In micro-electrical discharge machining (micro-EDM), dielectric plays a significant role during the machining process as different types of dielectrics have different chemical compositions, cooling rates and dielectric strengths. For this, dissimilar process responses are accounted when machining in EDM at micron level. The present paper investigates micro-EDM characteristics such as material r...

The effect of design parameters on the flow pattern in a three-phase bubble column by means of Computational Fluid Dynamics (CFD) has been studied. The simulations were performed for air-water-glass beads in a bubble column of H = 0.6 m, D = 0.1 m and ds = 0.05 m to study the flow pattern. Eulerian–Eulerian three-phase simulations with kturbulence for liquid phase were carried out using the com...

 In the present paper damped vibrations of non-homogeneous infinite rectangular plate of parabolically varying thickness resting on elastic foundation has been studied. Following Lévy approach, the equation of motion of plate of varying thickness in one direction is solved by quintic spline method. The effect of damping, elastic foundation and taperness is discussed with permissible range of pa...

Abstract Micromachining techniques are being used regularly in various engineering and production sectors such as Micro Electromechanical Systems, Aerospace, Automotive, Electronics Biomedical industries. For Laser Beam Micromachining, highly energized laser beam is focused on a small region of the workpiece surface. As result, it heated up rapidly to sufficiently high temperatures, then materi...
