Abstract
Bu çalışmada, günümüzde hızla gelişen ve büyüyen hazır elektrik kablosu imalat sektöründe terminal çakım (krimpleme) işleminin kalite tespitinde kullanılan analiz yöntemlerinin ve analiz için kullanılan cihazların araştırılması planlanmıştır. Elektrik kabloları hem veri alışverişinde hem de elektrik akımının iletiminde kullanılmaktadır. Bu nedenle montajının her zaman kolay ve güvenilir bir şekilde yapılması istenir. Bunun için kablonun ucuna terminal adı verilen bağlantı elemanı yerleştirilir. Bu işleme terminal çakımı (krimpleme) adı verilir. Terminal çakım işlemi sıkma pensesi yardımı ile manuel olarak ya da yarı otomatik veya tam otomatik makineler ile gerçekleştirilebilir. Ancak yapılan işlem her zaman istenilen kalitede gerçekleştirilemeyebilir. Kalitesiz çakım işlemi sonucunda veri iletiminde kayıplar yaşanabilir. Elektrik akımının iletiminde ise kötü temas sonucu kablo ısınmaları, patlama, yangın gibi istenmeyen olaylar olabilir. Bu nedenle yapılan terminal çakım işlemlerinin kalitesinin belirlenmesi için bazı kalite kontrol cihazlarına veya tasarlanacak test platformlarına ihtiyaç duyulmaktadır. Mevcut kalite kontrol cihazlarında çakım kalitesinin belirlenmesi temel olarak elektriksel test, kesit görüntüleme ve kuvvet analizi yöntemleri ile yapılmaktadır. Bu çalışmada kablo işleme endüstrisinde çakım kalitesini belirleme yöntemleri ve araçlarının karşılaştırmalı analizi yapılmıştır. Çakım işlemlerinde karşılaşılabilecek hatalar ve özellikleri ortaya konularak, tahribatlı/tahribatsız kalite kontrol tekniklerinin tercih nedenleri, avantaj ve dezavantajları özetlenmiştir.

Abstract
In this study, it is planned to investigate the analysis methods and devices used for analysis in the quality determination of terminal crimping in the rapidly developing and growing ready-made electrical cable manufacturing sector. Electric cables are used both in data exchange and transmission of electric current. For this reason, it is always desired that its assembly be done easily and reliably. For this, a connection element called terminal is placed at the end of the cable. This process is called terminal crimping. Terminal crimping can be performed manually with the help of crimping pliers or with semi-automatic or fully automatic machines. However, the process may not always be performed in the desired quality. Losses in data transmission may occur as a result of poor quality crimping. In the transmission of electrical current, undesirable events such as cable heating, explosion, fire may occur as a result of bad contact. For this reason, some quality control devices or test platforms to be designed are needed to determine the quality of the terminal crimping operations. Determination of the crimp quality in existing quality control devices is mainly made by electrical testing, cross-sectional imaging and force analysis methods. In this study, comparative analysis of methods and tools for determining the crimp quality in cable manufacturing industry has been made. Defects that may be encountered in crimp processes and their characteristics are revealed, and the reasons for preference, advantages and disadvantages of destructive/non-destructive quality control techniques are summarized.
