Precision Engineering: Innovation on manufacturing artifacts
The age of mass-production of materialized products is over. Products should provide much more value in their life cycles. Precision engineering realizes high-quality functions onto a tiny machine. The talk introduces the history of precision engineering and forecasts the future trends in manufacturing.

Multi-disciplinary Research in Ultra-Precision Machining Technologies: From Optics, Environmental to Bi-Medical Applications
Precision engineering has moved up several orders of magnitude since the fifties from the diamond turning of silicon wafers to the fabrication of micro functional structure on a dimension of less than 100 nm. This is made possible by the advances in ultra-precision machining and its related technologies as manifested in the design and fabrication of various critical components which are used in a broad range of new applications in optical, environmental and bi-medical industry. More often than not, most of these innovative products emerge from the application of multi-technologies and are cross-disciplinary in nature. The successful combination of various technologies has accelerated the birth of many new precision and nanotechnology products in the market. Some examples of successful applications are demonstrated. These include the development of advanced secondary optics for energy saving in LED road lamps and the efficient collection of solar power, the replication of bionic structures to reduce drag reduction in high-efficiency heat exchanging copper tubes, and the ultra-precision free-from polishing of orthopedic implants. Further potential developments are also discussed.

Ultrafast Femtosecond Lasers for Ultraprecision Engineering
Emerging possibilities of exploiting ultrashort femtosecond lasers as new light sources for diverse fields of science and technology are first addressed. Then emphasis is focused on the recent development made in the particular field of optical time/frequency measurement using the frequency comb of a femtosecond laser as the precision frequency ruler stabilized to the standard atomic clock. This enhanced optical frequency measurement then enables the advance in length measurement, which is accomplished by constructing optical frequency generators providing any optical signals on demand for the advanced optical interferometry of absolute distance measurements. Finally, a new method of high harmonic generation using a femtosecond laser is discussed with the intention of extending the operating range of the frequency comb to the EUV and soft X-ray regime.

AFM-based nanomachining and nanomeasurement techniques
Rapid advancement of micro/nano technology, nano machining and nano measurement techniques are attracting more and more interests because of wider applications in many research fields. To date, AFM has already been employed as a novel nano machining approach rather than only a nano measurement instrument. This talk mainly discusses some works on AFM-based nano machining and nano measurement techniques carried out in Center for Precision Engineering, including the following parts: By using an AFM diamond tip and the static ploughing technique, three-dimensional micro/nano structures on the metal surface are fabricated. Also this technique is integrated with self assembly process and nano imprint technique. Moreover, integrating the AFM Dimension 3100 system and high accuracy air spindle, the tool nose radius of diamond tools and roundness and roughness of the micro ICF capsules are measured.
