Abstract :In this study, six different MMCs containing Al6061 matrix and Al 2 O 3 reinforcements with particle sizes of 32 µm and 66 µm and weight fraction of 10%, 15% and 20% were produced using the vortex method. Machinability tests were conducted at different feed rates and cutting speeds to determine the surface roughness and cutting forces. Result of the tests indicated that the cutting forces positively correlated with the feed rates. Increasing in the cutting speed result in decrease in the cutting forces. The cutting forces did not remarkably vary with respect to the particle size for the same feed rates. The surface roughness negatively correlated with the particle weight fraction. Better surface qualities were obtained at lower feed rates and higher cutting speeds.Keywords : Metal-matrix composites (MMCs), Statistical properties/methods, Surface analysis, Machining
