“…Various geometries and high surface quality can be achieved with the application of different micro-cutting processes to produce micro-components; these advantages are shown in Table 1 [19][20][21][22][23][24][25][26][27][28][29]. The machining principle of micro-cutting is similar to that of conventional macro-cutting, but new challenges, such as predictability, producibility, and productivity, must be resolved [30]. Moreover, microcutting exhibits several different characteristics because of significant reduction in size.…”

Device miniaturization is an emerging advanced technology in the 21st century. The miniaturization of devices in different fields requires production of micro-and nano-scale components. The features of these components range from the sub-micron to a few hundred microns with high tolerance to many engineering materials. These fields mainly include optics, electronics, medicine, bio-technology, communications, and avionics. This paper reviewed the recent advances in micro-and nano-machining technologies, including micro-cutting, micro-electrical-discharge machining, laser micro-machining, and focused ion beam machining. The four machining technologies were also compared in terms of machining efficiency, workpiece materials being machined, minimum feature size, maximum aspect ratio, and surface finish.

“…These are the mechanical structure, spindle and drive system, tooling and fixture system, control and sensor system, and measurement and inspection system. These sub-systems together with the machining mechanics dynamically interact and determine the machine tool's performance [4,5]. Traditionally, machine tool design, analysis, optimization and performance evaluation were performed on mechanical systems and control systems individually.…”

Abstract:Using computer models to predict the dynamic performance of ultraprecision machine tools can help manufacturers substantially reduce the lead time and cost of developing new machines. However the use of electronic drives on such machines is becoming widespread, the machine dynamic performance depends not only upon the mechanical structure and components but also the control system and electronic drives. Bench-top ultraprecision machine tools are highly desirable for micro manufacturing high-accuracy micro mechanical components. However the development is still at the nascent stage and hence lacks standardised guidelines. Part 2 of this two-series paper proposes an integrated approach which permits analysis and optimization of the entire machine dynamic performance at the early design stage.Based on the proposed approach the modelling and simulation process on a novel 5-axis bench-top ultraprecision micro milling machine tool -UltraMill is presented. The modelling and simulation cover the dynamics of the machine structure, moving components, control system and the machining process, and are used to predict the entire machine performance of two typical configurations.

“…3,4 Following the machining mechanics, the machining performance can thus be determined by the dynamically interaction between the structural characteristics of machine spindle tool system and the dynamics of the cutting process. 5,6 Based on this concept, different approaches were developed for machine manufacturer to follow to improve machine productivity and energy efficiency, including the new materials 7,8 and design methodologies. [9][10][11] Optimization criteria of the machine tool design have been carried out by incorporating the dynamics of machine tool with the consideration of machining stability in process.…”

Artificial granite material has been used for construction of the high-precision machine due to superior damping ability. However, its lower material stiffness also lessens the application in fabrication of the machine tool. The purpose of this study was therefore aimed to verify the structure performance of the machine tool reformed with artificial granite material, instead of the casting iron. To gain insight into the optimized configuration of the vertical columns and spindle head stock, the static and dynamic characteristics of the machine models with cast iron and granite composites were predicted for comparison. With this, evaluations of the machine with different design were made to examine the experimental measurements on the prototype machine. According to the simulation results and experimental measurements, the static stiffness of the machine tool reformed with granite material is comparable to the original casting machine, differed by 8% approximately. However, granite machine shows superior dynamic stiffness, about 0.5-1.3 times of the conventional casting machine. This study verifies the feasibility and effectiveness in fabrication of the machine tool with the artificial composite material and provides the improvements for further fabrications.
