Research on Auxiliary Electromagnetic Damping System for Machine Tool Spindle

Abstract:

This paper studies auxiliary electromagnetic damping system in the conventional machine tools. Through the establishment of auxiliary active magnetic actuator array and the application of optimal control, dynamic control of additional stiffness and damping are achieved, so some active interventions can be applied to reduce the chatter of traditional machine tool spindle. Thus it causes to lower the radial vibration amplitude of the spindle at work and improve the machining accuracy. The experiments show that this system can reduce more than 88.06% spindle radial amplitude, and it can actually improve the precision to about1um, so the system has enormous potential for low-cost upgrade of traditional machine.
