Dijital Işık İşleme Tabanlı Stereolitografi 3b Yazıcı Tasarlama ve Geliştirme
(2020) Sahıb, Mohammed; Tirkeş, Güzin; Akar, Samet
Dijital Işık İşleme tabanlı 3B yazıcı, Eklemeli İmalat (AM) teknolojisini kullanarak doğrudan CAD modelinden bir 3B model üretmek için Bilgisayar Destekli Tasarım (CAD) kullanan bir cihazdır. 3B baskı teknolojilerinin materyal , numuneyi oluşturma yöntemleri, hız ve doğruluk gibi birçok farklı yöntemi bulunmaktadır. Doğru üretim şeklini seçmek, malzeme ve kalitenin gereken seviyeye ulaşması, seçilen teknolojiye bağlıdır. DLP teknolojisi basit yapısıyla tanınır, ancak dikkate değer bir kalite ve esneklik yelpazesi sunar. Tasarlanan 3B yazıcının yeteneğini ispatlamak için farklı CAD tasarımları ile üç tip deney yapılmıştır. Bu deneyler yüzey kalitesi, küçük detaylar ve doğru ölçümler açısından başarıyla uygulanmıştır. Ayrıca, istenen çıktı sonuçlarını doğrulamak için iki farklı test yapılmıştır.

Combined Use of Ultrasonic-Assisted Drilling and Minimum Quantity Lubrication for Drilling of Niti Shape Memory Alloy
(Taylor & Francis inc, 2023) Namlu, Ramazan Hakki; Lotfi, Bahram; Kilic, S. Engin; Yilmaz, Okan Deniz; Akar, Samet
The drilling of shape-memory alloys based on nickel-titanium (Nitinol) is challenging due to their unique properties, such as high strength, high hardness and strong work hardening, which results in excessive tool wear and damage to the material. In this study, an attempt has been made to characterize the drillability of Nitinol by investigating the process/cooling interaction. Four different combinations of process/cooling have been studied as conventional drilling with flood cooling (CD-Wet) and with minimum quantity lubrication (CD-MQL), ultrasonic-assisted drilling with flood cooling (UAD-Wet) and with MQL (UAD-MQL). The drill bit wear, drilling forces, chip morphology and drilled hole quality are used as the performance measures. The results show that UAD conditions result in lower feed forces than CD conditions, with a 31.2% reduction in wet and a 15.3% reduction in MQL on average. The lowest feed forces are observed in UAD-Wet conditions due to better coolant penetration in the cutting zone. The UAD-Wet yielded the lowest tool wear, while CD-MQL exhibited the most severe. UAD demonstrated a & SIM;50% lower tool wear in the wet condition than CD and a 38.7% in the MQL condition. UAD is shown to outperform the CD process in terms of drilled-hole accuracy.
