Conventional machining is a form of subtractive manufacturing, in which a collection of material-working processes utilizing power-driven machine tools are used to remove undesired material to achieve a desired geometry. This paper presents an approach for comparison between turning center and vertical machining center by optimization of cutting parameters at cylindrical workpieces leading to m...

Electrical discharge machining (EDM) provides many advantages for the shaping of metallic materials. It also better surface quality Ti alloys used in defense industry. In this study, experiments were carried out with different EDM parameters using Titanium (Gr2) alloy. A number novel industrial processes have been developed as a result advances technology. For product to be developed, these app...

The conventional process of machining nitinol alloy which possesses excess strain hardening and low thermal conductivity makes a complex that leads to extensive wear on the tool inadequate surface quality. Wire-electro-discharge (WEDM) is widely accepted for this involving various input factors, namely, P (pulse-on-duration), Q (pulse-off-duration), C, (maximum-current), V (voltage). Using PSO ...

Abstract Micro slots and textures are created on Titanium (Ti) composites to improve its surface characteristics. Micro-textured Ti generally recommended for bio implants, automobile, aerospace components. In the current research, Ti-B 4 C nanocomposites were prepared by powder metallurgical route. cut surfaces Wire Electrical Discharge Machining (WEDM) Technology varying current, pulse-ON time...

Among all non-conventional micro-machining, electrochemical discharge machining (ECDM) is having high quality of material removal rate with zero residual stress. This machining has been accepted as a highly modern technology in micromachining. In this paper an effort has been done on micro drilling of glass using electrochemical discharge machining (ECDM). A fixed tool and a step down transform...

In recent years, WEDM has been adopted in precision machining as an important alternative method because of its greater flexibility and lower wear cost compared with traditional machining, whereas wire breakage during is unignorable problem that influences the quality efficiency. Therefore, it a research topic considerable interest. This work focuses on exploring reason for breakage. Firstly, b...

INSTRUCTIONS The diameter of silicon wafer becomes larger in order to increase the number of chips per one wafer. For such a larger diameter silicon ingot is mainly sliced by using multi-wire method, in which a long thin wire is used with slurry. In this method, several hundreds of wafers could be sliced at the same time. However there are still problems remained, such as large cracks, slurry t...

correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. in electrical discharge machining (edm), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...
