Abrasive water jets (AWJ) technology offers numerous benefits over
traditional cutting methods, making it a focal point in natural
stone-cutting applications. In AWJ cutting processes, the material
removal rate (MRR) is a critical performance indicator for evaluating
the effectiveness of the cutting process. As well as some factors such
as operating parameters, the process is affected by the properties of
both the workpiece (cut sample) and abrasive materials. Understanding
the interplay between these factors can lead to controlling MRR and
therefore cutting performance. For this purpose, in the current study,
workpieces from different rock types (10 pieces) are cut with AWJ using 8
varieties of abrasives (brown and white fused alumina, garnet, plastic
granules, emery powder, steel shot, olivine, and glass beads).
Furthermore, statistical models are developed to provide predictions for
MRR based on the mechanical and physical characteristics of the rocks.
Observations indicate that effective cutting performance is achieved
across all abrasives, excluding plastic granules. Notably, steel shot
and glass beads demonstrate the highest MRR values. A strong linear
correlation between abrasive density and MRR is established.
Additionally, empirical observations revealed that abrasives with
spherical grain shapes (particle morphology) deliver superior cutting
performance compared to those with angular. Moreover, findings reveal
that MRR exhibited an upward trend with increasing effective porosity,
water absorption capacity, and Bohme abrasion loss of the rock while
displaying a decline with escalating Schmidt hardness, strength,
ultrasonic wave velocity, and unit volume weight. The study’s findings
underscore the need for careful selection of abrasive materials to
achieve the desired results in terms of MRR.
