In this research, the analysis of the experimental results has been carried out to study the influence of
the following input process parameters; three of the cutting speeds, five of the feed rates and five of
the drill tools (HSS - different point angles-same diameter) on the process responses, i.e. the
delamination factor (df) and the surface roughness (Ra) of the drilled hole. The drilling has been
carried out on the plate of AL/SiCp MMC, with using three of volume fraction ratios. The results
indicated that the delamination factor (df) is increased with the increase of; the feed rate, the tool point
angle, the cutting speed and with the increase of volume fraction ratios. In addition, the surface
roughness (Ra) of the drilled hole is increased with the increase of; the feed rate, the tool point angle
and with the increase of volume fraction ratios, but decreases with the increase of the cutting speed.
