This increase brings the nutritional problem, which is the most important building block for the maintenance of humanlife, and it is imperative to find a sustainable solution to the problem. The world population, which is 7.7 billion, is estimated to reach 9.7 billion people in 2050, and it is thought that agricultural production should be increased by 70% in order to meet the nutritional needs. The solution to find out how to achieve this agricultural production increase and how it will be permanent in the changing climate conditions today will also reduce the nutritional problem. Traditional farming methods are no longer enough. In some countries, practices are given to increase efficiency and reduce costs with Agricultural 4.0 systems. This practice refers to the digitalization of the agricultural sector. For this reason, it will be possible with the process such as less water, fertilizer, fuel used in production and at the same time to obtain more of the product resulting from production. In this study, the necessity of our country to adopt Agriculture 4.0 practices in order to achieve more efficient, more environmentally friendly, sustainable growth, smart growth based on knowledge, innovation and technology in the agricultural sector was mentioned. At the same time the agricultural sector and that a significant position in terms of exports of agricultural products Netherlands, Taiwan, Israel, Japan, the United States and examined the UK's smart farming practices and experiences in analyzing the overall situation of Turkey is made.</p> 2020-06-21T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL 3D PRINTER DESIGN, MANUFACTURING AND EFFECT OF INFILL PATTERNS ON MECHANICAL PROPERTlES 2020-05-05T20:36:49+06:00 Hande Güler Özgül Onur Tatlı <p>Along with the technological developments, it is an expected situation to discover new developed production methods. Additive manufacturing technologies, such as three-dimensional (3D) printers are one of these methods, allowing direct production of parts with complex geometries that cannot be produced by conventional methods. The most popular and inexpensive method among additive manufacturing technologies is FDM (Fused Deposition Modeling) method. This method is particularly interesting for the manufacture of parts with low production volumes.</p> <p>In this study, a 3D-FDM printer with a print volume of 200x200x210 mm has been designed and manufactured.PLA (polylactic acid) test samples having 2 different infill geometries were produced with the 3D printer. Tensile, three-point bending and charpyimpact tests were applied to these samples to investigate the effect of inner filling geometry on mechanical properties. The inner filling geometries are in the form of grid and gyroid. According to the results, while the geometry with the tensile force is "grid", while the geometry with the maximum bending force is "gyroid".It was concluded that different inner filling geometries do not have a significant impact on Charpy impact strength.</p> 2020-06-21T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL INVESTIGATION OF MECHANICAL PROPERTIES AND INSTABILITY OF AIR-JET TEXTURED PBT YARNS 2020-05-05T16:33:29+06:00 Seren Duran <p>Air-jet texturing mechanically alters the parallel arrangement of the synthetic filaments within the yarn, transforming them into a bulky, spun yarn like structure. In this technique, with the help of the applied overfeed and supersonic airflow, all kinds of filaments can be textured. In air-jet texturing, the textured yarn is subjected to a slight stretch between two feed-roll units after the exit of the jet. The purpose of this stretch is to stabilize the mechanical properties of the textured yarn by anchoring the loops in the core. Some of the loops in the structure of the air-jet textured yarns can be destroyed by the effect of the applied forces. The amount of the loops remaining on the thread is related to the "stability" of these loops. Polyester fibres are synthetic materials that contain ester bonds in their main chains. These fibres are especially preferred in conventional and industrial applications due to their favourable properties. Among all the polyester fibres, polyethylene terephthalate (PBT) is generally used where elastic behaviour is essential. In this study, mechanical properties and instability of the air-jet textured PBT yarns were investigated. The preliminary studies showed that mechanical stabilization over a 6% stretch ratio deformed the yarn structure. For this reason, PBT yarns were textured with 4 different mechanical stretch (0-2-4-6%) and 3 different overfeed ratios (20-40-60%). Yarn counts, mechanical properties and instability of the yarns were investigated. The results were discussed concerning the optical microscope images. It was concluded that increasing the overfeed, increased the looped structure. This leaded an increase in the yarn count and breaking elongation, while a decrease in the elastic recovery. Filaments in the samples with the least looped structure (yarns textured with 20% overfeed) maintained their parallel arrangement regarding the yarn axis. Therefore for these samples, the properties of their molecular structure came into prominence and the best elastic recovery behaviour was observed in this group of samples.</p> 2020-06-21T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL MODAL AND STRUCTURAL ANALYSIS STUDIES OF THE TRANSFER LINE CARRIER CONSTRUCTION 2020-06-21T01:57:08+06:00 Barış VOLKAN <p>In this study, the analysis studies carried out to assist the design stages of the part transfer line to be used in an automobile factory and the experiences gained from these analysis studies are emphasized. These experiences are very important in similar product developments in industrial design. Design and analysis studies carried out prior to manufacturing ensure that production can be carried out without any problems. For this reason, special importance should be given to the design stages in the process and alternative solutions should be created by revising the design in every aspect. Analysis studies should be carried out to select the best design among these solutions. The finite element approach, which is the approach used by today's special analysis software, was preferred in this study. Many analyses were carried out on the model whose boundary conditions were determined and the real-life behaviour of the design was foreseen. In the analysis studies, modal analyses and structural displacements were carried out in order to understand the dynamic behaviours and the stresses will not exceed certain limits. A finite element based simulation software was used in the analysis studies. Here, the importance of design experiences based on past experiences has emerged in the optimization of the design.