Abstract :
The electromechanical coupling phenomenon in CNC machine tool has an important influence on the dynamic precision of the feed system. The complicated dynamic characteristics and their evolutions with different parameters will aggravate the research difficulty of the electromechanical coupling mechanism. In this paper, taking SL250 lathe as the research object, the servo torque and mechanical structure are analyzed by Maxwell Tensor and Dale Bert principle. Three kinds of variation of dynamic characteristics are found as follows. 1) Dynamic characteristics vary with Space position; 2) Dynamic characteristics vary with Servo output characteristic; 3) Dynamic characteristics vary with characteristics of lathe bed. In addition, the mechanism and influence factors of the three types of dynamic characteristics are studied, respectively.
