Research achievements and impact

Scholarship – Bialystok University of Technology

As a part of the project titled: International scholarship exchange of doctoral students and academic staff (PROM) financed from the National Academic Exchange Agency (NAEA) program, Institute of Mechatronics Ph.D. student Paulius Karpavicius – performed an internship at Bialystok Technical Universities, Faculty of Mechanical Engineering.

Paulius Karpavicius in his doctoral thesis investigates the mechanical vibration energy harvesting system for monitoring of rotating tool condition during machining operation. During the two-weeks internship from June 24 to July 5, 2019 at the Faculty of Mechanical Engineering of the Bialystok University of Technology Paulius Karpavicius continued simulation research and experimental verification of the milling tool condition monitoring system under the supervision of dr. hab. eng. Arkadiusz Mystkowski from the Department of Automatic Control and Robotics.

The topic of the work is development of a self-powered rotating tool condition monitoring system. In this system, the electrical energy required to power the systems electronics is harvested from the mechanical vibration of the tool using piezoelectric transducer during machining operation. In particular, the harvested electrical energy is enough to power up the low-current Bluetooth module that provides a real-time transition of data concerning tool condition to a Bluetooth enabled smart device. The developed system is able to predict the wear of the cutting tool and to monitor other parameters of the CNC machine.  One of the example of the domestic application can be a cutting tool vibration monitoring during milling process, where the operator receives urgent data about the milling process parameters on a smartphone application.

In the system under development, the self-powered monitoring system with a piezoelectric transducer and a Bluetooth module is integrated in the milling knife holder. During the cutting process, a higher wear of the milling cutter generates a greater amplitude of vibrations and thus a higher electrical voltage is generated by deformation of the piezoelectric transducer.

The research conducted at the Faculty of Mechanical Engineering of the Bialystok University of Technology concerns the experimental verifications and measurement of the torsional and radial vibrations (in two axis) of the milling tool holder and the measurement of the vibration harvested energy. Tests were performed for various parameters of the machining process, including different wear modes of the milling cutter.

The combination of measurements results, their processing and analysis will allow us to obtain a machine tool vibration signal estimator using the piezoelectric transducer. Finally, the vibration estimator together with the piezoelectric transducer will provide the self-powered torsional/radial vibration sensor with wireless communication.

The research results will be published in journals from JCR database.
