The pressure of the waterjet influences the overall performance of the
abrasive waterjet cutting system through operational and phenomenological effects.
In this study, the effect of water pressure in surface quality of Mg-based
nanocomposite was investigated. The as-machined surfaces were examined by field
emission scanning electron microscope to determine the surface morphology. The
surface topography of selected nanocomposite was examined and compared. The
results show that the surface quality is better at higher pressure. However, at lower
water pressure, there is too much interaction among the low-energy abrasive particles
and this may cause insufficient material removal. Abrasive waterjet cutting
seems to be promising tool for machining metal matrix composites in terms of no
thermal damages, no micro-structural changes and negligible sub-surface damages
on the machined surface.
