Opened in 2003 with the aim to graduate experts in the field of machine-production, our Department is among the firsts in our country to offer education in English. The Manufacturing Engineering program focuses on the manufacturing technologies that shape materials from raw materials to final products by means of analytical, experimental and numerical modeling methods. First Manufacturing Engineering Program to be engineered by Müdek, our department aims to graduate creative and innovative Manufacturing Engineers that are knowledgeable in the current technology, and are able to use production resources in an effective and sustainable way that never disregards environmental facts. As the first Department to implement the Cooperative Education Program at Atılım University in coordination with institutions from the industry, the Manufacturing Engineering offers a practice-oriented approach in education with its laboratory infrastructure and research opportunities. The curriculum at our department is supported by current engineering software, and catered to creating engineers equipped to meet the needs of the production industry.

Abstract

Bu tez, rulman bileziği üreten sıcak dövme kalıplarının ömrünü uzatmak için yapılan çalışmaları içermektedir. Tez kapsamında, malzeme özellikleri belirlenmiş, şekillendirme hızına bağlı değişkenler saptanmış, yeni süreç tasarımları denenmiş, ve farklı dövme kalıp geometrileri ile bilgisayar destekli sonlu elemanlar yöntemi analizleri yapılmıştır. Analizi yapılan tasarımların gerçek kalıplarla ve preslerle denenmesi yapılmış ve sonuçlar raporlanmıştır.
This thesis involves work done to increase service life of hot forming dies which produce bearing rings. Within this thesis; material characterization to the 100Cr6 steel, determination of parameters depending on the deformation rate, trial of new process design alternatives and finite element analysis for different forming die geometries has been carried out. Onsite trials with actual presses are made with the revised dies which were analyzed.
