Web of Science A review of the current state of abrasive water-jet turning machining method(2017.01.01) Kartal, FPublication A review of the current state of abrasive water-jet turning machining method(2017-01-01) Kartal F.; Kartal, FAbrasive water-jet turning (AWJT) is one of these alternative methods and has gained an important status among others in a very short period of time. AWJT becomes prominent with its flexibility in cutting materials with almost any properties, with the elimination of thermal effects during the process, and with minimal stresses it imposes. It is widely preferred when heat-affected zones are to be avoided as it is a cold process. AWJT, on the other hand, is the replacement of a traditional cutter head of a turning testing apparatus with the AWJ in order to remove material turning the workpiece using a spindle testing apparatus while moving the nozzle on an axis with a specific distance from the workpiece. It is convenient to machine planar workpieces using the AWJ while it is harder to machine (turn) workpieces. However, there are scientific studies on the machinability of the planar workpieces, studies on the machinability of cylindrical materials are rarely found in the literature. Among the machining parameters for AWJT are nozzle feed rate, spindle speed, abrasive flow rate, pump pressure, abrasive size, and standoff distance. The studies available in the literature focus on the impact on Ra (μm), machining depth (mm), and material removal rate (mm3 min−1) as experiment outcomes. In this study, reviews of the research are available in the literature on the turning of workpieces using abrasive water jet. This study will also discuss the recommendations for the future research.Web of Science Determination of Fatigue Life and Failure Location of Vehicle Cylindrical LPG Fuel Tanks(2016.01.01) Kartal, F; Kisioglu, YWeb of Science Effect of abrasive water jet turning process parameters on surface roughness and material removal rate of AISI 1050 steel(2015.01.01) Kartal, F; Gokkaya, HWeb of Science Effects of machining parameters on surface roughness and macro surface characteristics when the machining of Al-6082 T6 alloy using AWJT(2017.01.01) Kartal, F; Yerlikaya, Z; Gokkaya, HWeb of Science Evaluation of explosion pressure of portable small liquefied petroleum gas cylinder(2020.01.01) Kartal, FPublication Evaluation of explosion pressure of portable small liquefied petroleum gas cylinder(2020-06-01) Kartal F.; Kartal, FThis study aims to estimate the explosive pressures and permanent volume expansion of liquefied petroleum gas (LPG) portable small LPG cylinder fuel tanks using experimental and finite element analysis (FEA) approaches. Experimental explosion testing was carried out by means of a hydrostatic device in which the cylinders were pressurized with water. LPG tanks are subjected to increased internal equal pressure in FEA modeling. Three-dimensional nonlinear models were developed and evaluated under irregular boundary conditions. For analysis, the required real shell properties including the source region and thickness variations were investigated. Therefore, the results of burst pressures and volume expansions are predicted and compared with the experimental ones. The results of finite element method showed similar results with the results obtained from the experiments. The results provide a description of the stages of the explosion and the hazards arising from the damage to the tanks.Web of Science Fatigue Performance Evaluations of Vehicle Toroidal Liquefied Petroleum Gas Fuel Tanks(2017.01.01) Kartal, F; Kisioglu, YWeb of Science High-quality c-axis oriented non-vacuum Er doped ZnO thin films(2016.01.01) Asikuzun, E; Ozturk, O; Arda, L; Tasci, AT; Kartal, F; Terzioglu, CWeb of Science Investigation of Surface Roughness and MRR for Engineering Polymers with the Abrasive Water Jet Turning Process(2016.01.01) Kartal, F; Yerlikaya, ZWeb of Science Non-traditional Machining of Inconel 600 Material(2019.01.01) Kartal, F; Hloch, SWeb of Science Optimization of Abrasive Water Jet Turning Parameters for Machining of Low Density Polyethylene Material Based on Experimental Design Method(2014.01.01) Kartal, F; Cetin, MH; Gokkaya, H; Yerlikaya, ZWeb of Science Performance evaluation of the submerged abrasive water jet turning process for improving machinability of castamide(2020.01.01) Ibrahim, SAB; Korkmaz, S; Cetin, MH; Kartal, FPublication Study and evaluation of abrasive water jet turning process performance on AA5083(2020-02-01) Kartal F.; Kartal, FIn this study, the effect of processing parameters on surface roughness and macro surface characteristics was analyzed during the machining of Ø30 mm and 300 mm aluminum alloy AA5083 abrasive water jets. As the processing parameters (up to 10 mm min−1, 15 mm min−1, 20 mm min−1 and 25 mm min−1), abrasive flow rate (50 g min−1, 150 g min−1, 250 g min−1 and 350 g min−1), the lathe chuck rotational speed (25 min−1, 50 min−1, 75 min−1 and 100 min−1) and the nozzle approach distance (2 mm, 5 mm, 8 mm and 11 mm) were used in experiments. In experimental studies, the pump pressure (360 MPa) was used as a constant, in the form of an abrasive Garnet (100 mesh), and the nozzle diameter as 0.76 mm. According to the findings, the best results in terms of surface roughness were obtained as a result of turning speed and abrasive flow rate. When the macro surface characteristics were examined, it was found that the lathe chuck rotational speed increased, the rate of nozzle progression was low, the rate of abrasive flow was high and the nozzle approach distance was lower and the smoother surfaces were obtained.Web of Science THE EFFECT OF PROCESS PARAMETERS ON MACHINING VOLUME AND DEPTH OF CUT IN TURNING OPERATION OF AISI 1040 STEEL WITH ABRASIVE WATER JET(2014.01.01) Kartal, F; Gokkaya, H
