birth and raising us to become useful people for society, going through many hardships to be able to get to this day, it's been a long road with many thorns and we must always keep in mind so that we don't depend on birth and upbringing On every step of life, it is impossible to have steady steps without the image of a guide Those are the people around us, always guiding us in the right direction In the process of studying at HCMUTE, thanks to the guidance of teachers, administrators, officials and friends in the school, they have always helped, outlined the right paths, equipped with additional knowledge fully helpful in a methodical and considerate way to be able to successfully complete the study process here Our team sends special thanks to Mr.Pham Son Minh and Mr.Le Ba Tan Who guided us wholeheartedly, helped us in the process of researching and completing the project, did not mind the time, but helped us to correct our mistakes and correct and give suggestions to be able to complete the project in a timely manner the best Our team would also like to thank Mr.Tran Minh The Uyen, who helped us complete the model and provided the equipment to be able to complete the experimental process Besides, our team also thanks Mr.Truong Thanh Cong, who provided the processing equipment, and gave advice to ensure safety and accuracy in operating and using the machine Not to mention the teachers in the faculty office, who created the best conditions for the team to complete the project Finally, I would like to send my best wishes to the teachers and staff in the school so that they can continue to train people who are successful in study and work, who are good citizens of the country and who are good characters the most beautiful to create a picture of the economic development of our country Student Performance Nguyen Phuc Nam Le Minh Tri Pham Thien Quang iv ABSTRACT FABRICATION OF DAMPING MODELS USING FERROFLUIDS APPLICATION FOR TURNING TOOL When machining metal, there are always small impacts with continuous frequency on the tool, causing the phenomenon of resonant waves that easily cause vibrations to the tool This inadvertently affects the substandard turning surface quality Besides, causing more blade wear, leading to more financial loss in work It is this that prompted us to investigate the direction of a ferrofluid damping for these turning tool Ferrofluid is a type of nanomaterial with superparamagnetic properties as well as fluid-normal behavior Damping is one of the earliest and most potential uses of ferromagnetic fluids It has many advantages over conventional dampers, including reliability, flexibility and simplicity This report presents the basic principles required for the design of fluid damper devices this ferrofluid damper model has a console beam set of 25 cases, ferrofluid concentrations and a turning tool to be compared and summarized The latest advances in ferromagnetic fluid-based vibrational energy measurement are briefly explained In addition, in this report, we have proposed a new ferromagnetic liquid vibration absorber and experiments have proved that it has a damping effect Final, future research issues and directions related to ferrofluid damping technology are presented… Student Performance v TABLE OF CONTENT PROJCET MISSION i DISCLAIMER iii ACKNOWLEDGEMENT iv ABSTRACT v
