In most of the sheet forming processes, production of the parts with minimum thickness variation and low required force is important. In this research, minimization of the sheet thinning and forming force in the hydraulic deep drawing process has been studied. Firstly, the process is simulated using the finite element method (FEM) and simulation model is verified using the experimental results....

Drawing of square section rod from round bar can be done with two die shapes. In the first die shape, deformation starts from corners of the square and in second die shape, deformation starts from sides of square. This article has compared the drawing force for both die shapes and as a result optimum die shape was determined. Due to complexity of metal flow inside the die, analyzing of actual p...

Drawbeads are applied in the deep drawing process to improve the control of the material flow during the forming operation. These drawbeads can be replaced by an equivalent drawbead in simulations of the deep drawing process. In this paper the implementation of an equivalent drawbead model in a finite element code is described. This equivalent drawbead takes not only the drawbead restraining fo...

How are art works created by artists? In this study, we focused on the drawing processes of a Chinese ink painter through a field study and a field experiment. In the field study, we observed processes of fusuma drawing in a temple, and in the field experiment, we asked the painter to draw sixteen pictures (eight drawings in BLANK condition and eight drawings LINES condition). We analyzed those...

Metal forming processes, compared with machining ones, reduce production steps and increase manufacturing speed in addition to saving raw material. In this paper, forming process of column of a steering mechanism is investigated by finite element analyses and experimental tests; and optimum die design parameters are found. Forming process parameters including die opening angle, bearing length, ...
