| Abstract: | This paper includes the background of the research on the micro-motion machine with high frequency and long travel, the structure and characteristics of the machine, design of the closed loop system with feedback characteristics and the NC turning system for the workpiece with noncircular cross section. The key problem of designing the micro-motion machine is to solve the contradiction between high frequency and long travel. This paper uses the structure of permanent magnet and moving winding to solve the contradiction successfully. Based on this micro-motion machine, the paper uses advanced control method to design the closed loop system with feedback characteristics and the NC turning system for the workpiece with noncircular cross section. This NC turning system has passed the experimental test of working for 72 hours without interrupt in a factory. Now it has turned into a commercial product. |
