New manufacturing technologies such as nontraditional manufacturing methods (NMM) were needed recently because of new machining requirements for parts with complex geometries, very narrow machining area and high strength materials and also for very small and delicate parts. Since NMM are diverse and their numbers are increasing with the development of new approaches, selecting the most appropriate one among many NMM requires systematic models which incorporate multi-criteria decision making approaches. In this study, a selection model that uses Fuzzy Analytical Hierarchy Process (FAHP) and Fuzzy Technique for Order Preference by Similarity to Ideal Solution (FTOPSIS) approaches is developed for the selection of the most suitable NMM for a specific application. Furthermore, the effectiveness of the developed approach is evaluated by comparing its results with the ones obtained with non-fuzzy (crisp) versions of the AHP and TOPSIS methods. In this study for selection of NMM, fuzzy logic implemented selection methods are developed and after some case studies it is shown that weights obtained with binary comparisions are more effective for ranking results and FAHP phase is more important than FTOPSIS phase.

INVESTIGATION OF INTERSONIC FRACTURE IN HIGLY CURVED COMPOSITE LAMINATES UNDER QUASI-STATIC LOADING Gozluklu, B.; Uyar, I; Çöker, Demirkan (2014-07-25) In wind energy and aerospace industries, new advances in composite manufacturing technology enable to produce primary load carrying elements as composite materials in wide variety of shapes large such as an L-shape. However, due to the geometry, Interlaminar Normal Stresses (ILNS) are induced once a moderately thick laminate takes highly curved shape. In the curved part of the L-shaped structure, the development of ILNS promotes mode-I type of delamination propagation which is the weakest fracture mode. Thi...
Development of a web-based manufacturing application system for rotational parts Özsüer, Erhan; Anlağan, Ömer; Department of Mechanical Engineering (2003) Developing process plans and part programs rapidly and correctly for CNC machine tools plays a vital role in manufacturing. This study is concerned with the development of a web-enabled virtual design and manufacturing application system for rotational parts. The object oriented methodology is used in the application development. Windows Distributed interNet Application (DNA) architecture which describes a framework of building software technologies in an integrated web and client-server model of computing,...
Development of a new hesitant fuzzy ranking model for NTMP ranking problem ATALAY, KUMRU DİDEM; İÇ, YUSUF TANSEL; KEÇECİ, BARIŞ; YURDAKUL, MUSTAFA; Boran, Melis (2021-10-01) Nontraditional manufacturing processes (NTMPs) bring the processing capabilities such as machining high strength and hard materials with desired accuracies and surface finish to the manufacturing companies. Therefore, there has been a significant increase in the use and number of NTMPs. Hence, choosing a particular NTMP for a specific application turns out to be a complex decision-making problem, which involves conflicting qualitative and quantitative ranking criteria. In recent NTMP ranking literature, it ...
Simulator of an additive and subtractive type of hybrid manufacturing system Dilberoğlu, Mecid Uğur; Yaman, Ulaş; Dölen, Melik (2019-06-24) Additive Manufacturing (AM) facilitates the production of intricate objects despite its weakness in attainable part quality and fabrication speed compared to the conventional manufacturing methods. To alleviate the problems arising as a natural outcome of AM methods, hybrid technologies become viable options by employing concurrent manufacturing procedures, e.g. synergetic additive and subtractive manufacturing (SM) actions. Hybrid workstations have recently opened up new dimensions to 3D-printing industry,...
Development of postprocessor, simulation and verification software for a five-axis CNC milling machine Cengiz, Ender; Gökler, Mustafa İlhan; Department of Mechanical Engineering (2005) Five-axis CNC milling machine tools bring great facility to produce complex workpieces with increased dimensional accuracy and better surface quality in shorter machining times. However, kinematics of five-axis machine tools has a complex form which makes it difficult to operate these machine tools properly. The difficulty arises from the complexity of NC-Code generation and tool path verification. Collision of machine tool or setup components with each other is a severe problem in five-axis machining opera...
