Technological advancement, on the one hand, makes Electrical Discharge Machining (EDM) much faster. One example of that is the presence of Wire Electrical Discharge Machining – High Speed (WEDM-HS) machine, which makes the material removal rate as high as 80 mm/min. On the other hand, it also make Abrasive Waterjet (AWJ) achieve much better quality surface and tighter tolerance. As a result, th...

The high-speed wire electrical discharge machining (WEDM-HS) machine has been more and more favoured by customers for the low manufacturing cost, the degree of automation and the advantages over the WEDM-LS in price performance ratio. However, the processing quality (the precision of form and position and the surface quality) of WEDM-HS is poorer than that of WEDM-LS, and the processing quality...

This paper presents, the experimental study has been made to optimize the process parameters during machining of H-13 by wire electrical discharge machining (WEDM) using Taguchi L9 orthogonal array method. Following input process parameters of WEDM [Pulse-On time (TON), Pulse-Off time (TOFF) and Wire Speed rate (WS) and Wire Tension (WT)] were chosen as variables to study the process output in ...

The present investigation proposes a hybrid technique: Taguchi method, response surface methodology (RSM) and genetic algorithm (GA), to analyze, model and predict vibration and surface roughness in traverse cut cylindrical grinding of aluminum alloy. Experiments have been conducted as per L9 orthogonal array of Taguchi methodology using several levels of the grinding parameters. Analysis of va...

Ti-6Al-4V is an alloy that has a high strength-to-weight ratio. It known as alpha-beta titanium with excellent corrosion resistance. This wide range of applications, e.g., in the aerospace and biomedical industries. Examples alpha stabilizers are aluminum, oxygen, nitrogen, carbon, which added to titanium. beta titanium–iron, titanium–chromium, titanium–manganese. Despite exceptional properties...

problematic dyes extensively used in different industries such as textile, paper, food, plasticsand cosmetics have undesirable environmental effects. white rot fungi demonstrating effective extracellularenzyme system, which is capable of degrading dyes and various xenobiotics. the aim of this study was tooptimize decolorization of reactive blue 19 (rb19) dye using phanerochaetechrysosporium. a ...

Recently, most of the conventional (industrial) materials such as steel, aluminum, and copper are being replaced by composite materials. Among various materials, CFRP material is one popular in many industries due to its excellent mechanical properties like-high strength, high modulus, compressive etc. However, micro hole EDM drilling challenging fiber orientation, uneven distribution conductin...
