Magnetic Field Assisted Micro EDM - A Review

Micro Electrical discharge machining commonly called as Micro EDM (μEDM) is a well known non-traditional technology used for machining of very hard and difficult to machine materials which are extensively used in die-production, machining of complex 3D geometrical structures, aerospace now a days. μEDM as the name suggests produces part at micro level but it is very time consuming process with very low MRR. This paper presents a review and insight on Micro EDM, followed by the ongoing research and development using magnetic field (MF) assistance on Micro EDM (MFMEDM). This paper also includes literature review on improvements in performance measures with the application of magnetic field assistance on μEDM. In last section, a summary of the future research directions are also discussed.