</p> <p>The design steps to be presented in the paper and the analysis results obtained through the design were also very useful in the prototype manufacturing phase and the transfer line was safely demonstrated. As a result of the trials, the transfer line was delivered to the customer and still fulfils its duty safely.</p> 2020-06-21T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL AN EXAMPLE OF SMED STUDY IN SHEET SHAPING OPERATION 2020-05-08T13:40:03+06:00 Rabia Edis Caner Yalçın Tamer Sınmazçelik Pelin Özzaim Haluk Durali Yiğit Yurdakul <p>SMED, Single Minute Exchange of Dies is an important method used to minimize losses caused by die change during the production process. Especially in the automotive industry, even the seconds are important, carelessly designed dies and long-term die change durations seriously affect the production and reduces productivity. To produce the highest quality in a possible short time is one of the important requirements of today. In this context, the SMED method was used as the main source of this study.</p> <p>In this study, the dies of 6 different products produced in the manual press line in the enterprise are taken as reference. These 6 products consist of 85% of manual production. The products are produced using a maximum of 5 different manual presses. In these pressing process, the die change duration of the products were determined after 3.5 months of observation. These durations were examined in detail and it was determined that the durations stem from die design or clamping equipment used. The improvements that can be made on the dies and the innovations or improvements to be made on the equipment used were determined. Quantitative results were given about the effect of SMED approach on the sheet metal fabrication sector by calculating the earnings that will occur when necessary improvements are made.</p> 2020-06-21T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL AN EXAMPLE OF SCRAP MANAGEMENT STUDY IN SHEET SHAPING OPERATION 2020-05-08T13:23:57+06:00 Rabia Edis Caner Yalçın Tamer Sınmazçelik Pelin Özzaim Yiğit Yurdakul Yasin Yılmaz <p>Sheet metal forming has an important place in the automotive industry today. Design of the dies to be used in shaping and product design is very important parameter to produce with as little scrap as possible using the sheet metal in the most efficient way. It is inevitable that the die and product design, which is made without predicting the amount of scrap for the product to be produced, will cause high waste rate. In the design of both the product and the die, besides the functionality of the product, the effective use amount of the semifinished-product, the amount of waste and scrap should also be taken into account and costed. These approaches significantly reduce the amount of scrap and help to use sheet metal more efficiently and increase the gain.</p> <p>In this study, the locations in the current manufacturing situation and pitch amounts of the high capacity parts produced in the enterprise in the 3.5-month period were examined. As a result of these examinations, the parts that have low sheet metal usage efficiencies are distinguished. For these parts, researches have been made on the position and pitch suggestions proposed in the literature. Part location and pitches have been re-modeled to increase efficiency by reducing the amount of scrap in the computer environment. Thus, examples of more efficient use of semi-finished sheet metal were created and the earnings were calculated.</p> 2020-06-21T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL THE AVIFAUNA OF MARSH BIRDS IN THE RESERVOIRS OF THE KARATAU MOUNTAIN SYSTEM 2020-06-21T04:25:30+06:00 A.Umerbekova, N.Tolbayev <div><span lang="EN-US">The Karatau mountain range is a low-mountain system, does not have natural water sources in the form of lakes. Artificial water objects – water reservoirs – are the only large water bodies where most species of water birds are often found or locating during migration. One of the strategic important water bodies&nbsp; for agriculture of the Karatau mountain range is the Koskorgan reservoir. In addition, the Syrdarya River, one of the largest rivers in Kazakhstan, is the most important waterway in the researched region. During the spring flood of the river, temporary water bodies form on a vast territory, which also contributes to an increase in the species diversity of the avifauna of the region. These two water objects served to research the fauna of water birds. We have researched the main species of avifauna, both nesting and found during migrations.</span></div> 2020-06-21T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL SOUTHEASTERN ANATOLIAN REGIONAL ARCHITECTURE AND ITS REFLECTIONS ON BUILDINGS 2020-06-21T05:11:01+06:00 Elif BENGİSU <div><span lang="TR">Human beings have developed spaces that they need from the first creation to the present and in line with their own wishes. Space is not only a physical phenomenon in which individuals or societies perform various actions, but also a variety of meanings and information depending on the societies' cultures, lifestyles, changes in line with their social structures. Each society has a principle that creates a difference from a unique culture to culture and shapes the spatial space. Besides the geographical, topography and climatic features, the historical development and culture of the city were also influential in shaping the created spaces. The architectural decoration seen in the Islamic Artist, which developed in the regions where Islam was born, had an impact on the development of Islamic ditching science of pre-Islamic civilizations in these regions. In the Southeastern Anatolia Region, where the first settlements in history have been moved from past to present, traditional houses have rich cultural heritage in the development of the courtyard structure. Traditional houses have been created in accordance with the conditions of the region where it is located and it is seen that the basic principle is not to change the space setting. Diyarbakır, Şanlıurfa, Mardin and Gaziantep are the leading places in the Southeastern Anatolia Region that best reflect the residential architecture. The general character of the old Turkish house is the presence of a common unit connecting the units. This common unit varies according to regions as sofa, iwan or courtyard. Its special character is evident with different arrangement of rooms around the common unit.</span></div> 2020-06-21T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL
