Electromagnetic Rotary Tables for Mill and Drill Machining
Authors: , ,
Abstract: The following paper shows the control and the practical use of magnetic bearings as rotary tables for mill and drill machining of heavy workpieces. In contrast to conventional rotary tables, magnetic bearings have certain advantages, which can only be used, if a stable and exact position control in five degrees of freedom is implemented. The main focus of this paper is on the cascade control with optimal disturbance rejection, sliding mode control and the decoupling of degrees of freedom.
