Research Directions

With respect to the up-to-date global trend of ultra-precision machining technology development and the growing demand for precision manufacturing technology in the nation, the SKL-UPMT has defined the following research directions:

Micro and nano machining mechanics

To conduct basic research to investigate the cutting mechanics and micro/nano surface generation mechanisms of ultra-precision machining technology with machining accuracy at the sub-micrometre level and surface roughness at the nanometre level.

Advanced ultra-precision machining technologies and processes

To research new theories, new processes and new technologies in ultra-precision machining, and conduct process and technical analysis for new requirements and new challenges in scientific research and industrial development.

Freeform surface metrology

The success of ultra-precision machining technology relies heavily on the associated technologies for precision metrology and freeform surface measurement to validate the quality of the surfaces being machined with sub-micrometre form accuracy and surface finish in the nanometre range.

Equipment for ultra-precision machining

To research and develop ultra-precision machining equipment and accessories for specific machining tasks. Although a lot of progress has been made in ultra-precision machining technology, there are still many areas that require further enhancement in ultra-precision machining equipment.

Advanced optics manufacturing and its applications

To conduct interdisciplinary research to develop new applications and new precision manufacturing technology for advanced optics and functional surfaces based on ultra-precision machining technology.
