Study on Technology of Noncircular NC Turning Based on Active Disturbance Rejection Control

Abstract:

In this paper, new technology of noncircular turning was presented, a voice coil motor-driven fasting tool servo system was established. A dual stage actuator mechanism was designed for the variable rake angle tool in noncircular turning process. The kinematics of mechanism was analyzed. An active disturbance rejection control technique was applied in mechanism control. The tool feeding and the workpiece rotation synchronized by using time-base method of PMAC and achieved the noncircular auto turning. The result shows that it can improve the precision and efficiency of noncircular turning based on active disturbance rejection control.
