Unfolding Method

The organized vertex coordination of the triangular surfaces is obtained by the meshing method in the 3D kernel based developing environment. To optimize the flattened form, the energy method is used to find the reasonable unfolding scheme, which seeks the solution to minimize the deforming energy generated when flattening the triangular surfaces. This algorithm is not the fastest one, but the versatile one especially for the non-developable surface with a large bending degree. With the unfolding method and the 3D kernel environment, the 3D unfolding system for the arbitrary surface satisfying the requirements is constructed.

Design Case

Most appearance and structure design has always been based on the product processing technology as the spindle, in general; sheet metal design changes in the appearance of the structure is based mainly on the basic structure of products and processing technology as the main core, and the appearance of manufacturing more Mechanical sheet metal, so most designers will use different design procedures to draw 3D graphics in the assembly or disassembly of parts, but different drawing procedures will affect the future assembly and disassembly of the design. In this study, we will compare two different models by building a model program using two different sheet metal structure drawings to present the problems that may be encountered in sheet metal design through a specific design flow. Through a real 3D drawing and design case, 3D graphics design flow, and finally through a design case to do a verification, to provide a reference for the future design.

In the today’s industry the sheet metal design plays a huge role, it has been said that almost the half of the designing is concentrating to sheet metals. But the lack of knowledge of the typical sheet metal aspects and basic rules of sheet metal designing, has led in to situation where more and more products are poor designed. This automatically leads to situation that the products are not manufacturing friendly. Designing time is shortening year after year, so the pressure to design the part as fast as possible is huge. Unfortunately all the design information and the design intent is processed and filtered to be fit for the Product Data Management (PDM) system. As the PDM was firstly designed to be used only for the storage base for the design drawings and other data; the feature-information and design intent is lost. This paper deals with two distinct yet interlinked themes. The first theme is the new requirements set for the new Product (Life-time) Information systems that can save the product information and design intent. And the second theme is the modern, light-weight and updatable product-services that allow the manufacturability to be ensured before product realization. With the help of novel product-service such as Design Manufacturing and Assembly (DFMA) for sheet metal industry designers will able to design in shorter time manufacture friendly sheet metal products.

Unfolding Method

The unfolding is the first step for the manufacturing of the sheet-metal part, which plays a major role for the accuracy and quality of the final product. Unfortunately, the inefficiency of the traditional drawing-based method made the process boring and sometime confusing. The CAD method made benefit for the designer. By means of the 3D modeling kernel and the mathematic model of unfolding process, the automatic design system of sheet-metal part was developed, in which the models are parametric and in 3D environment.
