# Advanced Manufacturing and Precision Machining
###### Abstract  
The field of advanced manufacturing represents a core technological domain vital for the evolution of modern manufacturing industries, acting as a critical driver for industrial transformation and the enhancement of international competitiveness. Building upon traditional manufacturing techniques, it deeply integrates interdisciplinary technologies such as electronic information, computer science, materials engineering, and intelligent control. By employing efficient, flexible, energy-saving, and environmentally friendly production methods, advanced manufacturing substantially improves the precision and efficiency of manufacturing systems. The rapid growth of this field not only reflects continuous innovation in manufacturing technologies but also signals major directions for the future development of the manufacturing industry. As a crucial component of advanced manufacturing, precision machining provides indispensable support for the production of critical components such as precision screws, gears, worm gears, guides, and bearings, which are extensively used in high-tech industries like aerospace [1, 2], medical devices [3, 4], and semiconductors [5, 6]. With machining precision ranging from 10 to 0.1 \(\upmu\)m and surface roughness below 0.1 \(\upmu\)m, advancements in precision machining technologies significantly enhance the manufacturing precision and efficiency of complex components. Furthermore, these advancements bolster the performance stability and service life of critical parts, offering essential technical support for the safe and efficient operation of major devices and equipment. The fields of advanced manufacturing and precision machining continue to face numerous challenges. On one hand, balancing manufacturing precision with efficiency remains a key technical hurdle. As demand for high-performance components grows, extreme manufacturing conditions, such as micro/nano machining and ultra-precision processing scenarios [7, 8], place new demands on process control technologies [9], error compensation techniques [10], and equipment performance. Simultaneously, global manufacturing is undergoing a rapid transition toward greener, smarter, and more sustainable practices. Within this context, advanced manufacturing and precision machining, as core technologies of the industry, shoulder the dual mission of driving manufacturing transformation. This includes improving resource utilization, reducing energy consumption and carbon emissions, and meeting the dual requirements of flexibility and precision in intelligent manufacturing. Achieving a digital and intelligent upgrade across the entire process--from design to production--requires not only the collaborative optimization of high-performance equipment and advanced processes [11, 12] but also the integration of key technologies, such as intelligent sensing, data-driven decision-making, and adaptive control [13, 14, 15]. As research in this field deepens, the developmental trajectory of advanced manufacturing and precision machining is becoming increasingly evident. This trajectory involves addressing current technological bottlenecks through interdisciplinary integration, theoretical innovation, and technological convergence [16], achieving efficient manufacturing processes driven by demand while satisfying the precision requirements of complex components [17], and establishing environmentally friendly and resource-efficientmanufacturing models with green manufacturing as the ultimate goal [18]. Research advancements in advanced manufacturing and precision machining will significantly drive technological progress in this domain, delivering substantial economic and social value to global manufacturing and providing critical support to meet complex industrial demands. In the future, the precision and efficiency of manufacturing will continue to advance, with higher-level application scenarios and innovative development models emerging through deeper integration with intelligent manufacturing systems.
