SEÇİCİ LASER ERGİTME YÖNTEMİ İLE ÜRETİLMİŞ DIN 1.4404 MALZEMENİN EDM İLE İŞLENEBİLİRLİĞİ

Bu çalışmada, diş protez ve implant üretiminde sıklıkla kullanılan, Seçici Lazer Ergitme metodu ile üretilmiş AISI 316 L (DIN 1.4404) malzemenin Elektro Erozyon yöntemi (EDM) ile işlenebilirliğinin araştırılması için deneysel çalışmalar gerçekleştirilmiştir. Deneylerde bakır ve grafit olmak üzere iki farklı elektrot kullanılmıştır. Akım (amper, I) ve pulse on-time (µs, ton) değerleri değiştirilerek deney parametreleri oluşturulmuştur. Elektrotlarda meydana gelen aşınma (EW) değerleri, yüzey pürüzlülük (Ra) değerleri ve malzemeden kalkan talaş kaldırma oranı (MRR) değerleri incelenmiştir.

MACHINABILITY OF SELECTIVE LASER MELTED DIN 1.4404 MATERIAL WITH EDM

In this study, experiments were performed in order to research the machinability of the implant material AISI 316L(DIN 1.4404), produced by the Selective Laser Melting (SLM), and Electrical Discharge Machining (EDM) methods. This material is the most frequently used implant material in the production of dentures and dental implants. In the experiments, copper and graphite electrodes were used. Experiment parameters were generated by changing the current (ampere, I) and pulse on-time (µs, ton ) values. After performing the experiments, the relationship between the Material Removal Rate (MRR), Electrode Wear (EW) of the material and Surface Roughness (Ra) values were investigated.
