ANALYSIS AND OPTIMIZATION OF SURFACE ROUGHNESS IN CNC MILLING MACHINE USING GENETIC ALGORITHM

Mechanical Engineering

Owing to the significant role that machining parameters play in performing successful and efficient machining operation, determining of the best or optimum machining parameters is still the subject of many studies. By optimization of various parameters of CNC milling process like spindle speed, feed rate and depth of cut, improvement can be achieved in surface finishing. Here Genetic Algorithm will implemented for better and nearest result. Number of experiments will done by using CNC milling machine. An L9 Taguchi standard orthogonal array (OA) will choose for design of experiments and the main influencing factor will determined for each given machining criteria by using Analysis of variance (ANOVA). The predicted values are confirmed by using validation experiments.
