“…It should be emphasized that both techniques still find their applications in the cutting of different materials. Namely, PWJ is commonly employed for machining weak materials such as foams and polymers or when foreign material contamination has to be avoided, but for cutting high-strength materials such as metal alloys or ceramics, the use of AWJ is necessary (Bergs et al, 2020).…”

“…Abrasive waterjet cutting heads, where the most feasible designs are able to introduce the abrasive slurry into the water jet with a minimal distortion of its hydrodynamic characteristics 3. Combined nozzle heads, such as dual-head or double-head systems, where up to four cutting heads can work simultaneously According to the system configuration, jet tools can also be categorized by their phase composition (Bergs et al, 2020):…”

“…Due to the nature of the erosion process, many experiments have found that particles with lower velocities tend to embed grit into the workpiece material [16,17]. On the other hand, researchers have reported that the embedded particles are fragments of the abrasive grit [18][19][20][21]. The study of Stachowiak and Stachowiak [22] revealed that the abrasive shape, rather than the abrasive hardness, plays a key role in the grit embedment.…”

Experimental Study on the Sustainability Assessment of AWJ Machining of Ti-6Al-4V Using Glass Beads Abrasive Particles

Abrasive Waterjet Machining (AWJM) is considered a viable alternative to conventional machining processes, due to its capability of rendering even complex features on parts with high productivity. However, it is currently also important for manufacturing processes to comply with the various aspects of sustainability, by putting emphasis on the environmental dimension apart from the economic. Although AWJM generally is considered an inherently environmentally friendly process, it is required that thorough experimental studies be carried out to evaluate the sustainability of AWJM under various conditions. In the present work, AWJM experiments under various conditions were conducted on a Ti-6Al-4V workpiece in order to determine the optimal conditions leading to a high degree of sustainability in this process based on several indicators. The experiments were carried out using glass beads, which act as an eco-friendly abrasive. After the basic outcome of the experiment was analyzed to determine the correlations between process parameters and depth of penetration, kerf width, and kerf taper angle, sustainability analysis with the aid of Grey Relational Analysis (GRA) was conducted. The optimum solution provided a sufficiently high score regarding both the economic and environmental dimensions of sustainability.

The peak value and pulsation amplitude of the self-excited oscillating pulse cavitation jet nozzle are essential indices to evaluate the jet performance. We established a simulation model of the jet process of the nozzle to investigate the evolution mechanism of the inner and outer flow fields. We used the chamber fillet, chamber diameter, chamber length, and outlet-tube diameter as the design variables, and the peak value of the striking force and the amplitude of the pulsation of the striking force as the target variables. The collaborative optimization design method of the nozzle was determined by combining the orthogonal test method, the back propagation neural network, and the nondominated sorting genetic algorithm. As indicated by the results, when the inlet pressure was 3 MPa, the factors ranked as follows in terms of their effects on the jet performance of the nozzle: the chamber fillet, the outlet-tube diameter, chamber diameter, and the chamber length. To verify the feasibility of the collaborative optimization method, the nozzle was fabricated via 3D printing, and the simulation model was verified by testing. This study provides support to the development of design theory for self-oscillating pulsed cavitation jet nozzles.
