“…The controlled rotational motion of the face disk (10) is limited by adjustable springs (5). A forced oscillation motion can be also obtained by a cam (6) or by mounting a longer arm (8), as shown in Figure 4, with an attached sliding weight, which should be set to such a position that a resonance with the machining force frequency occurs.…”

“…These materials include titanium alloys, unidirectional fibre reinforced composites, hardened die steel, and miniaturised components [2][3][4][5]. Different cases of vibratory (intermitted) cutting are based on the motion of the tool vibration relative to the feed direction (in the normal and cutting directions) and on the tooltip trajectory (ellipse) [2,[4][5][6][7][8]. Moreover, the depths of the cut are small (up to 0.5 mm) for small reciprocating tool movements, and up to 0.05 mm for an elliptical tool motion [7].…”

“…In this case, the vibrations are directly generated using a numerically controlled machine tool axis and NC program [2]. The researchers have shown that vibration-assisted cutting (machining) has several advantages including decreased cutting forces, increased tool life, high surface quality, and increased machinability [4,6,8,9,11,12].…”

This paper presents the design of a cutting tool‐holding device with controlled oscillations without an external energy source based on a varying machining force, and an experimental analysis involving the influence on the chip shape, tool‐wear, chip volume coefficient, and surface roughness. The design of the cutting tool‐holding device is based on reducing the dynamic stiffness by allowing one degree of freedom of the cutting tool, either translationally or rotationally. This paper analyses the advantages of such a design, and provides experimental measurement results presenting the advantages of the concept of a partially movable tool holder without an external energy source for application in other machining operations.

“…Precision turning can produce microstructures with a simple cross-section with a single repeated shape such as triangles or rectangles at higher speeds. In addition, more complicated cross-sectional shapes can be realized when the precision turning process is combined with additional devices such as a fast tool servo (FTS) and a slow tool servo (STS) [13,14,16,17].…”

A Study on the Deformation Behavior of a Microstructure Depending on Its Shape and the Cutting Section in the Precision Cutting of a Functional Part

The shape accuracy of microstructures is an important factor that directly affects the quality and performance of products. Nevertheless, it is difficult to find a study for the shape accuracy of microstructures below several microns. This study aimed to reduce the shape error in the precision machining of microstructures with a repeated triangular cross-sectional shape with a width of 5 µm or less. Two important factors in this study were the morphological features of the microstructure to be fabricated and the cross-sectional shape of the chip. The tool path was modified in consideration of these two factors. Before the tool path change, the shape error due to the deformation of the triangular micropattern in a DOC (depth of a cut) of 1 µm was about 0.39 µm. However, after the tool path was modified, the shape error due to deformation did not occur while maintaining the DOC at 1 µm.

“…A large number of reports have shown that EVC has advantages over many aspects, such as improving the machinability of materials, suppressing the cutting chatter, reducing cutting force, extending tool life and improving the surface uniformity (Jung et al, 2016;Zhou et al, 2016;Zhang et al, 2015Zhang et al, , 2016Li et al, 2015). To date, the studies on EVC are mainly focused on the following aspects: (1) EVC devices, (2) machinability of different materials, (3) EVC cutting force model, (4) tool wear condition.…”

Abstract. As always, the rapid wear of tools was one of the key factors limiting the precise turning of difficultto-machine materials with diamond tool. 3-D elliptical vibration cutting has inherited many advantages of elliptical vibration cutting, such as the intermittent cutting property and friction reverse property. However, studies on the tool wear of three-dimensional elliptical vibration cutting has not been reported yet. The formation principle of 3-D cutting elliptical trajectory was analysed and a prediction model of tool wear was established in the present work. Besides, a self-developed three-dimensional elliptical vibration device was employed to conduct turning experiment. Compared with the proposed model, the experimental results showed a great agreement with the proposed prediction model. This work may provide a reference for the further optimization of the 3-D elliptical vibration cutting parameters.
