Research on Compound Servo Drive Control of Heavy Loading Feed Table
This paper described a new compound servo drive structure and control method of heavy loading feeding table. Feed and location of table are controlled by ball screw through the Servo motor, who’s mainly responsibility is for the movement positioning accuracy of the feed table; Moreover, the table has added a set of servo-hydraulic cylinder driver assistance systems. The two systems are synchronized by the mutual control, the stress situation and wear of the ball screw servo feed with the heavy loading can be improved, thus the dynamic response characteristics and long-term positioning accuracy of the servo feed table can be improved ,addition to, the life of ball bearings and machine tools guide can be enhanced.
