...Koetsu Yamazaki; Jing Han; Takayasu Otsuka; Takashi Hasegawa; Sadao Nishiyama This paper proposes a new tooling system and performs an optimum design on it to minimize the amount of thinning during a forming process of aluminum beverage can end shells. Numerical simulations of the shell forming...

... engineering forming processes sheet metal processing Lamina emergent mechanisms are mechanical devices fabricated from planar materials (lamina) with motion that emerges out of the fabrication plane (see Fig. 1 ) ( 1 2 ). LEMs achieve all or part of their motion through the deflection of members...

... innovations have shown that forming can also be made flexible, by new process configurations typically using simpler and smaller tools with increased (and controllable) freedom of motion. In order to facilitate development of such flexible forming processes, this paper examines the possibility that all...

... of this study is to design, for Stevenson-mechanisms, a general input speed trajectory and useful geometric properties that lead to desired ram motion for cutting and forming processes. In the past years, Tesar and Matthew 2 derived the motion equations of the follower by considering the variable speed...
