Welcome to PRESM 2025 Welcome to PRESM 2025 On behalf of the committee members of PRESM 2025 and the Korean Society for Precision Engineering (KSPE), we extend our heartfelt gratitude to all guest speakers, session organizers, co-organizing societies, and governmental supporters for their invaluable contributions to PRESM 2025. The conference will take place from July 7 to July 12, 2025, in Chiang Mai, Thailand. Since its inception in 2011, PRESM has been committed to advancing precision engineering and sustainable manufacturing for the benefit of global society. Recently, KSPE announced a new vision: "Precision Engineering for a Sustainable and Prosperous Life, Forever," emphasizing smart and green technologies. Artificial Intelligence (AI) has become a key driver of innovation in precision engineering and manufacturing. The growing demand for AI computing has also heightened the importance of energy and environmental research. Additionally, robotics is revolutionizing industries and shaping the future of mass production. In light of these emerging trends, PRESM 2025 will highlight cutting-edge developments in AI, robotics, and sustainability. This year, our goal is to foster in-depth discussions on the future of precision engineering and international collaborations, with a particular focus on smart and green technologies. We hope that PRESM 2025 will provide an engaging and meaningful academic platform for all participants. Finally, I sincerely thank all the distinguished speakers for their valuable time and expertise. Your participation is what makes PRESM 2025 a dynamic and impactful conference. We look forward to seeing you in Chiang Mai!   Chair of PRESM 2025 Prof. Sung-Hoon Ahn (Seoul National University, Korea) President, Korean Society for Precision Engineering
