Metal matrix composites are widely used in many different military, aerospace, automotive, etc. industries due to their high strength-to-weight ratio, high hardness, and good wear and fatigue resistance. Machining of metal-based composites (MMC) is difficult due to the presence of the reinforcing phase, and therefore the study of various parameters of the machining process of these composites is necessary and inevitable. In this study, we have tried to provide a correct understanding of one of the factors affecting the life of the tool by examining the factors affecting tool wear during magnesium based composite machining. The effect of shear velocity and advancement on three levels and approach angle were also studied on two levels. All tests were performed in dry machining and fluidized machining mode. Finally, the surface roughness was compared between dry machining and lubricating fluid. The results showed that increasing the shear speed increases the lateral side wear of the tool, which is due to the reduction of the formation of the stacked edge. Also, the use of coolant, although reducing the roughness, caused surface oxidation.
