Powder Mixed in Non-Traditional Machining Process and its Optimizing Techniques with Different Work Pieces- A Review

This paper provides study of dispersion of nanoparticles, which is distributed uniformly in dielectric fluid used in EDM. The sample concentration of nanoparticles was studied for solution stability. Sample stability was also compared using different stabilizing agent. The Experimentally determined tri-biological performance for stabilized nanofluids was investigated. The stabilized nanofluids was tested for enhanced thermal properties and mixed in non- convention machining process to manufacture intricate profiles, complex cavities in dies and molds that are extremely difficult to machine by conventional machining. This article presents a review of ongoing research and development in NPMEDM. EDM is a machining process, the metal which is hard and difficult to machine materials like inter-metallic materials and composites. Spark erosion in EDM creates a small hole in a piece of materials which is not contact between electrode and work piece. Electrode and Die steel which is electrically conductive. And investigate the potential of NPMEDM for enhancing Material removal rate (MRR), Surface Roughness (SR)/ Surface finish (SF), Tool Wear Rate (TWR)/ Electrode Wear Rate (EWR) etc., Optimization Methods used are Taguchi method, Response surface methodology.
