Machining of Aluminium Metal Matrix Composite (Al-MMC) is one of the challenging tasks due to its properties. Prediction of optimum machining conditions by systematic way is a difficult task which can be used for improve the performance of machining as well as sustainability assessment. In this investigation, turning operation is performed on Al-MMC using different machining conditions such as dry condition, wet condition and solid lubrication. Taguchi L9 orthogonal matrix is considered for performing the experiments. Cutting speed, feed rate and depth of cut are considered as input parameters. Output parameter considered is machined surface roughness. Taguchi procedure is adopted for finding optimum process parameters and its significance. The result revealed that solid lubrication is provided better surface finish than dry and wet conditions. It is observed that lower value of surface roughness by reducing the frictional coefficient in solid lubrication than dry and wet conditions. This work is used to find out the suitable machining conditions by statistical approach.
