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. In the present work the influence of current, voltage and spark on-time on electrode material migration to the workpiece has been investigated. It was found that when the current or voltage is high, a spark with higher energy is produced and mote electrode material is melted and migrated to the work surface. When spark on-time is higher,

Abstract. In the present work the performance of eccentric electrode during EDM has been studied. Material removal rate and tool wear rate increase with increase in spindle speed and feed rate. It was found that higher feed rate increases the wear ratio. Spindle speed values determined the flushing efficiency. A higher spindle speed improves the fl

Abstract. In this chapter the influence of spindle speed and feed rate on electrode wear rate has been described during EDM with an eccentric electrode. It was found that both spindle speed and feed rate causes increase in electrode wear rate.

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

The outcome of the Semenyih By-Election raised several questions on the strength of the political parties post General Election 14. The by-election was important for several reasons, among them was that it was contested in a Malay majority area amidst the growing movement of an UMNO-PAS cooperation to deny PH victory in the area of immediate conseq

This paper evaluates the Kajang by-election held in 2014 from the perspective of the third person effect. The state seat of Kajang was considered important given the poor results obtained by the ruling party, Barisan Nasional, then, a party that lost for the second successive time its two-third parliamentary strength. The Kajang by-election was hel

Carrying out Critical Success Factors (CSFs) analysis is necessary to ensure an organisation or product can be properly developed, sustained, and managed. This paper examines the CSFs of implementing Shari’ah-compliant SIBs (SC SIB) in Malaysia. In doing so, 22 SC SIB CSFs were identified from literature review, consultation with experts, and fee

The writing of history on the development of public relations has been attributed to specific personalities or events of particular countries that have been made universal and hence ignorant of the position in most of the other countries like Malaysia. The PR history in the US identifies specific personalities like Ivy Lee, Edward Bernays and Arthu
