Topic：Research in Ultra-precision Machining and Freeform Surface Measurement
Reporter：Prof. Benny Cheung
Time：9：00 am 19th August 2015
Location：the fifth western building A420（the first conference room）
Introduction ：Ultra-precision freeform surfaces are complex surfaces that possess non-rotational symmetry and are widely used in various industrial applications. Due to the geometrical complexity of the ultra-precision freeform surfaces, this imposes a lot of research challenges in the fabrication and measurement of those surfaces. In this presentation, the speaker would like to share his research work and experience related to ultra-precision machining and freeform surface measurement which has being undertaken in the Partner State Key Laboratory of Ultraprecision Machining Technology at The Hong Kong Polytechnic University. Some examples of applications of the technologies in freeform optics are also discussed.
