“…Many studies have been conducted on the grinding of this material (Liu et al, 2012;Cao et al, 2013;Zhang et al, 2016). Also, the grinding mechanism of the composite was studied from different fiber angles and different fiber orientations (Liu et al, 2017(Liu et al, , 2018Feng et al, 2017). In drilling, cemented carbide, high-speed steel, and other drilling tools are widely used as traditional tools (Wang et al, 2013;Xing et al, 2017); however, the drilling quality of carbon fiber reinforced ceramic matrix composites is very poor.…”

“…Due to the high hardness and brittleness of 2D C f /C-SiC composites, carbon fiber tearing and delamination can easily occur in drilling processes. With the wide application of diamond tools, diamond bits are becoming more and more popular (Ding et al, 2014;Feng et al, 2017). Thus, in this study, the feasibility of drilling such kinds of composite materials was investigated, where the self-made brazed diamond bit was used with different abrasive distributions.…”

Abstract. Drilling carbon fiber reinforced silicon carbide composites still forms a big challenge for machining because of their special braided structure and anisotropy. In this study, through the drilling of 2D Cf∕C–SiC composites, two kinds of brazed diamond core drills with different abrasive distributions were compared. The results showed that the drilling force and torque of the two drills decreased with the increase in the spindle speed and increased with the increase in the feed speed. Under the same drilling conditions, the drilling force and torque of the brazed diamond drill with the ordered abrasive distribution were far lower than those of the brazed diamond drill with the random abrasive distribution. Also, the quality of the holes drilled by the drill with the ordered abrasive distribution was better than that of the holes drilled by the drill with the random abrasive distribution, which is attributed to the uniform abrasive spacing provided by the drill with the ordered abrasive distribution.

“…Many scholars have recently adopted ultrasonic-assisted grinding (UAG) systems to process ceramic materials and found that introducing UAG can improve machining quality considerably. For instance, Ding et al [4] compared UAG with conventional grinding and found that UAG afforded less fiber fracture and 12% reduction in surface roughness. Moreover, Cao et al [5] designed an ultrasonic-assisted internal grinding (UAIG) technique for grinding SiC ceramics and compared it with the conventional internal grinding technique.…”

Ceramic grinding processing technology continues to advance rapidly. Recent studies are increasingly adopting ultrasonic-assisted grinding (UAG) for obtaining improved surface quality and reduced surface roughness. Because different grinding parameters could lead to different machining quality, operators may find it difficult to select grinding parameters on the basis of the expected machining quality alone. In this paper, an intelligent UAG system (IUAGS) that provides suitable grinding parameters for the operator is proposed. This IUAGS employs a proposed one-dimensional convolutional neuro-fuzzy network (1DCNFN) to establish a surface roughness prediction model, and then a particle swarm optimization algorithm is used to optimize the grinding parameters. The experimental results demonstrate that our proposed 1DCNFN has a lower mean absolute percentage error (MAPE) in surface roughness prediction than other methods do. Moreover, our IUAGS can provide appropriate UAG parameters on the basis of the specific requirements of the operator.

“…For composites grinding, 3D surface profile characterization was more comprehensive and scientific than traditional roughness characterization [19][20][21]. It was found that fiber orientation and grinding parameters were the significant influence factors of composites grinding, which had important effect on grinding force and surface quality [22][23][24].…”

Ceramic matrix composites have complex structures. For exploring the impact factors of machined surface quality and material removal mechanism, its internal structure must be decoupled, and then a unidirectional C/SiC composite was designed and fabricated in this paper. Through a series of representative surface grinding experiments, the machined surface of the composites was characterized by 3D profile test, and the microscopic characteristics and material removal mechanism of the grinding surface were discussed in detail. The results showed that the fiber orientation had a significant effect on the surface quality, and the order of 3D surface roughness was longitudinal > normal > transverse. On the basis of the systematic analysis of the microscopic characteristics of the machined surface, the brittle fracture was the dominant form of material removal in grinding process. Further, combined with 3D surface profile and surface micromorphology, the effect of fiber orientation on the removal mechanism of composites was revealed. The results not only enrich the machinability and improve the surface quality of unidirectional C/SiC composites, but also provide some guidance for grinding of the woven composites.
