“…Ozkan et al [10] used TiAlN-and TiN-coated tools to mill carbon fiber-reinforced polymers and studied the influence of cutting on the surface roughness and applied force. Similarly, ultrasonic machining can be used to accurately cut composite materials such as ceramics, semiconductors, glass fibers, carbon fibers, and honeycomb materials [11]. Huang et al [12] applied fracture mechanics to introduce the dynamic stress intensity in the study of microscopic fracturing of honeycomb composites subjected to ultrasonic cutting.…”

Nylon (polyamide) is a typical composite base material, but its low hardness, poor rigidity, and low dimensional stability easily lead to burrs, fractures, curling, and other problems after nylon end faces are processed by conventional techniques. To prevent these problems, this article conducted experimental research comparing ultrasonic and conventional cutting of monofilament nylon and used the controlled variable method to analyze the micromorphology after cutting at different speeds and tensions. A novel ratio was also derived to characterize the topographic quality, and the feasibility and advantages of ultrasonic cutting of nylon were verified by evaluating the nylon surface quality under different cutting conditions. Test results showed layering on the rear face of nylon with ultrasonic cutting as well as a morphology quality directly proportional to the feed speed of the tool and inversely proportional to the tensile force exerted on the material. The end face of nylon after ultrasonic cutting provided a ratio 2.9% lower than that obtained from conventional cutting as well as a roughness reduction of 31.3%. Compared with conventional cutting, the end face was preserved, and no large-area breakage or edge curling occurred when using ultrasonic cutting. Moreover, a force analysis theoretically confirmed the advantages of ultrasonic cutting.

“…Its most important applications are found in the machine tool industry and the oil mining industry. In the machine tool industry, it is used to reduce the cutting force in all machining processes, including milling, turning, drilling and grinding [1][2][3][4][5][6][7][8][9][10][11]. In the oil drilling industry, it is used to reduce the friction force between the drill string and the borehole wall and to reduce the stick-slip motion [12][13][14][15][16][17][18][19][20].…”

The efficiency of reducing the friction force in sliding motion under the influence of forced vibrations of an elastic substrate significantly depends on the direction of these vibrations in relation to the sliding direction. This article presents a comparison of computational models developed by the authors to estimate the friction force in sliding motion under longitudinal and transverse tangential vibrations of the substrate. Fundamental differences between these models are discussed, and the results of comparative analyses of the impact of tangential vibrations on the friction force depending on their direction are presented. In the developed models describing the friction force, dynamic friction models of Dahl and Dupont and the so-called LuGre model were utilised. The analyses were performed as a function of the sliding velocity and two basic parameters of vibration, which are frequency f and amplitude u0. It has been shown that under longitudinal vibrations, the key parameter, which determines the occurrence of friction force reduction at a given driving velocity vd, is the amplitude va of vibration velocity. However, the level of this reduction cannot be determined unequivocally based on the value of this parameter alone since the identical value va can be obtained at different magnitudes of the frequency and amplitude of vibrations, and the reduction level is a nonlinear function of these parameters. The results of simulation analyses were verified experimentally.

“…The plastic flow of the hole wall surface metal is serious, which can cause scratches on the hole wall surface and mandrel fracture [6][7][8]. Liu et al [9] and Han et al [10], respectively, studied the effect of ultrasound on hole machining and micro-extrusion, and the results showed that the addition of ultrasound vibration reduced friction, improved surface roughness of the workpiece, and made the strengthening effect better. Mousavi et al [11] studied the ultrasonic extrusion process, and numerical simulation results showed that applying ultrasonic vibration during conventional extrusion can reduce the static pressure and yield stress of the material.…”

Small-hole structures, such as the millions of fastener holes found on aircraft, are typical stress-concentration structures prone to fatigue failure. To further improve the strengthening process of this small-hole structure, we make up for the limitations of laser shock processing (LSP) of small holes by combining it with the ultrasonic extrusion strengthening (UES) process to form a new strengthening method—laser shock and ultrasonic extrusion strengthening (LUE). The influence of the LUE process sequence and process parameters on residual stress distribution was studied through FEM, and the gain of fatigue life of specimens after LUE strengthening was also explored through tests. The results show that when using LUE technology, the friction force decreases with the increase in amplitude and decreases by 3.2% when the amplitude is maximum. The LUE process eliminates the thickness effect generated by LSP, which can achieve good stress distribution of small-hole components under smaller laser shock peak pressure, and reduces equipment power. LUE can significantly improve the fatigue life of small-hole components, and the maximum fatigue life gain can be up to 310.66%.
