Experimental Studies on Machinability of 14 wt.% of SiC Particle Reinforced Aluminium Alloy Composites

Since metal matrix composites (MMCs) have increasing applications in industries, this paper presents an experimental investigation on machinability of SiCp reinforced aluminium metal matrix composites. 14 wt.% of SiCp reinforcement addition composite was studied in end milling using CVD coated carbide tools under different cutting parameters. By experimental results, the relationships of cutting force and surface roughness with cutting speed and feed were discussed. Some defects concerning surface topography such as ploughed furrow, pits, matrix tearing, etc. were examined by SEM.
