Effect of Machining Parameters on Material Removal Rate (MRR) and Surface Roughness in Cylindrical Grinding of Inconel 718
International Journal of Advanced Research Methodology in Engineering & Technology
Cylindrical grinding machining is the most popular machining process of removing metal from a work piece surface in the form of tiny chips by the action of irregularly shaped abrasive particles. It has wide range of applications like automobile, aircraft, and marine industries. Precision and quality have been the critical issues for all these industries. To enhance the quality of machined parts, and to reduce the machining costs and to increase the production rate, it is very important to
... important to select the optimal machining parameters. The success of any grinding operation depends upon the proper selection of various operating conditions like work speed, feed rate, depth of cut etc. Optimization of grinding process still remains one of the most challenging problems because of its high complexity and non-linearity while solving it. This research aims to optimize and analyze cylindrical grinding process on Inconel 718. It has High tensile strength and hardness, high thermal resistance and low machinability. It is emerging in the fields like aerospace, petroleum and nuclear industries. Thus optimizing cylindrical grinding process for this material may reduce production cost in industries. In the present study, L-9 orthogonal array is formed based on Taguchi Design of Experiments and it is used to optimize the effect of cylindrical grinding parameters on the surface roughness and Material Removal Rate (MRR). For all the three levels of input values main effect plot and Signal to Noise (S/N) ratio are obtained. The results of the analysis are evaluated to find the optimum input values for high surface finish with maximum MRR.
