On Line Monitoring of Micro End Tool Wear Based on One-dmensional Fractal 基于一维分形的微端刀磨损在线监测
Zhiqiang Wang, G. Zhang, Yifan Liu, Shuze Geng, Donghuang Shi, Zhenghao Yang
Based on the theoretical derivation of one-dimensional fractal, a new method to realize on-line tool wear monitoring of micro end tool is proposed. First, several different wear conditions of micro end tool are chosen as comparison samples, which includes the wear rate of micro end tool is 0, 10, 20, 30, $i$ and tipping respectively. The vibration signals of all samples are collected in time domain, and the range $k$ of each wear status is obtained based on one-dimensional fractal. Secondly, the vibration status of tested tool is monitored and analyzed, and its one-dimensional fractal is extracted. Finally, comparing the one-dimensional fractal of the tested tool with the fractal dimension range $j$ of the comparison samples, the status of tested tool is detected. In order to verify the above monitoring method, a small triaxial vertical testing machine is used. The results show that the one-dimensional fractal of each monitored micro end tool falls within the range of fractal dimension corresponding to actual wear.

A Novel Linear Edge Fitting Method with Short Edge Correction 一种新的短边校正线性边缘拟合方法
Fujun Wang, Xuteng Qin, Zhichen Huo, Dawei Zhang
In this paper, a novel linear fitting method for micro vision is proposed, which can be utilized to accurately estimate the pose of components in micro-assembly. After obtaining the edge information through Canny edge detection, an improved least square method is put forward to fit the linear edge of small components, where a threshold is utilized to reduce the influence of outliers in point set. In order to improve the estimation accuracy, the fitted linear edge is iteratively corrected through the information of detected broken lines. Compared with conventional linear edge fitting methods, the experimental results indicated that proposed method could effectively reduce the confidence interval of the fitted line, which would be helpful to improve the accuracy of pose estimation in micro-assembly.

Design of Precision Positioning Stage Driven by Voice Coil Motor with Integrated Active Eddy Current Damper 集成有源涡流阻尼器音圈电机驱动的精密定位级设计
Na Sang, Chi Zhang, Xiaolu Huang, Hongtao Yu, Weizhen Wang, Guilin Yang
A flexure-based precision positioning stage driven by voice coil motor (VCM) with integrated active eddy current damper (ECD) is proposed in this paper. This device is constituted of two identical VCMs, one ECD and one compound double parallelogram mechanism (CDPM). The VCM with Halbach permanent magnets (PMs) array is designed to yield a large driving force and low force ripple. The CDPM is selected as the flexure guide with the advantages of deterministic motion and high precision displacement transmission. The double-sided active ECD is proposed to suppress the residual vibration especially in the deceleration or stop motion process. Based on the analytical models and theoretical analyses of the VCM, the ECD and the flexure guide, the relationship between the input driving current and output displacement is obtained. Finite element analysis (FEA) is carried out to verify both the electromagnetic and dynamic performance of the designed stage. The results validate that the proposed stage can achieve a large motion range about $boldsymbol{pm 5text{mm}}$, deliver the force-constant variation less than 2%, and possess a high bandwidth approximately 55Hz.

Three-dimensional Laser-induced Hierarchical Copper Current Collector for High-performance Lithium Metal Batteries 用于高性能锂金属电池的三维激光诱导分层铜集流器
Bingyu Li, Jiaojiao Li, Zhen Yang, Minjuan Li, Yan Li, XuWei Guo, Faze Chen, Chengjuan Yang
Lithium metal, as the most ideal anode material for high energy density batteries, has high capacity and low electrochemical potential. However, the decrease in battery stability caused by the growth of Li dendrites during cycling, and the capacity drop caused by uneven Li plating both hinder the practical application of lithium metal as an anode material. Herein, we fabricate a copper current collector with 3D hierarchical structure by simple ultrafast laser processing method. The micron-scale groove structure can accommodate the volume change of lithium during the plating and stripping process, and reduce the local current density by increasing the specific surface area. Moreover, the laser-induced fluffy nano-CuxO provides more nucleation sites for Li, which uniformizes Li plating and reduces the formation of Li dendrites. Compared with commercial copper foils, half-cells based on 3D hierarchical copper current collectors achieve high coulombic efficiencies over 90% after 125 cycles at 0.5 mA/cm2, and a symmetric cell has a long cycle life over 800 hours at 0.5 mA/cm2. Therefore, our findings provide a feasible way to address the short-circuit problem and capacity decline caused by lithium dendrites in Li-ion batteries.
金属锂具有容量大、电化学电位低的特点,是高能量密度电池最理想的负极材料。然而,循环过程中锂枝晶生长导致的电池稳定性下降,以及锂镀层不均匀导致的容量下降,都阻碍了锂金属作为负极材料的实际应用。本文采用简单的超快激光加工方法制备了具有三维层次化结构的铜集流器。微米级的凹槽结构可以适应锂在电镀和剥离过程中的体积变化,并通过增加比表面积来降低局部电流密度。此外,激光诱导的蓬松状纳米cuxo为Li提供了更多的成核位点,使Li的镀层均匀化,减少了Li枝晶的形成。与商用铜箔相比,基于三维分层铜集流器的半电池在0.5 mA/cm2下循环125次后,库仑效率达到90%以上,对称电池在0.5 mA/cm2下的循环寿命超过800小时。因此,我们的研究结果为解决锂离子电池中锂枝晶引起的短路和容量下降问题提供了一种可行的方法。

