With the rapid development of processing technology, increasing processing efficiency is no longer the only goal but also the utilization of green and clean manufacturing procedures is required. In this context, the development of an efficient processing strategy for ceramic matrix composites (CMCs) is of great importance. Although SiCf/SiC composites are regarded as one of the most novel fiber-reinforced ceramic matrix composites, their processing is quite difficult. Along these lines, in this work, the orthogonal test of single-grain scratches was conducted under different lubrication modes. From the acquired results, it was demonstrated that compared with the dry type, the minimum quantity lubrication (vegetable oil) lubrication method exhibited the best effect, the scratch force was reduced by 48.3%, and the surface uplift height was reduced by 48.4%. The dominant mode of material removal of the SiCf/SiC composites was a brittle fracture, and the damage characteristics mainly included natural fiber fracture, matrix breakage, fiber pullout, and fiber exposure. In addition, the scratch depth and the scratch angle are the key factors affecting the processing quality. Increasing the processing ratio of 0° and using MQL (vegetable oil) have yielded the best results.

Qu et al (2022) investigated the grinding performance of ceramic matrix composites using mono carbon nanofluid minimum quantity lubrication (CN-MQL) with carbon concentration (C) = 5 g/L and noticed lesser normal grinding force ( F n = 20.3 N) and a reduction in surface maximum height difference ( S z = 4.13 μm) under CN-MQL compared to 44.9 N and 8.44 μm for dry grinding conditions, respectively.

Purpose Because many cutting fluids contain hazardous chemical constituents, industries and researchers are looking for alternative methods to reduce the consumption of cutting fluids in machining operations due to growing awareness of ecological and health issues, government strict environmental regulations and economic pressures. Therefore, the purpose of this study is to raise awareness of the minimum quantity lubrication (MQL) technique as a potential substitute for environmental restricted wet (flooded) machining situations. Design/methodology/approach The methodology adopted for conducting a review in this study includes four sections: establishment of MQL technique and review of MQL machining performance comparison with dry and wet (flooded) environments; analysis of the past literature to examine MQL turning performance under mono nanofluids (M-NF); MQL turning performance evaluation under hybrid nanofluids (H-NF); and MQL milling, drilling and grinding performance assessment under M-NF and H-NF. Findings From the extensive review, it has been found that MQL results in lower cutting zone temperature, reduction in cutting forces, enhanced tool life and better machined surface quality compared to dry and wet cutting conditions. Also, MQL under H-NF discloses notably improved tribo-performance due to the synergistic effect caused by the physical encapsulation of spherical nanoparticles between the nanosheets of lamellar structured nanoparticles when compared with M-NF. The findings of this study recommend that MQL with nanofluids can replace dry and flood lubrication conditions for superior machining performance. Practical implications Machining under the MQL regime provides a dry, clean, healthy and pollution-free working area, thereby resulting the machining of materials green and environmentally friendly. Originality/value This paper describes the suitability of MQL for different machining operations using M-NF and H-NF.

Understanding the complex interactions between the work material and abrasives is a difficult and hot topic during grinding of Gallium nitride (GaN) single crystals. In this work, molecular dynamics (MD) simulations of double-grits interacted grinding of GaN crystals were performed, and the grinding force, coefficient of friction, stress distribution, plastic damage behaviors, and abrasive damage were systematically investigated. The results demonstrated that interacted distance with both radial and transverse directions achieved better grinding quality than that with only one direction or single-grit grinding. The grinding force, grinding induced stress, subsurface damage depth, and abrasive wear increases as the transverse interacted distance increases. However, the influence laws of the interacted distance on atom number of phase transition and dislocation length are not distinct. Appropriate interacted distances between abrasives can decrease grinding force, coefficient of friction, grinding induced stress, subsurface damage depth, and abrasive wear during the grinding process. Grinding test combined with the cross-sectional TEM detection verified the reliability of the simulated damage behaviors, i.e. amorphous, high-pressure phase transition, dislocations, stacking faults, and lattice distortions. The results not only enhance the understanding of damage accumulation and material removal caused by the coupling actions of abrasives in grinding process, but also provide a feasible approach for the wheel design of ordered abrasives.
