So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.

Abstract:

Makine bağlantı elemanları (cıvata, somun, pul, vb.) üretim, bakım, onarım ve montaj işlemlerinin ayrılmaz bir parçasıdır. Daha önce kullanılmış ancak sağlam olan makine bağlantı elemanları yeni işlemlerde tekrar kullanılabilmektedir. Bu nedenle, genellikle bir alanda karışık şekilde toplanmış makine bağlantı elemanları bir ayıklama işleminden geçirilir. Böylece sağlam olan bağlantı elemanları sınıflandırılarak ayıklanır ve kullanılamayacak durumda olanlar hurdaya gönderilir. Bu ayıklama işlemi genellikle insan gücü ile yapılmaktadır. Burada ortaya çıkan insan kaynaklı hatalar ve iş gücü kaybı verimliliği düşürmektedir. Bu çalışmada, karışık halde bulunan makine bağlantı elemanlarını görüntü işleme metodu kullanılarak tür, boyut ve metrik olarak sınıflandıran bir otomasyon sisteminin geliştirilmesi anlatılmıştır. Sistem titreşimli besleyici, konveyör bant, görüntü işleme birimi ve paketleme mekanizması olmak üzere 4 ana birimden oluşmaktadır. Bağlantı elemanları, konveyöre gönderilmek üzere titreşim besleyiciye yerleştirilmektedir. Sıralanmış elemanlar konveyör ile görüntü işleme ünitesine aktarılmakta ve bu ünitede tür, boyut ve metrik olarak sınıflandırılmaktadır. Sınıflandırılmış elemanlar paketleme mekanizmasındaki ilgili kutulara yerleştirilmektedir. Bu işlemler sırasında tüm sistem verileri kayıt altına alınarak bilgisayar ortamına aktırılmakta ve geliştirilen arayüz sayesinde kullanıcının bu verilere ulaşması sağlanmaktadır. İlk olarak, sistemin elektrik ve mekanik tasarımları belirlenen tasarım kriterlerine bağlı olarak gerçekleştirilmiştir. Ardından, grafik kullanıcı arayüzü, kontrol ve görüntü işleme algoritmaları geliştirilmiştir. Mekanik parçaların üretiminden sonra sistemin entegrasyonu tamamlanmış ve fonksiyonel testler başarıyla gerçekleştirilmiştir. Test sonuçları, geliştirilen sistemin görüntü işleme tabanlı sınıflandırma başarı oranının % 90' ın üzerinde olduğunu göstermektedir.

Development of machine connectivity elements
2020

Abstract:

Machinery connector elements (cavata, somun, pul, etc.) It is an integral part of production, maintenance, repair and assembly processes. Previously used but solid machine connectors can be reused in new processes. Therefore, the machine connector elements often gathered mixedly in a field are passed through a drawing process. Thus, the solid connector elements are sorted by classification and those that are unable to be used are sent to the hole. This extraction process is usually done with human power. Here occurring human-caused errors and workforce losses decrease efficiency. This study describes the development of an automation system that classifies the mixed machine connectors in type, size and metric using the image processing method. The system consists of 4 main units, including the vibration power supply, the carrier band, the image processing unit and the packaging mechanism. The connector elements are placed on the vibration feed to be sent to the carrier. The ordered elements are transferred to the image processing unit by the carrier and are classified in this unit as type, size and metric. Classified elements are placed in the corresponding boxes in the packaging mechanism. During these processes, all system data is recorded and transferred to the computer environment and the developed interface ensures the user to access these data. First, the electrical and mechanical designs of the system are carried out according to the design criteria specified. Then, graphic user interface, control and image processing algorithms have been developed. After the production of mechanical parts, the integration of the system was completed and functional tests were successfully carried out. Test results show that the image-based classification success rate of the developed system is above 90%.

Development Of A Machine Fasteners Classification System
2020
Author:  
Abstract:

Machine fasteners (bolts, nuts, washers, etc.) are an integral part of the production, maintenance, repair, and assembly processes. Machine fasteners that have been previously used but are scatheless can be reused in new processes. For this reason, used machine fasteners that are generally mixed in an area are subjected to a sorting process, and those that cannot be used are scrapped. In this process, the fasteners are sorted with respect to their types, sizes, and metrics. This sorting process is usually done with manpower and this leads to errors and loss of labor which diminish productivity. In this study, the development of an automation system that classifies mixed machine fasteners as type, size, and metric using the image processing method is presented. The system consists of four main units: a vibrating feeder, a conveyor belt, an image processing unit, and a packaging mechanism. The fasteners are put in the vibration feeder in order to be sent to the conveyor. The elements lined up are transferred with the conveyor to the image processing unit and are classified as type, size, and metric in this unit. Classified elements are placed in the relevant boxes in the packaging mechanism. During these processes, all system data are recorded and transferred to the computer environment, and the user can access these data thanks to the developed user interface. Firstly, the electrical and mechanical designs of the system are done depending on the specified design criteria. Then, graphical user interface, control, and image processing algorithms are developed. After the production of mechanical parts, the integration of the system is completed and functional tests are carried out successfully. Test results show that the success rate of the developed image processing algorithm is over 90%.
