| Abstract: | Micro-displacement technique is the important track to realize the ultra-precision machining. This paper introduces the method of realizing micro-displacement, and gives more introduction to the system of piezodectic ceramics micro-displacement mechanism. The system's working principle,structure,characteristics are showed. Finally, an experiment is done adopting piezodectic ceramics micro-displacement mechanism closed-loop controlling system controlled by MCS-51 single-chip computer to advanced workpiece's surface form precision. The result indicated that the workpiece's surface form precision advanced over 50%. |
