Influence of Abrasive Water Jet Turning Operating Parameters on Surface Roughness of ABS and PLA 3D Printed Parts Materials_Crimson Publishers

Image
 Influence of Abrasive Water Jet Turning Operating Parameters on Surface Roughness of ABS and PLA 3D Printed Parts Materials by Fuat Kartal* in Crimson Publishers Abstract In this study, PLA and ABS materials produced by 3D printing with 14mm diameter and 300mm length were processed by turning with abrasive water jet machining. The effect of processing parameters with abrasive water jet on the surface roughness was investigated. The processing parameters are nozzle feed rate (60-210mm/min), abrasive flow rate (150-225g/min), chuck turning speed and nozzle distance. Experimental studies have shown that the increase in nozzle feed rate (from 50 to 200mm/min), abrasive flow rate (from 150 to 225g/min) and nozzle distance (from 3 to 9mm) results in average surface roughness values increased by 26%, 35% and 19%, respectively. It was concluded that the increase in the rotation speed of the mirror (from 75RPM to 225RPM) resulted in a 17% decrease. https://crimsonpublishers.com/eme/pd...

Overview on Reverse Engineering_Crimson Publishers

Image
 Overview on Reverse Engineering by Amit Rakshit* in Crimson Publishers Opinion: Reverse engineering sometimes known as a back engineering which is a process in which machines, aircraft, architectural structures and additional goods are deconstructed to extract design information from them. Reverse engineering involves deconstructing human being components of larger products. Reverse engineering process enables you to settle on how a part was designed so that you can restructure it. Companies over and over again use this move towards when purchasing a replacement part from an original equipment manufacturer is not an alternative. The reverse engineering process is named as such because it involves working backward through the original design process. Therefore, the confront is to gain a working knowledge of the original design. https://crimsonpublishers.com/eme/pdf/EME.000590.pdf For More open access journals in  Crimson Publishers please click on link:  https://crim...

Seismic Resistance of Turbine Equipment of Powerful Nuclear Power Plants_Crimson Publishers

 Seismic Resistance of Turbine Equipment of Powerful Nuclear Power Plants by Serhii Palkov* and Ihor Palkov in Crimson Publishers Abstract: The paper considers the methods of the design analysis of the seismic resistance for the components of operating nuclear power plants in at three-dimensional setting using the finite element method. An algorithm to confirm the seismic resistance of equipment by a calculation method is proposed, and the limits of its application are determined. A mathematical model of the equipment is developed, and an example of the determination of natural frequencies and stresses for a three-dimensional structure is given. Two main types of calculation were used–static and dynamic. The seismic resistance of the equipment was estimated on the example of the K-1000-60/1500 steam turbine condenser and calculated at a seismic intensity of 6 points on the MSK-64 seismic intensity scale. In the course of solving this problem, results of the stress distribution...

Editorial on Additive Manufacturing_Cimson Publishers

Image
 Editorial on Additive Manufacturing by Ananthapadmanaban Dattaguru* in Crimson Publishers Editorial: Additive Manufacturing is a buzz word in technology for the last few years. Most of the manufacturing was being done by both addition and removal of material like casting, welding, and machining. In recent times, mankind has realized that each bit of material saved is very crucial for the health of mother earth. Hence the thrust on additive manufacturing. Though the term additive manufacturing is new, some of the technologies like solid state welding are being used commercially for a few decades. The crucial difference is that CAD models are being generated after laborious research and the final product alone is manufactured layer by layer using additive manufacturing techniques. https://crimsonpublishers.com/eme/pdf/EME.000588.pdf For More open access journals in  Crimson Publishers please click on link:  https://crimsonpublishers.com

A Review on Leader-Follower Based Path Optimization in Vehicle Platooning_Crimson Publishers

Image
 A Review on Leader-Follower Based Path Optimization in Vehicle Platooning by Jeya Mala D* and Pradeep Reynold A in Crimson Publishers Introduction: In self-driving cars, especially when the vehicles are travelling as a cluster in which the first vehicle acts as a leader and the other vehicles act as followers, there is a need for proper communication on the selection of path. This will help the vehicles to reach their destination without any intermittent communication hurdles that leads to accidents and traffic congestions. To achieve this, the vehicles on the road are formed as a platoon in which the first vehicle will send the communication to all the follower vehicles to line up behind the leader. This will help them to automatically form a string formation to stay close to each other on the highway without any traffic difficulties. This survey report gives an overview on how nature inspired techniques could be applied to achieve vehicle platoons to smoothly run on the hig...

Deformation Mechanisms in a NiobiumAdded Zirconium Alloy via Load Relaxation Tests_Crimson Publishers

 Deformation Mechanisms in a NiobiumAdded Zirconium Alloy via Load Relaxation Tests by Murty KL*, Webber KA and Charit I in Crimson Publishers Abstract:  Load relaxation tests have been performed on a recrystallized Nb-bearing Zr alloy sheet in the rolling direction at various temperatures. The strain rate - stress data thus obtained were used to identify the transitional deformation mechanisms in various modulus-compensated stress regimes. Crystallographic texture of the alloys that controls the extent of mechanical anisotropy was determined. Load relaxation tests are also performed in the direction at 45o to the transverse direction in order to characterize the deformation anisotropy. The degree of anisotropy (in terms of the strain rate ratio) is found to increase with the increase in stress exponent values. https://crimsonpublishers.com/eme/pdf/EME.000586.pdf For More open access journals in  Crimson Publishers please click on link:  https://crimsonpublisher...
