Dr. Benny C.F. Cheung and Prof. W.B. Lee from the Department of Industrial and Systems Engineering (ISE) received the Natural Science Award (Second Class) in the Ministry of Education Awards 2010 at the Chinese University of Hong Kong on 1st March 2011. This award was given in recognition of their remarkable achievement in the modeling and characterization of nano-surface generation in ultra-precision machining. Ultra-precision machining based on single-point diamond turning (SPDT) is an indispensable technology in the manufacture of high-precision components used in different high-tech industries, such as advanced optics, telecommunications, and the biomedical and aerospace industries. The awardees’ research, undertaken in the Partner State Key Laboratory of Ultra-precision Machining Technology, has led to the development of a number of novel surface topography models and a surface characterization method that not only allows a better understanding of the theory of surface generation mechanisms at the nano scale in ultra-precision diamond turning of supermirror surfaces, but also makes the cutting process more predictable and cost-effective.
