To Analyze and Study CNC Lathe in Turning Machining Parameters
Abstract: Metal matrix composites (MMCs) consists an important class of design which have weight-efficient structural materials that are inspiring every field of engineering applications. There has been an increasing interest in composites containing low density and low-cost reinforcements. Among various discontinuously dispersed solids used, alumina is one of the most inexpensive and low-density reinforcement available in large quantities as solid waste by-product during combustion of coal in thermal power plants. Hence, …

Parameter Optimization of Electro Discharge Machining of AISI P20 Steel Material
Abstract: In this paper, the cutting of P20 Steel material using electro discharge machining (EDM) with a copper electrode by applying Taguchi methodology has been reported. The Taguchi method is used to formulate the experimental layout, to analyze the effect of each parameter on the machining characteristics, and to predict the optimal choice for each EDM parameter for example peak current, gap voltage, duty cycle and pulse on time. It is …

Snow Compression Property Assessment Using Several Cross-Section Compression Pressure Vessels
Abstract: Effects of the cross-section shape of snow compression pressure vessels on snow compression properties between snow compaction density ρ and axial formation pressure pz were investigated to obtain basic data to support snow compression pressure vessel design. Snow compression pressure vessels with cylindrical, square, and rectangular cross sections were used for those experiments. Results show that the axial formation pressure pz changed from 2.0 to 4.0 MPa. The cylindrical cross …

Stress Intensity Factor in Artificially Damaged Structures
Abstract: The presence of cracks in macrostructures creates heterogeneity which manifests itself by a change of the state of stress and strain in the structure. A crack in vibrating structures can lead to premature failure if it is not detected in time. Researchers have been working on the dynamics of cracked structures for decades to be able to monitor the structure and diagnose that fault at the earliest possible stage. In …

Roller Burnishing Process on Surface Hardness
Abstract: Roller burnishing is the procedure which produces a fine surface finish by the planetary rotation of hardened roils over a bored or turned metal surface. Roller burnishing involves plastic deformation of the surface of the work piece to improve surface structure. The most important parameter describing surface integrity is surface roughness. A detailed experimental program was used in this study where specimens were subjected to various levels of feeding speed …

Review on the Mechanics of Lightweight 3-D Graphene Assembly
Abstract: The purpose of this paper is to improve the results of Recent advances in three-dimensional (3D) graphene assembly, it has shown how we can make solid porous materials which is lighter than air. In its two-dimensional form, graphene is thought to be the strongest of all known materials. But researchers until now have had a tough time decoding that two-dimensional strength into beneficial three-dimensional materials. It is possible that these …

Identification of Axial Air-Foil Bearings and Radial Air-Foil Bearings
Abstract: Air-foil bearings (AFBs) are self-acting hydrodynamic bearings, a shaft is supported by a compliant, spring-loaded foil journal lining. Once the shaft is spinning fast enough, the working fluid (usually air) pushes the foil away from the shaft so that there is no contact. The shaft and foil are divided by air's high pressure which is produced by the rotation which pulls gas into the bearing via viscosity effects. AFBs provide …

The Curvature Effect consideration in Euler beam theory
Abstract: The purpose of this paper is to improve the results of Euler beam theory. Euler beam theory can be used to determine the deflection of beam. But in some cases cross section of beam is not flat-ended, and Euler beam theory only consider the vertical loading, so the effect of curvature is occurred due to normal loading. The method to determine the curvature effect has been developed in this paper, …
