a hydrothermal method for preparation of nano-size zirconia has been studied to optimize the effective parameters (precursor concentration, temperature and time) using response surface methodology (rsm). the synthesized zirconia samples were characterized through x-ray diffraction (xrd), scanning electron microscope (sem) and transmission electron microscopy (tem) analyses to identify mean nano...

The Semantic Link Network model SLN and Resource Space Model RSM are semantic models proposed separately for effectively specifying and managing versatile resources across the Internet. Collaborating the relational semantics of SLN with the classification semantics of the RSM can support richer semantic modeling in applications. This paper introduces the Resource Class Hierarchies into the SLN ...

Background: Electrical Discharge Machining (EDM) is a well-established non-conventional machining process for the machining of electrically conductive and difficult-to-machine materials. But its applications are limited because of the slow machining rate and poor surface finish. Powder mixed EDM (PMEDM) is unitary of the recent progresses in the EDM process in which powder particles mixed in th...

Electrical discharge machining (EDM) is a wellestablished non-conventional machining process, used for manufacturing geometrically complex or hard and electrically conductive material parts that are extremely difficult to cut by other conventional machining processes. But sometimes poor surface finish and low volumetric material removal rate limits its use in the industry. To diffuse this probl...

The Resource Space Model RSM and Semantic Link Network SLN are models of future interconnection environment, and the combination of them forms a rich semantic layer for the next-generation web. This paper investigates the combination between RSM and SLN. The methods of the transformation between RSM and SLN are proposed. From the perspective of transformation, the correlations between the norma...

Metal matrix composites have been widely used in industries, especially aerospace industries, due to their excellent engineering properties. However, it is difficult to machine them because of the hardness and abrasive nature of reinforcement elements like silicon carbide particles (SiCp).In the present study, an attempt has been made to investigate the influence of spindle speed (N), feed rate...

this paper presents the findings of experimental investigations into the effects of cutting speed, feed rate, depth of cut and approach angle on the machinability of titanium (grade-5) alloy. also the comparison for the two different cutting materials inserts polycrystalline diamond (pcd) and cubic boron nitride (cbn) with similar tool geometry for similar machining parameters is also carried o...

This paper presents the optimization of CNC turning parameters for EN 16 steel bar using the Grey Taguchi Method. A plan of experiments based on Taguchi’s L27 orthogonal array was established and turning experiments were conducted with prefixed cutting parameters for EN 16 steel bar using tungsten carbide tool. The turning parameters are cutting speed, feed rate and depth of cut and the respons...
