Summary: The study proposes a high-efficiency and easy-operating method for fabricating wear-resistant superhydrophobic structure using SiCp/Al composite material and wire electrical discharge machining. Experimental results demonstrate that the maximum contact angle of 153.3 degrees can be achieved with specific dimensions of the semicircular groove texture, indicating excellent wear resistance of the structure. Additionally, a theoretical model for contact angle and a design criterion for semicircular groove texture in superhydrophobic structures are established.

Summary: Rectangular microgroove surfaces show anisotropy and can effectively control the movement of water droplets in both parallel and vertical directions. This property makes them promising for applications in droplet-oriented delivery and microfluidics. Micro-milling provides a convenient method to adjust the dimensions of microstructures, enabling the exploration of optimal micro-structural parameters.

Summary: This paper conducted a comparative experimental study on the surface roughness of the milling groove bottom surface for Zr-based bulk metallic glass. Various comparative tests were carried out on different processing materials, milling tools with different coatings and geometric parameters, and different processing conditions. The results showed that Zr-based bulk metallic glass has good milling machinability and can achieve low surface roughness values through the tested processing conditions and methods. This research provides an experimental basis for groove milling of Zr-based bulk metallic glass and serves as a strong test foundation for the manufacture of Zr-based bulk metallic glass parts.

Summary: Compared to nontraditional methods, the micro-milling process is highly flexible and widely used in manufacturing complex micro-parts. However, difficulties such as tool deflection, size effect, and tool wear limit its application. Laser-assisted machining (LAM) can play a significant role in reducing machining forces and enabling the use of higher feeds to overcome these challenges.

Summary: The difficulties in mechanical micro-machining, such as tool deflection, size effect, and tool wear, are more significant compared to mechanical macro-machining. However, mechanical micro-machining plays a crucial role in manufacturing complex micro-parts with high accuracy. Laser-Assisted Machining (LAM) shows promise in reducing cutting forces and increasing material removal rate (MRR) for difficult-to-cut materials. A model has been developed to examine how the structuring of parts before micro-milling affects uncut chip thickness. The results demonstrate that structured parts lead to reduced uncut chip thickness, with structure density being the most critical parameter.

Summary: This study investigates the influence of geometric errors and structural parameters of the machine tool on the dimple dimension and shape by establishing a geometric error model. It also builds a model to simulate the dimple geometry generated by ball-end milling. The experimental results show a good correspondence between the simulated and milled dimples, with a maximum error of 6.87%. The research identifies spindle attitude and axial feed rate as the main factors affecting the surface quality of micro dimples machined using micro ball-end milling with copying method, emphasizing the need for optimizing the feed rate to avoid deterioration of dimple surface and contour. This research is significant for fabricating micro-dimpled functional surfaces by surface texturing based on milling methods.
