hem de döner elektrotla yapılan deneylerde, M1 ve M2 işleme tiplerinde elektrot aşınması azalırken sadece M3 işleme tipinde litreye 10 gram TiO2 tozu katkılı dielektrikte elektrot aşınmasının arttığı sonucuna varılmıştır. BA değerlerinin tıpkı EAH değerleri gibi özellikler sergilediği tespit edilmiştir. Dielektrik sıvıya 5 g/l TiO2 tozu katkısı Ra değerlerini M1 için %5,27, M2 için %8 ve M3 için %2,95 oranlarında azaltmıştır. Yine, 10 g/l TiO2 tozu katkısı Ra değerlerini M1 için %8,15, M2 için %15,07 ve M3 için %6,21 oranlarında azalttığı tespit edilmiştir.

In this study, AISI4140 steel was used as a workpiece, a single hole copper tube with an outer diameter of 2 mm as the electrode, and Eurolub EDM ER100 environmentally friendly type erosion fluid with a high flash point and low viscosity as a dielectric liquid. The effects of TiO2 powder, which was added to ER100 at different concentration rates (no added, 5 g/l and 10 g/l), on electrical discharge machining (EDM) output performances (workpiece removal rate (WRR), electrode wear rate (EWR), relative wear (RW) and average surface roughness (Ra)) under sensitive (M1), medium (M2) and rough (M3) machining conditions were investigated. By the agency of 5 g/l TiO2 powder addition into the dielectric liquid, an average increase of 30.48% was achieved in terms of WRR in all three machining types. Again, with a 10 g/l TiO2 powder addition into the dielectric liquid, an average machining rate increase of 57.03% was achieved for all three machining types. Rotating the electrode had provided an average of 99.5% increase for M1 machining type on WRR values, while an average of 13.75% increase in M2 machining type and an average of 9.38% increase in M3 machining type. In experiments with both fixed and rotary electrodes with TiO2 powder addition, it has been concluded that electrode wear decreases for M1 and M2 machining types while only for M3 machining type with 10 gram TiO2 powder added dielectric, electrode wear increases. It was determined that RW values exhibit features just like EWR values. The 5 g/l TiO2 powder addition into the dielectric fluid had reduced Ra values by 5.27% for M1, 8% for M2 and 2.95% for M3. Also, 10 g/l TiO2 powder addition was found to reduce Ra values by 8.15% for M1, 15.07% for M2 and 6.21% for M3.
