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 is noted that fuzzy approaches are better suited for handling uncertainties and incomplete information that exist within the NTMP ranking environment. This paper introduces such a fuzzy approach using the hesitant fuzzy preference selection index (PSI) method for the assessment of the criteria weights and the hesitant fuzzy correlation coefficient principle for ranking and recommending the most appropriate NTMP for a specific application. The proposed methodology and its efficiency in dealing with incomplete information under the fuzzy decision-making environment are explored with a case study. As a result of the study, the proposed model preferred the electron beam machining (EBM) as the most suitable nontraditional manufacturing process. On the other hand, triangular fuzzy TOPSIS methods offered the electrochemical machining (ECM) as the best choice among the alternatives. The differences among the ranking decisions are also analyzed in the paper. It can be concluded from the authors' various applications of the proposed hesitant fuzzy PSI method that it is extremely effective in representing fuzzy decision-making environments in NTMP ranking decisions.

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,...
USAGE OF FUZZY MULTI CRITERIA DECISION MAKING METHODS IN SELECTION OF NONTRADITIONAL MANUFACTURING METHODS Kul, Yavuz; Seker, Alper; YURDAKUL, MUSTAFA (2014-01-01) 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 t...
Use of a nozzle with a rectangular orifice on a hybrid FFF system Gharehpapagh, Bahar; Dilberoğlu, Mecid Uğur; Dölen, Melik; Yaman, Ulaş (2021-11-01) Fused Filament Fabrication (FFF) process has lower surface roughness quality, precision and it takes longer to fabricate compared to the conventional manufacturing operations and some additive manufacturing technologies. In order to overcome these issues, a rotary extruder head with a nozzle having a rectangular orifice has been utilized in this work. A new tool path planning for a rectangular nozzle is designed to increase the efficiency of the extrusion process by this nozzle. As a result, finer features ...

A composite dislocation cell model to describe strain path change effects in BCC metals Yalçınkaya, Tuncay; Geers, M.G.D. (IOP Publishing, 2009-11-16) Sheet metal forming processes are within the core of many modern manufacturing technologies, as applied in, e.g., automotive and packaging industries. Initially flat sheet material is forced to transform plastically into a three-dimensional shape through complex loading modes. Deviation from a proportional strain path is associated with hardening or softening of the material due to the induced plastic anisotropy resulting from the prior deformation. The main cause of these transient anisotropic effects at m...
