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 research data. Here the Minitab 16 software is used to analyze the MRR performance. 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.

Metal Matrix Nano Composite (MMNC) Now a day’s nano-sized particles application is on the increasing because it maintains the ductility and strengthens of Metal Matrix composites (MMCs).MMCs reinforced with ceramic nanoparticles (less than 100 nm) has been termed as Metal Matrix Nano Composites (MMNCs) [1]. Aluminum-based metal matrix composites are developed for low-weight high-strength and better wear resistance applications in aerospace, automotive industries.[2] Even with a low volume fraction of nanoparticles increases the properties of MMNC. Dual reinforcement composites possess better properties when compared with single reinforced composites. [3].Experimental investigation has shown increase in weight % MWCNTs improving micro hardness and density. Aluminum metal matrix reinforced with B 4 C and MWCNT was successfully synthesized using sintering [3]. The requirement of the EDM machining such as B 4 C embedded specimen, due to fairly long spark for Revised Manuscript Received on November 15, 2019 S.Dhandapani, Mechanical Engg Dept, Rajalakshmi Engineering College, Thandalam, Chennia- Tamil Nadu, India- 602501 T.Rajmohan Mechanical Engg Dept Faculty of Engg & Tech, SCSVMV University,Kanchipuram,TN,India-631561 D.Kumar, Mechanical Engg Dept, Arjun Colege of Engg & Technology, Coimbatore,TN,India. removing material which has hard particles [4]. Powder metallurgy techniques is found which as one emerged and excellent routes for the fabrication of MMNC. In this work, planetary ball milling was used for dispersing 2 wt% MWCNT in aluminum (Al) powder [5]. Commented in his work keeping Pulse on time, Duty factor, Current, Voltage as constant and by varying two parameters such as Grain size and concentration of Al powder the MRR and surface roughness have a great influence.[6] B. Design of Experiments (DOE) -Taguchi Method Taguchi method uses a special design of orthogonal arrays to for study of the entire parameter space with a limited number of experiments. The experimental results are then transformed into a signal – to – noise (S/N) ratio for measuring the quality characteristics deviating from the desired values [7]. The experimental confirmation test is the final step for validating the results drawn on the basis if Taguchi’s designs approach as considered [8]. A researcher optimized using this approach and set the optimal conditions for the significant factors (the insignificant factors are set at economic levels) and a selected number of experiments are run under specified cutting conditions. The average of the results from the con-formation experiment was compared with the predicted average based on the parameters and levels tested [9]. C.Material Removal Rate (MRR) The material removal rate of the work piece is the volume of the material removed per minute. The equation for MRR is calculated MRR= (Wi-W f )*100/D w *t ------ [10] MRR – Material Removal Rate (mm3/min) , W i - Initial weight of work piece (gm),Wf - Final weight of work piece (gm) Dw - Density of the work piece (gm/cm3), t - Period of trial (min) II. EXPERIMENTAL PROCEDURE A. Powders and mixtures Atomized aluminum powder of 99.5% purity, B 4 C (150 μm) powders and MWCNT (50-80nm are used as initial material for fabrication process. The chemical composition of powders used in the investigation is presented in. In 3 synthesized and characterized by preparing two mixtures of varying MWCNT content (1% and 2%) for his experiment. A researcher identified that homogeneous mixing of powders according to the wt%, plays a vital role in achieving the desired properties of the composite [11]. Using the ball milling for achieving a homogeneous mixture and better bonding between powders of varied mixture. Ball milling was made to one hr for each powder mixture with a quenching time of 10 min for every half an hour.
