Research Projects

Machine tool performance is fundamentally limited by process-induced vibrations. To avoid vibration induced instabilities, machines are operated conservatively, resulting in their underutilization. To fully harness a machine's potential, this project will monitor and improve machine tool operational performance using structure integrated sensors and actuators. A 100% improvement in performance characterized by higher material removal rates and better part surface quality is targeted. Real-time condition monitoring and system identification will detect vibrations and parameterize machine’s dynamics. Vibrations detected will be damped using active damping devices. Experimental characterization of machine performance with/without commercially available actuators will instruct the indigenization of new high-performance electro-magnetic/electro-hydraulic actuators. A hardware-in-the-loop simulator will be developed to test devices/solutions before their implementation on real machines in laboratory environments as well as at locations of our four machine tool industry partners. Integration of sensors and actuators with machines is expected to renew their performance and expand their functionality.
