Alüminyum Profil İmalatında İşçi Sağlığı ve İş Güvenliği

Akça, Yaşar; Koç, Ebubekir; Yılmaz, Fevzi (TMMOB Metalurji Mühendisleri Odası, 2014)

Bir işyerinin kimliğini işyerinin yöneticileri ve çalışanları belirlemektedir. Yöneticilerin tutum ve davranışları işçi sağlığı ve iş güvenliği için çok önemlidir. Düzensiz iş akışı, uygun olmayan çalışma ortamı ve eksik ...

Selective Laser Sintering of Aluminum Extrusion Dies

Koç, Ebubekir; Akça, Yaşar; Öter, Z. Çağatay; Coşkun, Mert (FSM Vakıf Üniversitesi, 2016-12)

In this study, geometric forms of maraging steel dies used in aluminum extrusion were optimized by means of flow dynamics as well as surface quality and mechanical properties of the final part. Maraging steel (MS1) dies ...

Support Optimization for Overhanging Parts in Direct Metal Laser Sintering

Öter, Zafer Çağatay; Çoşkun, Mert; Akça, Yaşar; Sürmen, Ömer; Yılmaz, Mustafa Safa; Özer, Gökhan; Tarakçı, Gürkan; Khan, Hamaid Mahmood; Koç, Ebubekir (Elsevier, 2019)

The present work focuses mainly on the utilization of different support profiles for overhang structures in EOS M290 Direct Metal Laser Sintering (DMLS) machine. Maraging steel (MS1) parts with large overhangs were ...

Investigation of the Effects of Different Heat Treatment Parameters on the Corrosion and Mechanical Properties of the AlSi10Mg Alloy Produced with Direct Metal Laser Sintering

Özer, Gökhan; Tarakçı, Gürkan; Yılmaz, Mustafa S.; Öter, Zafer Çağatay; Sürmen, Ömer; Akça, Yaşar; Coşkun, Mert; Koç, Ebubekir (Wiley Online Library, 2019)

In this study, AlSi10Mg samples produced by the direct metal laser sintering (DMLS) method were applied to heat treatment with different parameters (stress relief and T6). Heat‐treated and as‐built samples were subjected ...

Benefits of Laser Beam Based Additive Manufacturing in Die Droduction

Öter, Zafer Çağatay; Coşkun, Mert; Akça, Yaşar; Sürmen, Ömer; Yılmaz, Mustafa Safa; Özer, Gökhan; Tarakçı, Gürkan; Koç, Ebubekir (Elsevier, 2019)

The aim of this study was to benefit from the novel design and production freedom of laser manufacturing in order to alter the existing design concept of extrusion dies and to resolve the limits in die production. A ...

Classification of Main Faults in the Production Process of Extruded Aluminium Profiles

Al-jabbouli, Hasan; Koç, Ebubekir; Akça, Yaşar (İstanbul Gelişim Üniversitesi, 2015)

Aluminium use has been rising steadily in recent decades. Several different industries are adapting it since its light weight, doable structure and robustness. Aluminium manufacturing runs in three ways; namely: (1) ...
