Study the effects of reinforcing elements on the flank wear when milling Al۵۲۰-MMC

Amongst commercial composites, special attention is paid to metal matrix composites (MMCs). According tothe literature, the fabrication process of such materials with additive particles is still the subject of additional studies.Furthermore, limited studies were reported on the effects of reinforcing elements on the machinability of Al-MMC.Therefore, the effects of reinforcing elements, including silicon carbide (SiC), bismuth (Bi), and tin (Sn) particles on the toolflank wear under lubricated and dry milling of Al۵۲۰-MMC are presented in this work. According to experimentalobservations, the use of Bi and Sn in the matrix structure of the work part led to an almost ۵۰% reduction in the toolflank wear when machining Al۵۲۰ + ۱۰% SiC. Despite the reinforcing elements used, higher flank wear was observedunder dry machining than those recorded in lubricated mode.
