Abstract
Metal matrix composites of Aluminium are finding increasing applications across a wide range of industries, including the automotive and aerospace industries, amongst others. When a third constituent is added to the metal matrix, the production of the hybrid compound commences. This body of work presents the findings of an investigation into the surface roughness properties of hybrid aluminum metal matrix (Al6061-SiC-Al2O3) composites. Some exper- imental investigations were carried out using a lathe. The stir casting method is a technique employed in the field of liquid metallurgy. In this technique, the base matrix was infused with 4, 8, and 12 percent by weight of SiC and Al2O3 particles, respectively. This allowed for the production of composites. The end-result cast composites were handled with a great deal of care and atten- tion to detail. The parameters such as feed rate, cutting speed, and depth of cut that are known to influence surface roughness were investigated. The findings of the study demonstrated that an increase in feed rate leads to a rise in sur- face roughness, but an increase in cutting speed leads to a decrease in surface roughness.
