Optimization of Grinding Process Parameters on CNC Grinding M/C using Taguchi Method

In machining operations, one of the most important machining processes is grinding process. It is responsible for producing discrete components with high precision which accounts for one fourth of the total expenditure of machining processes in industrialized nations. So it is very important for us to understood grinding process to improve surface finishing of products. Many researchers and investigators had proved that parameters such as work speed, wheel speed, depth of cut, feed rate, number of passes, etc are responsible for the effect on grinding process. Every parameter should have optimum value for better surface finish. Design of experiments is the best concept for optimization of parameters at the earliest stage of the processes. In this project, response variable selected is surface finish and input parameters selected are depth of cut, feed rate, work speed. Fractional factorial design is to be done by selecting orthogonal array for three factors and their three levels. Optimum grinding process parameters are to be selected using S/N ratios in Minitab software and ANOVA is to be done for identifying most dominating factor among all three parameters.
