Optimization of Turning Process Parameter of CNC Using Taguchi Method

Abstract

The parameters of machining for EN24 can be optimized with the help of Tagauchi’s analysis. EN 24 is Cylindrical in shape and its machining is done mostly on  a CNC machine. The input parameters involved in its machining are cutting depth, speed of cutting and feeding rate. In order to get the best output, Tagauchi’s method optimizes the input parameters. Rate of the removal of material is affected by one of the input i.e., cutting parameters. The optimized input obtained by the desired parameters indicated the S/N ratio. Tagauchi’s method optimizes the parameters of machining in addition to improving the manufactured components quality by statistical approaches. For obtaining the S/N ratio (signal to noise ratio) L9 orthogonal array  is employed and variance analysis is used in order to get the performance trends of turning operations. Cutting depth, speed of cutting, and feed are the three factors that are chosen for the analysis. As per the input parameters and output desired, the process of machining has been done. The sound-noise (S/N ratio) has been calculated and the measurement of rate of removal of material has been measured. The optimum (best) values of input parameters can obtained easily with the help of the graphs of S/N ratio, as discussed in the subsequent sections
