Study of tool flank wear and surface quality in milling of Al520-MMCs reinforced with SiC and Sn particles

Composites are materials with at least two combined materials, one of which is added to the base material to increase its valuable properties. This study is also about one of the widely used composites called aluminum metal matrix composites (Al-MMC) and additional reinforcing materials, including Tin and Silicon carbide (SiC, Sn) particles. These composites have excellent features such as high hardness and strength and are lightweight, while they also pose low machinability. As a result, to improve the current conditions, this study was conducted with the approach of Al520 base composite machining and statistical analysis of the effect of cutting parameters on tool flank wear and surface quality after machining. Based on the investigations, it can be concluded that the defined cutting parameters had an excellent and good effect on tool flank wear. On the other hand, when studying the tool flank wear during the machining of such composites with reinforcing particles of SiC, Sn, the cutting speed always has the most significant effect, and the feed rate and lubrication method, as well as the amount of depth of cut, have the least effects on the flank wear size.
