College of Engineering, Kalaburgi, Karnataka, india Mechanical Engineering, K.B.N. College of Engineering, Kalaburgi, Karnataka, india The optimization of machining parameters in the turning operation of metal matrix composite (MMC) is a crucial aspect in the manufacturing process. In this research work, Taguchi Method of optimization is used to optimize the cutting parameters, which include cutting speed, feed rate, and depth of cut. The experiments are carried out according to Taguchi L9 algorithm. The optimization is based on minimizing the surface roughness. The results show that the cutting speed has the most significant effect on the responses, followed by feed rate and depth of cut. It is observed a good agreement between the predicted and actual results, indicating the effectiveness of the Taguchi method  in optimizing the cutting parameters. https://www.materialsciencejournal.org/vol20no1/optimization-of-machining-characteristics-in-turning-operation-of-lm2-al2o3-metal-matrix-composite/ Optimization Metal matrix composite Surface roughness Taguchi method Turning
