Comparative assessment of material removal rate in carbon fibre reinforced aluminium foam epoxy novel composite mixed with dried dates powder machined by abrasive waterjet and drilling process

This research work is about comparing the material removal rate (MRR) obtained from abrasive waterjet and drilling processes. The material used for this work is carbon fiber reinforced aluminium foam epoxy composite filled with dried dates powder. Abrasive waterjet is set as an experimental group and the drilling process is a control group. Totally 40 samples were machined by using selected parameters for an abrasive waterjet and drilling. The mean material removal rate obtained for the drilling process is 13.3260 g/min, whereas it is 8.5690 g/min for the abrasive waterjet with the significant value is 0.008 (P
