SMART CHATTER CONTROL AND SUPPRESSION SYSTEM FOR EFFICIENT MACHINING

SMART CHATTER CONTROL AND SUPPRESSION SYSTEM FOR EFFICIENT MACHINING

In today’s growing competitiveness in the manufacturing industry, the cost-efficient machining of complex components poses a great challenge for process planners. The cutting capability and, therefore, the process productivity, if often limited by chatter vibrations. This type of vibrations can present multiple origins, from low frequency structural chatter to high frequency local mode chatter. Therefore, the vibration control is essential to assure a good surface finish, preserve tool life and increase productivity. With this purpose, a vibration reduction tool has been developed. This smart tool controls and optimizes the process by continuously checking the cutting process stability and applying the most proper process stabilization technique based on a decision-making algorithm. The system is fully integrated in a multitask machine through a controller communicated with the machine CNC. The machine user can supervise the performance of the system and interact with it through a specific HMI. Experimental tests to validate the improvements achieved through this method are shown.
