英文摘要: Nano-structures and devices have unique advantages in the aspects of mechanical, physical and chemical properties, which have been successfully utilized in the fields of MEMS, sensing, communication, medical and daily life. Fabrication of nano-structures has been becoming the leading-edge research in precision engineering and nanotechnology. Aiming at the requirements of tip-based nanofabrication, this research will investigate the mechanical design optimization theory of 3D nano-structure controllable machining system. The reliable and accurate nano-fabrication principle and prototype technique will be firstly investigated, and then the kinematics and dynamics of the proposed mechanism will be developed. Further, the sensing, measurement and control methodologies of micro/nano- cutting force will be explored. Accordingly, a DSP-based control system will be established. Finally, the nano-fabrication techniques for improving machining accuracy and quality will be performed. This research not only establishes the key enabling techniques underpinning the fields of nanotechnology and further improves the nano-fabrication level of China, but also provides great potential applications in scientific and engineering areas.
