3D Conceptual Design of Sheet Metal Products by Sketching

Design of sheet metal products can be a complex and elaborate process. However, many important aspects of the manufacturing characteristics of a product are already determined at the early stages of the design. This paper reports on a system for conceptual design of sheet metal products by sketching, based on principles of early incorporation of CAD, imprecise analysis, and natural, incontext i...

Optimization of Process Parameters in Sheet Metal Forming

Figure 1 shows a simplified CAD representation of the tools and initial blank in the stamping process. During stamping, the metal sheet is submitted to large displacements and large elasto-plastic strains; rupture and wrinkles must be avoided, (Figures 2 and 3). The resulting part must also satisfy quality requirements regarding its geometry: after tools removing, the springback effect (Figure ...

The Optimization of Servo Press Method for Sheet Metal Forming

Recently in the field of sheet metal forming, servo press, which can control the speed and position of the tool using a servo motor, is attractive method. Development process of servo press method is accelerated as the capacity of servo motor become bigger. In the future, it’s expected as a great alternative plan to replace conventional press method in order to improve quality, increase product...

Application of Six Sigma Robust Optimization in Sheet Metal Forming

Numerical simulation technology and optimization method have been applied in sheet metal forming process to improve design quality and shorten design cycle. While the existence of fluctuation in design variables or operation condition has great influence on the quality. In addition to that, iterative solution in numerical simulation and optimization usually take huge computational time or endur...
