Recent Investigations on Incremental Sheet Forming: From Fundamentals to Industrial Application Technologies: Jun Chen1; Zhidong Chang1; 1Shanghai Jiaotong University
Incremental sheet forming (ISF) is a promising flexible forming process in fabricating low-batch or customized sheet metal parts, and has potentials in reduced process lead time & cost, and increased formability. In the plenary talk, recent investigations on ISF fundamentals and the technologies for ISF industrial application will be presented, which cover loading path algorithms, forming tool development, surface roughness and forming load predictions, new variants of ISF, deformation mechanism of different ISF variants and several industrial application cases. Finally, an outlook about ISF will be made as well.
8:15 AM Keynote
Tube Forming and Fabricating Technologies for Contributing Society by Tackling Problems of Environment and Aging Population: Takashi Kuboki1; Atsushi Shirayori2; Masaaki Mizumura3; Noah Utsumi4; Yeong-Maw Hwang5; 1The University of Electro-Communications; 2Utsunomiya University; 3Nippon Steel Corporation; 4Saitama University; 5National Sun Yat-sen University
Technologies for forming and fabricating tubes have been contributing to the development of society, and should evolve and have great roles in the future societies, considering the environmental problems. Global warming is a critical problem and the average temperature in the world is still increasing. Tubes have advantages of high rigidity for a unit weight and could manufacture light-weight components for transport equipment. The technologies on tubes should contribute for solving these problems and realizing sustainable societies.This paper introduces the author's technologies and reviews others' recent technologies on tubes. The technologies include hydro and air forming, rotary forming, bending, micro forming and so on. These technologies are qualitatively evaluated in terms of conflicting characteristics, such as formability, strength, productivity, flexibility and miniaturization. Some technologies are emerging to improve some of the conflicting characteristics at the same time for realizing excellent performances of the formed products.