Improvement of Corrosion Resistance of 7075 Aluminum Alloy by Micro Arc Oxidation after Hole Sealing Treatment 孔封后微弧氧化提高7075铝合金耐蚀性
Jian Li, Yiquan Li, Qianqian Cai
Aluminum alloys are widely used in aerospace and marine transportation industries because of their excellent properties. However, the aluminum oxide film on the surface of aluminum alloy in service is easy to be damaged by corrosive media, resulting in matrix corrosion cracking, which also hinders the wide application of aluminum alloy in more fields. In this paper, the PEO/SOT composite coating was prepared by plasma electrolytic oxidation (PEO) combined with surface oiling treatment (SOT). Oiling treatment can effectively cover the discharge channels and cracks on the PEO surface, so as to prevent corrosive ions from contacting through the coating and damaging the aluminum alloy matrix. The corrosion resistance of the composite coating was tested by electrochemical workstation. The results show that PEO/SOT composite coating has better corrosion resistance in corrosive environment than the substrate and PEO coating. This will help to expand the application of aluminum alloy in the field of higher requirements.
铝合金因其优异的性能而广泛应用于航空航天和海洋运输行业。然而,在使用中铝合金表面的氧化铝膜容易被腐蚀介质破坏,导致基体腐蚀开裂,这也阻碍了铝合金在更多领域的广泛应用。采用等离子体电解氧化(PEO)和表面上油处理(SOT)相结合的方法制备了PEO/SOT复合涂层。涂油处理可以有效地覆盖PEO表面的放电通道和裂纹,防止腐蚀性离子通过涂层接触而破坏铝合金基体。利用电化学工作站对复合涂层的耐蚀性进行了测试。结果表明,在腐蚀环境中,PEO/SOT复合涂层比基体和PEO涂层具有更好的耐腐蚀性。这将有助于扩大铝合金在更高要求领域的应用。

Design and Experiment on a Novel SMA Driven Micro-catheter for Active Navigation in Vascular Interventions 新型SMA驱动的血管介入主动导航微导管的设计与实验
Chengyang Li, Kecai Xie, Zhongjing Ren, Peng Yan
This paper presents a shape memory alloy (SMA) driven micro-catheter for active navigation in vascular interventions. SMA wires with microscale diameters and silicone rubber are employed for developing prototypes of such catheters. Selectively processed U shape SMA wires are biasedly embedded into silicone rubber to form the distal actuators with submillimeter diameters, which are characterized by infrared and CCD cameras. The transformation temperatures of SMA wires used for creation of distal actuator is proven to be approximately 35°C by the infrared imaging. The deflection angles of distal actuators are determined by the residual stress resulting from biased SMA wires and their shape memory effect. As a result, distal deflection within acute angles range is accomplished with actuators in submillimeter diameters. A micro-catheter (0.8 mm in diameter) with a distal actuator (0.5 mm in diameter) is mounted inside a vascular introducing sheath fixed on a 3D vascular model to experimentally validate the ability of proposed catheter for navigation.

Study of a 3D-printed Monolithic Compliant Tip-tilt-z Stage for Micro-alignment 用于微对准的3d打印单片柔性Tip-tilt-z平台研究
Huaxian Wei, Jian Yang, Yuanchao Li, Zhouwu Chen
Tip-tilt-z micro-positioning is crucial in wafer alignment. Due to the restrain of traditional manufacturing technique, it is hard to development compliant tip-tilt-z (CTTZ) mechanism in the form of single-piece monolithic structure. This paper presents the design, fabrication, and experimental tests of a CTTZ stage with monolithic spatial structure based on additive manufacturing (3D printing). The results verified the feasibility of developing complex compliant mechanism with spatial, compact, and monolithic structure, which could realize precision capability up to submicron and micro-radian using easy-access 3D-printing.
尖端-倾斜-z微定位是晶圆对准的关键。由于传统制造工艺的限制,很难研制出单片整体式的柔性tip-tilt-z机构。本文介绍了基于增材制造(3D打印)的整体空间结构CTTZ舞台的设计、制造和实验测试。研究结果验证了开发具有空间、紧凑和整体结构的复杂柔性机构的可行性,该机构可以实现亚微米和微弧度的精度。
