Special Issue Information

Dear Colleagues,

Ultra-precision machining is a multi-disciplinary research area and an important scope in advanced manufacturing technologies. Ultra-precision machining is a development upon conventional precision machining processes. Recently, achieving nanoscale features on products has become important in the manufacturing of critical components. Different engineering applications, including medical, dental, defense, aerospace, computer science, and electronic components, demand extreme smoothness and optical quality of the machined surfaces. One of the main objectives in advanced manufacturing of optics is to reach, ultimately, high precision in accuracy of optical surface generation. Different efforts have been undertaken to improve the machining conditions, as well as the outcome of the ultra-precision machining process in terms of surface finish and form accuracy. Advanced machining technologies, non-conventional machining techniques, and hybrid machining platforms are the state-of-the-art technologies recently used in ultra-precision machining.

This Special Issue seeks research papers on the recent advances and frontiers of ultra-precision machining. We call for papers in ultra-precision micromachining and nanofabrication that contribute to the advances of new principles, mechanisms, and methods. Original research papers, review articles, and short communications are all welcome.

Wetting hysteresis is the most important characteristic of microfluidic chips for modeling multiphase flows in rocks, including for oil production problems. Plasma modification of surface wetting characteristics is well studied, but there is a problem of stabilizing the resulting surface for use in a liquid hydrocarbon media. In this work, a simple and accessible technology for modifying the surface of PDMS and glass using a dielectric barrier discharge in a chamber based on the d’Arsonval apparatus has been developed. The surface wetting hysteresis for PDMS and glass was studied as a function of the plasma treatment time. It is shown that with the help of plasma treatment it is possible to change the wetting angles of the walls of microfluidic chips in a very wide range, thereby simulating the conditions of both hydrophobic and hydrophilic rocks. At the same time, PDMS has the widest possible range of changes in the wetting angle; the advancing contact angle decreases from 120° to 10°; receding contact angle—from 70° to 0° during plasma treatment. It has been shown that plasma treatment of a microfluidic chip, together with a 30 min primary extraction with oil and salt water, leads to a significant change in the wetting characteristics of its surface. This in total leads to an increase in the oil displacement efficiency from the chip by about 10%. In general, the results of the study showed that plasma surface treatment for the hydrophilization of microfluidic chips is a simple and affordable technology for controlling the wetting characteristics of microfluidic chips. PDMS in this case is a promising material. Full article

In precision engineering, the use of compliant mechanisms (CMs) in positioning devices has recently bloomed. However, during the course of their development, beginning from conceptual design through to the finished instrument based on a regular optimization process, many obstacles still need to be overcome, since the optimal solutions often lie on constrained boundaries or at the margin of safe/unsafe domains. Accordingly, if uncertainty occurs during the fabrication or operation of the mechanism, it might lose its functions, rendering the design infeasible. This paper proposes a universal design process for positioning CMs, consisting of two steps: optimal design of the pseudo-rigid-body model, and reliability-integrated multi-objective optimization design using NSGA-II algorithms. This optimization algorithm is applied in the design of a feed drive mechanism for micromachining. The optimal design is also fabricated and tested. The results calculated for the displacement amplification ratio, natural frequency, and input/output stiffness using different approaches, including analytical methods, simulations, and experiments, were compared to evaluate the efficiency of the proposed synthesis method, and show discrepancies of less than 5%. Thus, the results convincingly support the applicability of the proposed optimization algorithm for the design of other precision-positioning CMs prone to failure in vulnerable conditions.

Studies of surface topography including processes of measurement and data analysis have an influence on the description of machined parts with their tribological performance. Usually, surface roughness is analysed when a scale-limited (S-L) surface, excluding short (S-) and length (L-) components from the raw measured data, is defined. Errors in the precise definition of the S-L surface can cause the false estimation of detail properties, especially its tribological performance. Errors can arise when the surface contains some burnished details such as oil pockets, dimples, scratches, or, generally, deep or wide features. The validation of proposed methods for S-L surface definition can also affect the accuracy of the ISO 25178 surface topography parameter calculation. It was found that the application of commonly used procedures, available in commercial software (e.g., least-square fitted cylinder element or polynomial planes, regular or robust Gaussian regression, spline, median or fast Fourier transform filters) can be suitable for precise S-L surface definition. However, some additional analyses, based on power spectral densities, autocorrelation function, texture direction graphs, or spectral characterisation, are strongly required. The effect of the definition of the S-L surface on the values of the ISO 25178 parameters was also comprehensively studied. Some proposals of guidance on how to define an appropriate S-L surface with, respectively, an objective evaluation of surface roughness parameters, were also presented. Full article
