Abstract
With the application of single point diamond ultra-precision turning technology in optical free-form surface processing, the development of high-frequency large amplitude fast tool servo system has become a research hotspot. In this paper, a double piezoelectric ceramic fast tool servo system is designed. Its performance index is 60μm stroke at 300Hz. In this paper, the structural design principle and processing technology of the system are systematically analyzed. The stiffness analysis of the system were carried out by using the finite element analysis software to verify the performance of the high-frequency response amplitude of the system. In this paper, the key technology research on the structure design of double piezoelectric ceramic fast tool servo system provides the basis for improving the machining accuracy and efficiency of the fast tool servo system.
