 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 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...

 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 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 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...

Modeling of carbon nanotube dispersion in the polymer matrix is an important step for understanding the characteristics of composites. For modeling CNTs dispersion in the polymer, a numerical homogenization technique based on the finite element method (FEM) is used. https://crimsonpublishe...

Compression Behavior of Pa-12 Pipes Under Large Displacements by De Almeida LS, de Oliveira TA, Maurício MHP and d’Almeida JRM* in Crimson Publishers: Materials science Polyamide (PA) pipes are being increasingly employed in fluid distribution networks . Most of these pipes is used in underground networks, where overloads can cause large deflections. Excessive displacement can lead to product failure and can cause surface cracks and leakage of the fluid being transported. This condition can be maximized if the pipe is aged due to effects of the environment or of the fluid itself. In this work, the effect of aging PA pipe segments by their exposure to hot water is presented and discussed. The deformation characteristics of the material before and after aging are evaluated. The results indicate plasticization of the pipes due to exposure to hot water, and, thus, the loads required to cause a specific degree of compression, characterized by reduction of the pipe’s diameter, a...
