Micro-structured surfaces possess excellent properties of friction, lubrication, drag reduction, antibacterial, and self-cleaning, which have been widely applied in optical, medical, national defense, aerospace fields, etc. Therefore, it is requisite to study the fabrication methods of micro-structures to improve the accuracy and enhance the performance of micro-structures. At present, there are plenty of studies focusing on the preparation of micro-structures; therefore, systematic review of the technologies and developing trend on the fabrication of micro-structures are needed. In present review, the fabrication methods of various micro-structures are compared and summarized. Specially, the characteristics and applications of ultra-precision machining (UPM) technology in the fabrication of micro-structures are mainly discussed. Additionally, the assistive technologies applied into UPM, such as fast tool servo (FTS) technology and slow tool servo (STS) technology to fabricate micro-structures with different characteristics are summarized. Finally, the principal characteristics and applications of fly cutting technology in manufacturing special micro-structures are presented. From the review, it is found that by combining different machining methods to prepare the base layer surface first and then fabricate the sublayer surface, the advantages of different machining technologies can be greatly exerted, which is of great significance for the preparation of multi-layer and multi-scale micro-structures. Furthermore, the combination of ultra-precision fly cutting and FTS/STS possess advantages in realizing complex micro-structures with high aspect ratio and high resolution. However, residual tool marks and material recovery are still the key factors affecting the form accuracy of machined micro-structures. This review provides advances in fabrication methods and assistive technologies of micro-structured surfaces, which serves as the guidance for both fabrication and application of multi-layer and multi-scale micro-structures.

“…Adding strategies into integrated product module creation Asan et al (2004) [34] Function-behavior-structure relevance System theory Design structure matrix (DSM) Nie (2013) [35] There are three kinds of modular rules: Function features, function and structure features, and function-behavior-structure relevance. The primary aspect supporting modularity at an earlier stage is the product's function features, and several methods have been developed to support the development process.…”

“…The product modularization process has been further refined. From the system theory perspective, the function-behavior-structure (FBS) model was proposed, in which the function features, behavior features, and structure features were all taken into account simultaneously [35]. The fundamental idea behind the FBS model is breaking down a function into sub-functions, concretizing the resulting abstract function into a specific behavior, and finally seeking a structural solution in order to carry out the behavior.…”

As a form of technological integration, metahuman has a significant influence on sustainable production because of its consistent technological evolution. However, few studies have provided insights into the technical assessment of metahuman by employing patents. In this paper, patent analysis is conducted to identify technological trends and the competitive situation in respect of metahuman from a product modularity perspective. First, we identify 17 highly relevant metahuman keywords by combining a literature analysis and an expert interview method and identify 42,256 patents from the Derwent Innovation Index (DII), thus improving the accuracy and validity of the data collection process. Then, metahuman product modularity is implemented using the function-behavior-structure (FBS) model, and seven technical topics are extracted from patents via latent Dirichlet allocation (LDA). Lastly, the procedure for identifying technology areas in respect of metahuman is improved by applying an optimized method to establish the connecting paths of product modules, technical topics, and patent data. The analysis results show that the development of metahuman technology can be divided into three periods. Different patent priority countries have distinctive competitive advantages and characteristics at the product module level. The findings of this study are intended to aid R&D enterprises and the government in formulating sustainable decision-making and promoting the development of the metahuman industry.

Freeform optics are widely used in many fields with its excellent optical performances. Fast tool servo (FTS) diamond turning technology are considered to be very promising technique for freeform surface fabrication. However, some elements may influence the machining accuracy, such as the spindle speed drift, periodical change cutting force, and diamond turning machine (DTM) motion errors. In this paper, an in situ measurement method and an error compensation machining technique are proposed to improve FTS technique machining accuracy. The machined surface profile data is obtained by a linear variable differential transformer (LVDT) and the error compensation machine is implemented by a two degree of freedom (DOF) FTS. The experiment results show that the form error is dropped by 20 % and surface roughness of 18.1 %. This technology is easy to take out that contributes to the application of high precision freeform surfaces in aerospace, military, biochemical medical, communication, and many other fields.
