Design and Development of TDOF System with PD Controller for Turning Operation
Keywords:Self-Excited Vibration, Chatter, Control System, Transfer Function
AbstractActive vibration control technique is very important for increasing life of various components and structures; this results in lower fatigue, better accuracy, and low maintenance. In the turning operation, chatter or vibration is a frequent problem, which affects the result of the machining and in particular the surface finish. Tool life is also influenced by vibration. The objective is to design and develop a two degree of freedom (TDOF) system with Proportional-Derivative (PD) controller for turning operation to reduce regenerative chatter with the aim of improving productivity, quality of surface finish, tool life and reducing environmental noise caused by chatter. A system consisting of a workpiece subsystem (workpiece with end supports represented by mass, stiffness, damping coefficient) and a cutting tool subsystem (tool with its supports represented by mass, stiffness and the damping coefficient). A Mechatronic system has been proposed and developed for reducing tool vibration in lathe tool during machining. It consists of electrical and mechanical components; the PD controller is designed to control the chatter that occurs between the tool and the workpiece. A Piezo actuator and sensor was embedded into the tool holder. The PD controller is used to send a feedback to the actuator. The PD controller is to be designed so that it suppresses the settling time and dampens the tool. The effective cutting stiffness and effective cutting damping are modeled as a spring and damper during machining. The original response of the system is modeled using transfer function method. Their output responses were obtained using Mat lab software.
