Abstract
Nowadays, to increase productivity and improve the technical and geometrical aspects of products, new cutting tools with advanced technology have been developed. On the other hand, each day new engineering and non-engineering materials with unique features and applications turn into the market, which require unique machining methods and cutting tools. Metal matrix composites (MMCs) are one of the modern and developing materials that have gained great popularity in various industries. However, applied research works about the evaluation of their machinability still require additional studies. Amongst, Al-Mg2Si is one of these materials. Therefore, the solution for decreasing the area of wear on the flank size of the cutting tool in the machining of Al-Mg2Si with different percentages of Mg2Si was proposed.  Therefore, at the first step, the cylindrical samples were fabricated by induction casting, each containing a uniform percentage of strontium (Sr) element. Thereafter, a scanning electron microscope (SEM) for image processing and analysis of the cutting tool surface. Finally, it was observed that the Sr element significantly reduced the area of wear land of the tool rake face. In addition, lower wear area was observed at a higher percentage of Mg2Si and cutting speed.
