Abstract
In this paper, an active vibration control system is developed for peripheral milling processes. In this system, the workpiece is driven by a specially designed active stage to control the relative vibration between the tool and workpiece during milling processes. The stage is modeled as a control plant, and the cutting vibrations are treated as disturbances to the system. Robust mixed sensitivity method is employed in feedback controller synthesis to achieve robust disturbance rejection and stabilization. Numerical simulations and cutting experiments are carried out to validate the effectiveness of the control system. Results indicate the relative vibration between the workpiece and tool, as well as the rough of surface finish decrease significantly in the case of milling processes with the presented controller.
