Application of electrical discharge machining for machining of semi-conductor materials
September 23, 2014
FULL TEXT KEYWORDS EDM; Experiment; Boron carbide; MRR; Surface-roughness; DOE. Abstract. In recent years, the research work in material science has encouraged the development of advanced ceramic materials. Boron carbide has many applications in industries for manufacturing of products such as water jet nozzle and abrasive particles. In this paper several experimental tests have been conducted to study the effect of process parameters in machining of boron carbide "B4C" by using the electrical discharge machining process "EDM". The effect of voltage variation, current intensity, on-pulse and off-pulse durations on surface roughness (Ra) and Material Removal Rate (MRR) were studied simultaneously by utilizing the Design Of Experiment (DOE) technique. This research work indicated that the "EDM" process can be used to machine semi-conductor materials such as \B4C" successfully. In addition, it was found that, the quantity of material removal rate and the quality of workpart surface roughness could be affected by the variations of these process parameters. Finally, the experimental results obtained were compared with the published results reported by other scientist, and a good agreement was found between them. © 2014 Sharif University of Technology.

Indian lighting sector upbeat on prospects in LED segment
September 22, 2014
The various measures being initiated by the central government as well as states to promote energy efficient lighting technologies will go a long way in making the Indian lighting industry buoyant and self reliant in the Light Emitting Diode (LED) segment. During an interaction with Projectmonitor on the sidelines of Light India 2014, a b2b trade fair organised by the Electric Lamp and Component Manufacturers' Association of India and Messe Frankfurt, in New Delhi, from September 18 till 21, Secretary General of ELCOMA Shyam Sujan said 27.5 million streetlights across the country were being replaced with LED lights. He added that the demand for LED lighting was being further driven by the distribution of retrofit LED lamps among BPL households under various government schemes. The distribution schemes are expected to generate a demand for 300 million retrofit LED lamps in the next two to three years.
