Finite-Volume Heat Transfer Model of the Nano Electrical Discharge Machining Process

As a modern machining process, Electrical Discharge Machining (EDM) provides various applications in micro-manufacturing. Fast-paced development of nanotechnology and the necessity to benefit from the new techniques have given rise to attraction of interests to use of the EDM process in nanomanufacturing. Nano-EDM process is a thermal machining process in which thermal energy produced by electric sparks is used for machining. Therefore, thermal modeling of the Nano-EDM process is very important for accurate understanding of the process and its better application in nanotechnology. In this study, heat transfer model of workpiece in the Nano-EDM process has been developed using Finite Volume Method (FVM). The impact of variables of the Nano-EDM process (including power and spark pulse duration) and workpiece thickness (100 and 300 nm) on temperature distribution in the workpiece were analyzed.
