At the beginning of my talk, I introduce National College of Technology and NITA. There are 55 National Colleges of Technology (NIT), which are called “KOSEN” in Japanese, throughout Japan. They were established in 1961, in response to a strong demand from the industrial sector to foster engineers. Each national college of technology provides five-year engineering education from 15 years old. 55000 students, which is 0.5% of population in every school year, enroll NIT. National institute of technology, Ariake College (Ariake Kosen) is one of the 55 National Colleges of Technology, and was founded in 1963. NITA where 1000 students is studying located in Omuta city, Fukuoka prefecture.

Then I introduce my research and development about abrasive technology. Currently I am trying to produce mat-surface by means of utilizing fixed abrasive. In common industrial techniques, mat-surface is produced by using chemical etching, electrical or laser abrasion, loose abrasive lapping, or shot blasting. These conventional processes, however, demand pre-masking of work-piece and relatively large scale back up facility. Thus, to fabricate mat-surface without pre-masking and large scale back up facility, utilization of fixed-abrasive tool is proposed. The method is experimented with new designed tool. The results of experiments prove that the developed tool is effective to produce mat-surface mechanically.


Kiyoshi Yanagihara received Dr. of Engineering from the University of Tokyo in 2006, and he became an associate professor of National College of Technology, Ariake College. Currently He became a professor of faculty of creative engineering from 2016. He is also a researcher of Prof. Tsuchiya laboratory, Institute of Industrial Science, University of Tokyo from 2016.

His major is mechanical engineering, especially he is teaching and researching on System Designing with Mechatronics, Measurement and Control, and Dynamics these days. He is a member of The Japan Society for Mechanical Engineer (JSME), Japan Society of Precision Engineering (JSPE), Society of Automotive engineers of Japan (JSAE), The Surface Finishing Society of Japan, and The Japan Association of National College.
