“…Laser surface treatment modifies the properties of metal surfaces, enhancing wear and corrosion resistance, and therefore these applications have found widespread use in industries such as the aerospace, automotive, and medical industries [ 6 ]. The advancements in laser metal interactions have significantly improved manufacturing efficiency and opened new possibilities in the production of high-quality components [ 7 , 8 ]. Additive manufacturing (AM), also known as three-dimensional printing (3-D printing), has been used to make some products in many industries for decades [ 9 ].…”

In industrial manufacturing and research laboratories, precise machining of work materials is crucial to meet the demand for fast assembly and sustainable high-quality production. Precise machining procedures play a vital role in manufacturing compatible parts that meet the production requirements. This study investigates the impact of different parameters on burr formations and slot dimensions during the micro-milling of AISI 316 material. A careful examination was conducted using scanning electron microscopy (SEM) images under varying conditions. The variables considered include cutting speed, feed rate, and depth of cut. The main finding revealed that the feed rate and depth of cut significantly influence burr formation, with lower rates and depths resulting in noticeable reductions. A higher feed rate was associated with more pronounced burr formation. Moreover, burr widths on the down-milling sides were typically wider than those on the up-milling sides due to continuous chip formation and compressive forces during down-milling. Utilizing image processing, the study further quantified burr and slot widths with high accuracy, offering a reliable method to characterize burr formation. This research presents potential ways to minimize burr formation during micro-milling processes by effectively managing machining parameters.

“…But manual de-icing is low efficiency and high cost ( Cheng et al, 2022 ; Patel et al, 2022 ). In the past decade, inspired by nature, significant progress in de-icing/anti-icing has been developed ( Yi et al, 2021 ; Jiao et al, 2023 ). For example, inspired by the superhydrophobic properties of lotus leaves, researchers have successfully prepared superhydrophobic surfaces for anti-icing ( Han et al, 2020b ; Chen et al, 2022 ).…”

In this paper, a laser superdiffraction optical needle direct writing lithography method for single‐exposure fabrication of high‐aspect‐ratio microstructures (HARMs) is proposed. The principles of 3/4 circular image focusing and lithography exposure are theoretically analyzed, and the experimental setup is built. Experiments show that the linear interval and focusing accuracy of this method can reach 60 and 0.1 µm, respectively. Compared with the circular image focusing method, this method can determine the direction of defocus through the opening direction of the 3/4 circular spot. In addition, an optical needle with a resolution of 0.308 µm, a depth of focus of 1.836 µm, and an aspect ratio of 5.9538 is achieved by tightly focusing a radially polarized beam modulated by an annular amplitude type modulator with an annular factor of 0.7. Using this optical needle as the direct writing head, the HARM with a line width of 0.22 µm, a depth of 1.76 µm, and an aspect ratio of 8 is obtained experimentally by adjusting the photolithographic process parameters in combination with the focus detection curve. This method has the advantages of high fabrication efficiency, super diffraction resolution and high‐aspect‐ratio, which provides a new research idea for the fabrication of HARMs.
