MRR - Performance on EDM Drilling over Nano Composite Material

2019 International journal of recent technology and engineering  
Now a day's more research works are going on performance of MRR on various operations with respect to EDM machining. This research paper is to focus the same on parameters base with Performance measure of Material Removal Rate (MRR) in composite Material (Aluminum, Boron Carbide and Multi Wall Carbon NanoTubes (MWCNT) .The machine used for this research is Sink EDM with drilling operation. .Lots of statistical techniques are available to predict the accurate and reliable result form the

The input parameters selected for the EDM machine are: Pulse on time, pulse off time and voltage. The results were compared with the DOE-Taguchi approach (L9) Orthogonal array - result. [1] .Material Removal Rate was studied along with S/N ratio of Main effect plot, Means and Interaction Plot.[2] From software the main effect plots, residual plots, S/N ratio interaction plots and means was obtained The rapid increase with pulse on for MRR is resulted due to addition of nano powder and linearly increase with peak current. The optimal parameters combination was determined as CNT (1%), Pulse on (10 µs), Pulse off (2.5 µs) and Peak Current (50A) i.e. 1 4 4 2. The experimental results were checked with predicted results and a positive agreement was found. Comparing old studies the optimization values found by this experiment results with more MRR.
