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 study aims to eliminate the off-centric initiation of localization caused by friction in the Nakazima testing of forming limit curves (FLCs). Our proposed approach uses an ordinary Nakazima testing equipment and standard Nakazima geometries for specimens. The principle is based on a layer of relatively thick, flexible and durable polyurethane disc, whose coherent deformation ensures strain localization at the pole. The main advantages of this approach are the simplicity of the equipment and testing, inexpensiveness, and yet the coverage of the entire strain range relevant to sheet metal forming. The technique is validated by experimental and numerical FLC investigations. (C) 2015 CIRP.
