| Seminar Title / 报告题目 | Measurement technologies for advanced manufacturing/ 面向先进制造的测量技术 |
| Seminar Abstract | A part or product is made from raw materials through a chain of manufacturing processes. For instance, in a mechanical manufacturing system, the process chain is a combination of manufacturing technologies such as casting, forming, milling, drilling, turning, grinding, polishing, chemical etching, and assembly. In a photolithography system for manufacturing electronic computer chips, the process chain typically starts from crystal growth of silicon ingot, followed by ingot slicing, wafer chemical mechanical polishing, material deposition, photoresist coating, exposure, developing and baking, etching and ion implantation, ashing, chip separation and packaging. For any type of manufacturing systems, measurement is an essential operation to cover the entire process chain. Measurement activities are not only applied to the final product for inspection purposes but also to each process for process control. In this talk, the major physical quantities in manufacturing are classified and categorized as measurands in integrated metrology. Fundamentals and implementation of the corresponding measuring instruments for each group of the physical quantities are then presented. |

| Seminar Title / 报告题目 | Advances in Ultra‑precision Machining Technology and Applications / 超精密加工技术前沿及应用 |
| Seminar Abstract | Ultra‑precision machining technologies are widely employed to achieve surface finishes at the nanometer scale and form accuracy within the sub‑micrometer range. These technologies find applications in fields including advanced optics, photonics, telecommunications, biomedicine, biomimetics, and aerospace. The surface quality and functional performance of workpieces are closely linked to the mechanisms of nanometric surface generation during the ultra‑precision machining process. Currently, achieving ultra‑mirror surface finishes and desired functional outcomes in many industrial applications still relies heavily on the experience of researchers and the skills of operators. However, our scientific understanding of nanometric surface generation in ultra‑precision machining remains incomplete. This presentation discusses the latest research on ultra‑precision machining and its nanometric surface generation mechanisms. It also explores the relationships among surface quality, functional performance, and nanometric surface generation for workpieces produced using various ultra‑precision machining technologies. The presentation aims to shed light on perspectives that could facilitate the expanded application of ultra‑precision machining technologies. |

| Seminar Title / 报告题目 | A Preliminary Exploration of Atomic‑Level Precision Manufacturing / 原子级精度制造初探 |
| Seminar Abstract | Short‑wavelength optical components, operating in the ultraviolet to X‑ray wavelength range, are core elements of major optical engineering projects such as photolithography, free‑electron lasers, and laser fusion systems. They demand atomic‑level precision and represent the cutting edge of optical manufacturing technology. This report focuses on photolithography objective lenses and X‑ray reflectors as typical processing targets. To overcome the challenge of suppressing atomic‑scale mid‑ and high‑frequency errors on optical surfaces, an innovative polishing method based on shear‑thickening elastic force confinement is proposed. The mechanism by which strong shear elastic force confinement regulates atomic migration is introduced. Leveraging the principle of material removal via elastic force, atomic‑level ultra‑smooth surfaces are generated. The high‑precision and efficient suppression of mid‑ and high‑frequency errors is achieved through shear‑thickening effects. On this basis, a combined processing technology for achieving atomic‑level accuracy on complex curved surfaces is proposed, and new equipment is developed, thereby laying a manufacturing foundation to meet demands for short‑wavelength optical components. |

| Seminar Title / 报告题目 | Direct Acoustic Manufacturing for Thermosetting Components: Theory and Key Technologies / 热固性材料零件的声直接制造理论与关键技术 |
| Seminar Abstract | This report proposes an original concept and method called "Direct Acoustic Manufacturing." It systematically investigates the mechanical, physical, and chemical synergistic mechanism between acoustic waves and thermosetting materials, and explores acoustic manufacturing of thermosetting and composite components. The acoustic manufacturing method overcomes the limitations of conventional methods, which rely on layer‑by‑layer printing and discrete energy input. Instead, it offers continuous control with full degrees of freedom, cross‑scale structures, multi‑material compatibility, and tunable properties. These features enable integrated manufacturing of complex components, combining design, fabrication, and property control. Breakthroughs have been made across multiple fronts, such as integrated forming of carbon fiber composites, high‑precision flexible sensor structures, and multilayer electronic composite materials. As a green, fast, and low‑cost solution, this innovative manufacturing technology opens new possibilities for cutting‑edge fields such as high‑end printed circuit boards, bioinspired functional materials, and metamaterials. It holds broad application prospects in aerospace, electronic manufacturing, medical devices, and beyond. |
