Abstract. Wire EDM is in use for a long time for cutting punches and dies, shaped pockets and other machine parts. Surface finish of the machined surface mainly depends on current and voltage used during machining. In the present work experimental investigations have been conducted to establish relationships job surface finish with current and volt

Abstract. The present paper reports on the influence of process parameters on surface roughness of mild steel during EDM using a copper electrode. Surface quality was evaluated on the basis of work surface roughness, micro cracks and thickness of the recast layer. Current, pulse-on time, pulse-off time and voltage were the variable parameters for t

Abstract. The present paper reports on the influence of process parameters on formation of micro-cracks and recast layer on mild steel during EDM using a copper electrode. Surface quality was evaluated on the basis of work surface roughness, micro cracks and thickness of the recast layer. Current, pulse-on time, pulse-off time and voltage were the

Abstract. Features of tantalum carbide-copper powder compacted electrodes during EDM of mild steel have been studied. It was found that during EDM electrode wear increases with increase in current and spark on-time. Electrode wear is inversely proportional to spark off-time. Due to increase in off-time, energy density decreases that caused reductio

Abstract. Tantalum-carbide and solid copper electrodes were used to EDM mild steel. Current, spark on-time and off-time were taken as the machining variables. It was found that work surface hardness increases while machining with high current and on-time. However, increase in spark off-time results decrease in work surface hardness. It was also fou

Abstract. The electrical discharge machining (EDM) process parameters (both the input and output) are presented. The input variable of EDM presented here are electrical and non-electrical ones. These are peak current, discharge voltage, pulse cycles (duration and interval), electrode‘s polarity and gap. The recent advances in areas of both the in

Telemedicine is one of the most emerging technologies of applied medical sciences. Medical information related to patients is transmitted and stored for references and consultations. Medical images occupy huge space; in order to transmit these images may delay the process of image transmission in critical times. Image compression techniques provide

The main purpose of the present paper is to document some Islamic leadership principles of management. The paper equally examines the leadership function as adopted by academic administrators within the International Islamic University, Malaysia vis-a-vis Islamic principles of management. The whole process is an attempt to conduct an empirical stud

The slogan, “of the people, for the people, by the people” comes home. Bank Rakyat Malaysia (BRM) offers a different kind of retail banking. Bank Rakyat underwent a drastic evolution from a cooperative system of management to a highly creative market entity ready to face the very aggressive competitive market forces of the Islamic banking and f

The purpose of this study was to examine headmasters' and headmistresses' roles in facilitating learning organization and their perceptions of transformational leadership in primary schools. The study also examined the relationship between the headmasters'and headmistresses' perceptions of transformational leadership and their roles
