In this study, the laser milling process was used to investigate the machinability of particle reinforced aluminum matrix composites manufactured by powder metallurgy having different amount of SiCp (5, 10, 20 wt%). In this context, the laser parameters like scan speed and fill spacing were associated with the SiCp amount in aluminum (Al) matrix. According to the experimental results, the scan speed is dominant factor on both milling depth and surface roughness. Also, the reinforcement particle amount (wt%) is the effective factor but there is no detected significant relation between the surface roughness and reinforcement particle amount. However, the change in milling depth has been linearly changed with the increase of reinforcement particle amount.
