“…In the UVA cutting, the high frequency electrical energy is converted into the mechanical vibrations via a piezoelectric/magnetostrictive transducer which is then transmitted through an energy focusing device [9,[13][14][15][16][17]. This causes the tool to vibrate along the cutting direction or the thrust direction at a high frequency (usually at a resonant frequency above 15 kHz) with an amplitude of 1-15 lm [4,8,9,13,18].…”

“…This causes the tool to vibrate along the cutting direction or the thrust direction at a high frequency (usually at a resonant frequency above 15 kHz) with an amplitude of 1-15 lm [4,8,9,13,18]. Based on the tooltip trajectories, UVA cutting can be divided into two main groups, i.e., the 1D UVA cutting of which the tool vibrates in the cutting direction or in the direction perpendicular to the cutting direction, and the 2D UVA cutting of which the tooltip vibrates simultaneously in both the cutting and thrust directions to form an elliptic trajectory.…”

“…A wide range of applications have shown that UVA machining is more effective compared with its conventional process, reflected by, e.g., lower machining forces, higher machining stability, less tool wear and better surface finish. UVA machining is particularly advantageous in the surfacing of difficult-to-cut materials [1][2][3][4][5][6][7][8][9][10][11][12][13]. As the mechanisms of the UVA processes (e.g., cutting, drilling and milling) can be better elucidated by the UVA cutting, our discussion in this paper will focus on the UVA cutting unless otherwise required.…”

“…Presently, both the 1D and 2D methods are used in cutting a wide range of materials and components with complex surface features [40][41][42][43]. The success of UVA cutting in these applications has also stimulated the investigations on difficult-to-cut materials, such as nickel-based alloys, tungsten carbides, silicon nitrides, metal matrix composites and fibre-reinforced composites [4,[11][12][13]44].…”

Ultrasonic vibration-assisted (UVA) machining is a process which makes use of a micro-scale high frequency vibration applied to a cutting tool to improve the material removal effectiveness. Its principle is to make the tool-workpiece interaction a microscopically non-monotonic process to facilitate chip separation and to reduce machining forces. It can also reduce the deformation zone in a workpiece under machining, thereby improving the surface integrity of a component machined. There are several types of UVA machining processes, differentiated by the directions of the vibrations introduced relative to the cutting direction. Applications of UVA machining to a wide range of workpiece materials have shown that the process can considerably improve machining performance. This paper aims to provide a comprehensive discussion and review about some key aspects of UVA machining such as cutting kinematics and dynamics, effect of workpiece materials and wear of cutting tools, involving a wide range of workpiece materials including metal alloys, ceramics, amorphous and composite materials. Some aspects for further investigation are also outlined at the end.

This paper aims to reveal the material removal mechanisms of the elliptical vibration cutting (EVC) and present the predicted model of orthogonal cutting force. Further study of mechanism will be helpful to explain the phenomena that EVC can reduce the cutting force, lower cutting temperature, and improve the surface integrity. In each overlapping EVC cycle, almost all the parameters are time-varying, of which two important factors are focused: (i) transient thickness of cut and (ii) transient shear angle. The analysis model simplified the complex process of the EVC as conventional cutting (CC) which considering two transient variables. This paper presents a non-equidistant shear zone model to predict the shear angle, tool-chip friction angle, and shear stress in CC under the same conditions of the EVC. Then, the transient thickness of cut and transient shear angle are investigated. Thus, an analytical model of the force in EVC is proposed. The model is available to predict the cutting force of the EVC accurately without any experimental parameters in CC. In addition, experimental results available in the literature are conducted for comparison, which are in well agreement with the analysis model

Finite Element Analysis of Mechanical Properties of 3D Surface‐Core Braided Composites

Three‐dimensional (3D) surface‐core braided composite is a new type of braided composite with a skin‐core structure. Three parameterized structure models of unit‐cell located in the interior, surface and corner regions are established. Under the general periodic boundary conditions, predictions of effective elastic properties and mechanical responses are presented by using the finite element method. The deformation and stress distribution of three unit‐cell models are demonstrated and the effects of braiding parameters on the mechanical properties are investigated in detail. Numerical results indicate that the three unit‐cells have distinctive properties and the effects of surface and corner regions on the mechanical properties of the whole material should be considered to obtain accurate results. Good agreement between the calculated results and available experimental data verifies the applicability of the proposed models. POLYM.
