Abstract
The aim of the present study is to investigate the effect of machining parameters on the cutting forces, tool wear, and machined surface roughness of metal matrix nano composite material through dry turning operations. Composites specimens manufactured from aluminum alloy metal matrix and reinforced with different weight fractions of silicon carbide nano particulates were used to conduct the experimental work. Stir-casting method followed by squeezing technique were used to fabricate the nano composites specimens. The machinability tests were conducted through different cutting conditions using carbide inserts tools material. The machinability characteristics such as surface roughness of the machined specimens, types of chip, cutting forces in the direction of main cutting motion, and tool wear were investigated through the experimental conditions. The results showed improve in surface roughness by increasing the cutting speed and the weight fraction percent of the SiC nanoparticulates. On the other hand the main cutting force component as well as tool flank wear were increased by increasing the weight fraction of SiC nanoparticulates. Moreover the force component increased with increasing the feed rate and depth of cut, however the cutting forces were decreased by increasing the cutting speed while the flank wear increase.
