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. 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.

In Malaysia, the absence of a law to regulate imbalanced risk allocation and unfair indemnity and hold harmless clauses in oil and gas service contracts should be perceived as a serious problem. Such deficiency leads to the problem of inequality of bargaining power resulting from the dominant position of the operators over the contractors. Moreover

An assortment of techniques has been presented in the area of Speech Emotion Recognition (SER), where the main focus is to recognize the silent discriminants and useful features of speech signals. These features undergo the process of classification to recognize the specific emotion of a speaker. In recent times, deep learning techniques have emerg

Building a system integrates the thoughts of security related issues and raises the concerns about the environment compatibility in order to provide secured environments. Administrating tasks stand behind complex dashboards and gives a view to all theoretical skills on field. Yet, limitations caused by constraints are faced, and to trespass those i

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. During EDM work surface roughness can be influenced by using powder compacted electrodes. The present study shows that surface roughness of workpiece is higher when using TaC/Cu green compacted electrode compared to that produced by pure copper electrode. When using TaC/Cu green compacted electrode, more material is deposited on the workp

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 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
