Abstract: A recent trend in the design and manufacturing industries is the development of miniaturised components or parts whose sizes are measured in microns. Micro electro discharge machining (μ-EDM) is one of the most promising technologies available for machining of micro components that can perform very precise and accurate machining operation. The quality of the product or cavities machined using μ-EDM process depends on the precisely selection of operating parameters. This article presents a review of μ-EDM process which comprises a brief introduction and its working principle, effect of process parameters and its applications in industries. Higher input of discharge energy significantly enhances the machining rate. However, it also affects the accuracy of cavity as well as tool wear adversely. μ-EDM process is predominantly reported as slow machining process that attracted good number of research concentrating to enhance the process capability by doing modification in machining system.
