内容简介： 

Metal working processing has been attracted attention and developed as the most economical mass production technology. Metal microforming which scales down the conventional metal working processing with the excellent mechanical and functional properties of metal has been applied to biomedical, electronics and sensor fields with the miniaturization of products. However, in the metal microforming, not only the manufacturing process itself becomes difficult due to the difficulty in manufacturing the dies and tools and the handling of the material and the tooling, but also decrease in micro-formability due to the size effect of the material and the friction. Therefore, metal microforming is definitely a cutting-edge metal working technology which is far more difficult than conventional macroscale metal working technology. Liquid pressure medium is extremely useful as a flexible tool in metal microforming. Thus, if its ultrahigh pressure can be applied to a blank metal, a novel microforming process would be innovated. In this presentation, as one method to solve the above technological issues in microforming, a possibility of new microforming process utilizing ultrahigh pressure is discussed. We challenged to a new micro sheet/tube forming processes using its ultrahigh pressure. Results obtained through our challenges experimentally and numerically to date are shown, and then perspective of the ultrahigh pressure microforming process is discussed. 

报告人简介： 

 Ken-ichi Manabe was awarded his PhD in mechanical engineering in April 1985 from the Tokyo Metropolitan University (TMU), Japan. He had been a Professor at the TMU since 2002. After he retired from TMU in 2017, he received the title of Emeritus Professor from TMU. Prof. Manabe has undertaken extensive research on the theory and modelling of tube/sheet metal forming processes and intellectualization of their forming processes for over 45 years. Recently his research interest extends toward microforming technology and deformation mechanics in micro/meso scale. 

He was gained academic recognition in the Japan Society for Technology of Plasticity (JSTP), the Japan Society of Mechanical Engineers (JSME) and so on. He was the Vice President of the JSTP in 2011-2012, and the President of the JSTP in 2015-2016. He received the Best Paper Award in 1989, 2009 and 2012 from the JSTP. He received the JSTP Medal in 2010 and attained the grade of Fellow in 2009 from the JSTP. He held the first international conference on Tube Hydroforming (TUBEHYDRO) together with famous scholars from China, South Korea and China’s Taiwan, and served as a Conference chair in 1993. This conference is held every two years and has had a huge impact on the tube forming. 

He contributes to promote dissemination of tube forming technology and its theory and modeling as a chair (2004-2012) of the Tube Forming Research Committee of the JSTP. He has published 19 book chapters, over 210 refereed journal papers and over 210 refereed conference papers.
