Manufacturing Engineering
(2003)
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

This article presents a recently developed mathematical model for Integration of the effects of prior manufacturing steps into heat treatment simulations by considering the modification of the banded microstructure in forming and machining processes. The model was justified by simulating the heating, austenitizatlon and quenching of dilatometer specimens machined from the forged discs with distinct orientations to the banded microstructure. Then, It Is tested In prediction of dishing of blank-hardened gear blanks, which cannot be reproduced by previously available models. The model provides promising results for process chain simulation and development of system-oriented measures for the solution of heat treatment distortion problem. © 2011 Wiley-VCH Verlag GmbH & Co.
