Mechanical Engineering

2nd National Conference on Recent Trends & Innovations in Mechanical Engineering

The machining process is dependent on the material attributes and the machining parameters. The present work details a point by point test study to optimize the impacts of cutting parameters on Surface Roughness, MRR and cutting forces of Aluminium Alloy 1100 by utilizing Taguchi robust design methodology. The paper additionally deals with the optimization of processing parameters, i.e. Cutting Speed, Feed rate, Depth of cut and Coolant flow rate. Taguchi orthogonal array is formulated with three levels of milling process parameters and various trials are performed utilizing L9 (34) orthogonal array containing nine rows which denotes the nine experiments to be performed and estimations of each parameter was acquired. The nine experiments are performed and the corresponding MRR, cutting forces and surface roughness are found. The Signal to Noise Ratio (S/N) ratio of the predicted value and the corresponding verification test values are valid when compared to the optimum values. It is found that S/N ratio estimation of confirmation test is within the points of confinement of the predicted value and the objective of the work is full filled.
