| Abstract | ||||
| 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. | ||||
