Professor Eiji Shamoto obtained his Bachelor (1984), Master (1986) and Ph.D. (1989) degrees from Nagoya University, Japan. He worked in Kobe University, Japan, as a research associate from 1989 and became an associate professor in Kobe University (1994). During his career in Kobe, he has stayed in Canada as a visiting researcher for one year (1995-1996), working in University of British Columbia. Professor Shamoto has been working in Nagoya University as a professor since 2002. His research interest includes material removal processes, machine tool dynamics and control, actuators and precision machine elements. He has authored and/or co-authored more than 100 archival journal articles and has given over 200 invited presentations and seminars at various conferences, industries, foundations and universities. He has published more than 10 book chapters and received more than 20 patents. Many of the invented and developed technologies have been utilized in Industry, e.g. "Elliptical Vibration Cutting" is widely utilized for ultraprecision/micro die/mold machining, and "Speed-Differing Multi-Milling" is recently utilized for mass production of precision steel plates.
Professor Shamoto has graduated more than 50 PhD and M.S. students, currently serving as the chairman of 6 Ph.D. and 4 M.S. students. He has chaired, co-chaired and/or organized over 30 sessions at international conferences and served as the chairman of the 3rd CIRP Conference on Process Machine Interactions (PMI 2012) in Nagoya, Japan. He is a fellow of CIRP and JSME. He has received numerous awards for his research. The recent notable awards that he has received are: i) 2014 The 3rd International Conference on Virtual Machining Process Technology, Outstanding Paper Award, ii) 2013 The Japan Society for Precision Engineering, JSPE Best Paper Award, and iii) 2012 The Japan Society of Mechanical Engineers, JSME Medal for Outstanding Paper.
New machining and machine tool technologies, which have been developed in Ultraprecicion Engineering Laboratory of Nagoya University, are introduced, including "Elliptical Vibration Cutting", "Speed-Differing Multi-Milling", "Chip-Guiding Cutting", and "Analytical Method to Predict Contact Stiffness and Friction Damping". The elliptical vibration cutting technology has realized ultraprecision/micro machining of difficult-to-cut materials, and it is commercialized mainly for precision die/mold machining. The speed-differing multi-milling technology improves machining efficiency and accuracy significantly by suppressing regenerative chatter vibration in multi-milling with a flexible structure, and it is utilized for mass production of precision steel plates. The chip-guiding cutting technology has recently been proposed to avoid chip jamming, and it is expected that it will not only achieve the avoidance but also reduce cutting force/temperature by combining chip-pulling technology. The analytical method to predict contact stiffness and friction damping has just been developed, which will open up doors to achieve fully analytical prediction of dynamic behavior of machines as well as maximization of their damping capacities.
