PolyU researchers pioneer novel multi-energy field-assisted diamond cutting technology, enabling ultra-precision manufacturing for high-performance materials
The innovative and unique multi-energy field-assisted ultra-precision machining technology, known as in-situ laser-magnetic dual-field assisted diamond cutting (LMDFDC), has been developed by Prof. Sandy TO Suet, Professor of the PolyU Department of Industrial and Systems Engineering and Associate Director of the State Key Laboratory of Ultra-precision Machining Technology, and her research team. Relevant research findings are published in International Journal of Extreme Manufacturing.
Site field machining refers to the application of external energy fields, such as laser and magnetic fields, at the cutting site during the machining process. Existing field-assisting cutting techniques have certain limitations. For example, a laser field helps soften hard-brittle materials and makes them easier to cut, but often causes melting or craters due to overheating; a magnetic field can diminish cutting force and enhance heat dissipation to ease cutting process, but its effect is unstable across different materials and surface scratches caused by the exfoliation of hard particles in high-performance materials like high-entropy alloys (HEAs) cannot be avoided.
By combining laser and magnetic fields, LMDFDC synergises strengths of both fields and mitigates their respective drawbacks. The researchers compared this new approach with three other machining methods for HEA workpieces: laser-only, magnetic-only and cutting without any external field. Using a suite of advanced tools, they observed changes of the workpiece at multiple levels—from surface appearance to subsurface features and atomic-scale structures.
Results showed that, through thermo-magneto-mechanical multi-physical synergistic interactions, LMDFDC improves machinability to a degree not achievable with either field alone. In particular, the technology produces finished pieces with smoother surface and less damaged subsurface by using a magnetic field to enhance heat transfer and suppress laser-induced thermal damage, while the laser softens hard particles to avoid scratches and improve cutting stability. The dual-field coupling effect also prevents the formation of build-up on tool edges caused by severe friction, and rapid tool degradation from heat, significantly reducing tool wear and extending their lifespan.
In 2017, at the forefront of advanced manufacturing technology research, Prof. To led her team to propose the world’s first magnetic field-assisted diamond cutting technique that enhances manufacturability of difficult-to-machine materials. She said, “As time progresses, single-field assisted machining technologies are proving increasingly inadequate for the precision manufacturing of new high-performance materials, especially the emerging HEAs with their excellent strength and stability that are highly desirable for advanced engineering applications in high-ends fields like aerospace and energy. LMDFDC marks a technological breakthrough in machining these new materials, opening up new avenues of ultra-precision manufacturing technology.”
In addition to introducing a transformative dual-field assisted machining technology, the research also investigated what occurs, what changes and what improves in the materials when dual fields are applied. This deepens scientific understanding of material transformations during field-assisted processes and their underlying mechanisms, bridging a critical knowledge gap for designing future multi-field machining methods for various advanced materials.
“The research is among the first to thoroughly examine how laser and magnetic fields work together during ultra-precision machining, and how this combined action differs from using either field alone,” Prof. To added. “The significance of the findings resides in propelling frontier academic developments in multi-physics coupled manufacturing theories while discovering innovative machining approaches.
Currently in the process of patenting the innovative LMDFDC technology, the research team plans to explore additional combinations of energy fields to support the development of more versatile and reliable multi-physics machining approaches.
The research was supported by the National Natural Science Foundation of China’s General Program, as well as the General Research Fund of the Research Grants Council and the Mainland-Hong Kong Technology Cooperation Funding Scheme under the Innovation and Technology Fund of the Innovation and Technology Commission of the Hong Kong Special Administrative Region Government.

A Decade of Sharing the Flavors of China: ‘Chinese Restaurant’ Stays True to Its Mission Through Food and Culture
Over the past nine years, Chinese Restaurant has traveled across multiple countries and regions, including Thailand, France, Italy, and Hungary. Looking back on its journey of cultural exchange, the program launched a dedicated Chinese food truck in France, allowing local residents and visitors to conveniently experience authentic Chinese flavors. In Hungary, food served as a unique language that fostered deeper intercultural understanding. During the 50th anniversary of diplomatic relations between China and Italy, the program actively responded to the Belt and Road Initiative, using cultural interaction and culinary exchange to strengthen friendship between the two nations.
Now, standing at the threshold of its second decade, Chinese Restaurant: Nanyang Memories Season returns to Thailand, drawing upon the longstanding cultural, tourism, and people-to-people ties between China and Thailand. Through food and storytelling, the program once again brings Chinese culture to life on Southeast Asian soil.
The new season introduces an innovative business model inspired by traditional Chinese agricultural wisdom, creating a distinctive experience that combines pastoral ecology with the aesthetics of contemporary Chinese dining. New service concepts, including the “Chef’s Table” and “Chef at Home,” offer guests diverse culinary experiences while naturally integrating Chinese cuisine into everyday local life.
For ten years, Chinese Restaurant has remained committed to its original vision: telling authentic and heartfelt Chinese stories while showcasing the unique appeal of Chinese cuisine to global audiences. Through food, the program has helped narrow cultural distances, deepen international understanding, and highlight the confidence, vitality, and inclusiveness of Chinese culture.
The premiere episode of Chinese Restaurant: Nanyang Memories Season coincides with the Dragon Boat Festival, as the seven partners begin a brand-new entrepreneurial adventure in Chiang Mai, Thailand. From unexpected operational challenges and cultural differences to the dynamic interactions among team members with diverse personalities, the journey promises a wealth of memorable moments and compelling stories for viewers.
Over the years, the Chinese Restaurant franchise has consistently used authentic Chinese cuisine as a bridge connecting people across cultures. Every dish reflects the traditions and warmth of Chinese daily life, while every shared meal conveys the spirit and values of Eastern culture. Set against real-world international backdrops, the program vividly presents the depth and richness of Chinese civilization.
Today, Chinese Restaurant is far more than a culinary reality show. It has become a platform for cultural dialogue, mutual understanding, and friendship between China and the world. Through the universal language of food, the program continues to bring people closer together, allowing Chinese flavors and Chinese stories to resonate across borders and leave a lasting impression on audiences worldwide.
