“…Further studies reported that it was also effective in the cutting of other types of materials such as glass and ceramics [1,[24][25][26]. The 2D UVA cutting was proposed in the 1990s, expected that a 2D ultrasonic motion of a tooltip could further improve the process performance [27][28][29][30].…”

“…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.…”

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.

“…For these tests, the cutting tool was vibrated at a frequency of 17.8 kHz. In the previous studies, [13,14] a transition from a ductile cutting regime to a brittle one was observed at higher magnitudes of the depth of cut a p when ultrasonic vibration was superimposed on the movement of the cutting tool when machining intractable materials. This effect was used to demonstrate a large range of beneficial effects in the machining of difficult-to-machine materials [15][16][17][18] Drastic changes in the elasto-plastic behavior of the material were observed [19,20] along with changes in interfacial processes, in which dry static friction at the boundary between the tool and the work-piece transformed into dynamic viscous friction in the presence of ultrasonic vibration.…”

Metastable b-titanium alloys such as Ti 15V 3Al 3Cr 3Sn are of great technological interest thanks to their high fatigue strength-to-density ratio. However, their high hardness and poor machinability increase machining costs. Additionally, formation of undesirable long chips increases the machining time. To address those issues, a metastable b-titanium alloy (Ti 15V 3Al 3Cr 2Zr 0.9La) with enhanced machinability was developed to produce short chips even at low cutting speeds. A hybrid ultrasonically assisted machining technique, known to reduce cutting forces, was employed in this study. Cutting force components and surface quality of the finished work-pieces were analyzed for a range of cutting speeds in comparison with those for more traditional Ti 15V 3Al 3Cr 3Sn. The novel alloy demonstrated slightly improved machining characteristics at higher cutting speeds and is now ready for industrial applications.

“…Further, a machine tool post is designed for the operation. Many studies have proved -not only theoretically but also experimentally -that a vibrational tool can greatly reduce the cutting forces during cutting due to a considerable reduction of the friction between the workpiece and the cutting tool [6][7][8][9][10][11][12].…”

Tooling device design for vibration-assisted high speed shaping of PMMA

et al. 2010

PMMA optical components that are used as one of the most important parts of high precision equipments and machines are increasingly replacing the glass due to the various advantages of PMMA. Especially in Light Guide Panels, the PMMA sheet that is used in Liquid Crystal Displays plays an important role in scattering the incident light and requires very fine machining as the sheet is directly related to the optical characteristics of the panels. The High Speed End milling and High Speed Shaping processes that are widely adopted and applied to the precise machining of Light Incident Plane still have quality problems, such as cracks, breakages, poor waviness, and straightness. This paper presents the tooling device design for machining a Light Incident Plane through vibration-assisted High Speed Shaping for increasing the optical quality by minimizing the above-mentioned problems. The cutting tool and the tool post presented in this paper are designed by the authors to increase the magnitude of the cutting stroke by adopting the resonant frequency without weakening the stiffness and to reduce vibrations during even high speed feeding. The dynamic characteristics of the cutting tool and the tool post are evaluated through simulation and experiment as well. The results reveal very appropriate dynamic characteristics for vibration-assisted High Speed Shaping.
