Purpose: The main objective of the project is to reduce the vibration of the tool and to increase the accuracy of the component. The efficiency of the tool and precise machining can be increased by this project. Design/methodology/approach: In this project sensors and vibration exciter are used. Findings: In order to suppress the vibration, sensors are placed on top of the tool and vibration exciter is placed at the bottom of the tool. The sensors will sense the vibration of the tool and the vibration exciter will generate opposite vibration force to suppress the vibration of the tool. By doing this we can acquire good surface finish of the components. Practical implications: The better surface finishes, increased tool life are obtained as the result of online vibration suppression, this methodology provides the simple and flexible control of vibration over conventional complex methods and the system adopt itself for variation in process parameters more over it is economically feasible.
