Seminar – Smart Damping Strategyies for High Performance Machining – Dr. Jay Tu
February 10, 2017 @ 11:30 am
Title: Smart Damping Strategies for High Performance Machining
Speaker: Jay F. Tu, Professor, MAE, NCSU
This presentation focuses on the research work on machining conducted by Prof. Jay F. Tu during his scholarly reassignment in 2016 at University West, Sweden. Prof. Tu worked with researchers at a university research center, Production Technology West, along with several affiliated Swedish companies.
Machining systems are inherently low in damping, susceptible to forced or self-excited vibrations due to the interaction between the cutting tool and the workpiece. Critical cutting forces during machining are usually unknown and poorly controlled, which, coupled with the vibration problems, could lead to premature failures of cutting tools and machine components, as well as poor surface finish of the workpiece. Although damping is a critical technology, its advance and implementation has not been as broad and effective as other advances in machining technologies. In this talk, Prof. Tu will discuss various approaches to answer two scientific questions: Where and how effective damping could be strategically added to the machine tool structure so that High Performance Machining (HPM) can be achieved? HPM in this project is defined as the machining capability to mitigate forced and self-excited vibrations while achieving maximal possible material removal rate without subjecting machine components to the risk of overloading or chatter
Prof. Jay F. Tu received his Bachelor degree from National Taiwan University and his Ph.D. from University of Michigan, Ann Arbor. From 1992 to 2003, he taught at Purdue University. He joined MAE, NCSU in 2003. In 2016, he was invited to University West, Sweden for a one-year research appointment. Prof. Tu’s research areas mainly focus on modeling, monitoring, and precision enhancement of high performance manufacturing processes, including high speed machining and laser material processing. He is currently the Editor of High Speed Machining – Modern Manufacturing Technologies.
