ABSTRACT

Recent trends in the ornamental industry have increased the use of granite for various
decorative applications owing to its outstanding mechanical properties and multicolor.
Machining of granites with conventional systems is costly. Therefore, new technologies
are being developed for cutting and processing applications of granites. Abrasive
waterjet cutting (AWJ) is one of the non-traditional machining processes that have been
used extensively in various industrial applications. It enables to cut materials being hard
to machine such as steel, ceramic, concrete and stone. However, it may cause roughness
and waviness on the cut surface. This significantly affects the dimensional accuracy of
the machined part and the quality of surface finish. In this study, optimization of process
parameters for surface roughness of two granites cut with abrasive waterjet was carried
out based on Taguchi ortogonal design. The conclusions revealed that the abrasive flow
rate and traverse speed were the most influential factors on the surface roughness for
both granites respectively; followed by standoff distance, water pressure and abrasive
size with respect to the granite.
