“…Particles are crushed by the kinetic energy of their impact against the hard target surface; thus, the crush characteristics depend on the physical characteristics of the abrasives and the target rock. e diameter reduction for garnet particles is caused by internal cracks during abrasive waterjet cutting [21]. In addition, the crush characteristics of abrasive particles are also affected by the inner shape of the mixing chamber and by interaction with the high-speed waterjet [22].…”

Abrasive waterjet cutting technology has come back into use in the field of rock excavation (such as for tunneling) due to the need for precision construction with low vibration. Because the abrasive particles play an important role in efficient erosion during the cutting process, the abrasive characteristics strongly affect the rock cutting performance. In this study, rock cutting tests were performed with five different coarse (40 mesh) garnets to explore the effect of the abrasive feed rate, physical properties, and particle size distribution on rock cutting performance. In addition, garnet particle disintegration was investigated with garnet characteristics for the abrasive waterjet. The test results indicate that the particle size distribution, garnet purity, specific gravity, and hardness are the most important parameters for rock cutting performance. This study offers better understanding of coarse garnet performance and efficiency according to the garnet characteristics. This should provide assistance in selection of the garnet needed to achieve the desired performance for hard rock cutting.

“…Ti or Mg based MMC [87]. Figure 34 Micro-melting of matrix material after AWJ cutting of Mg-6Al/0.66% Al2O3 MMC at a high cutting speed [87] By adding an additional degree of freedom in the rotational direction of the workpiece, the AWJ process can also resemble the turning operation which combines the advantages of AWJ cutting with the kinematics of a conventional turning process, as shown in Figure 35 [84]. This allows the use of abrasive waterjet as a 'universal tool' to achieve various cylindrical shapes while keeping the advantage of high material removal rate as well as low thermal influence for the machining of MMCs.…”

Metal matrix composites (MMCs), as advanced substitutes of monolithic metallic materials, are currently getting an increasing trend of research focus as well as industrial applications for demanding applications such as aerospace, nuclear and automotive because of their enhanced mechanical properties and relative lightweight. Nevertheless, machining of MMC materials remains a challenging task as a result of their structural heterogeneity which leads to deterioration of the machined surface integrity and rapid tool wear. While prior review papers have concentrated on the other machining aspects (e.g. process modelling and tool wear) of MMCs, none of them has addressed the subject of reviewing workpiece surface integrity aspects in details. This paper presents a detailed literature survey on the conventional and nonconventional machining of metal matrix composites with the primary focus on the aspects related to workpiece surface integrity. The contribution of material mechanical and microstructural properties as well as the material removal mechanism upon the quality of workpiece surfaces/subsurface are discussed along with their influences on the fatigue performance of machined part.

“…The major advantage of the AWJ process is its cold cutting (there is no heat generated during the cutting operation [13]. The process is also capable for larger material removal rate and improved fatigue strength of the machined surface due to the pinning action on the workpiece surface [14]. Machining with AWJ can be applied for turning, drilling and milling as per requirement of the industry.…”

The conventional machining of engineering hard materials like composites is a challenging task due to rapid tool wear and high machining cost. In this context, the non-conventional machining such as abrasive waterjet cutting is mostly utilized for the cutting of such hard materials due to its tremendous machining outcomes. Here an attempt is made to cut the previously developed sample of hybrid metal matrix composite A359/B4C/Al2O3 by abrasive waterjet machining process. Three different samples with change proportions of reinforcement from 2% to 4% were used in this study to create the flat machined surfaces. The surface roughness profile and 3D surface detailing are generated through the microprof FRT machine and inbuilt measuring sensor. Result revels that rough cutting with the average surface roughness value ranges from 7 to 9 µm for the selected samples. The machined surface is full of cutting traces with some of macro pores of size 1.2 mm to 1.8 mm observed by 3D profile views.
