| Summary, etc. | Rapid Product Development (RPD) becomes a crucial approach for the success of a company in a competitive market nowadays when the complexity and diversity of products keep increasing while their lifetimes are getting shorter and shorter. RPD requires collaborative effort from all parties in a chain from supplier to customer, especially marketer, product designer, process engineer a nd production engineer who directly involve, and design tools and techniques are necessary to ease the collaboration and to streamline RPD. Models are a good design tool that are helpful for gaining design information and insight as well as enhancing communication both within a product design and development (PDD) team and with others. Rapid prototyping (RP) has been introduced and become an important technology for RPD in which it cons tructs a physical prot otype rapidly without molds and dies. In the conventional RP process, 3D CAD models are translated into stacks of 2D contours which are used to generate machine commands to build the products layer by layer. In case that 3D model is not available, other channels for obtaining the product information are through reverse engineering (RE) from its physical part or its engineering drawing. Geometrical reconstruction (GR) is a proces s of reconstructing a 3D model from a 2D engineering drawing, and can be considered to be another technology, similar to RE, that enhances RP methodology by allowing a reconstructed model to be created quickly and ready for layered fabrication process. Therefore, a direct interface be tween GR and RP has been researched. Presented in this dissertation is an approach for direct interfacing GR and RP, called layer- based geometrical reconstructi on approach (LBGR), which seve ralactivities appearing on the conventional path will be bypasses. This approach has been developed to convert enrich information from 2D orthographic views drawing, commonly seen in the industry, to be a stack of contours which their information can be used to generate commands for constructing both physical model and virtual prototype (VP) layer by layer as well as to create a 3D solid model. With its main purpose for rapid prototyping, LBGR has been designed to acquire information on the drawin g locally in a top-down direction, and to allow fabrication process run in parallel to shorten fabrication time. In this approach, a stack of contours is created slab-by-slab. Rather than using the entire information from a drawing as pervious approaches of GR, drawing information is locally acquired to identify top and bottom contours of each slab before homotopy concept is applied to generate intermediate contours inside each slab. The thickness of slabs is varied depended upon their cross-sectional contours. The contours are identical inside a slab but different between slabs. A Pre-Contour Reconstruction table (PCR table) has been developed in this research as a tool for synthesizing the top and bottom contours for all slabs. Once the stack of contours is formed, these contours can be utilized for 3D model reconstruction and rapid prototyping. To complete a contour construction, a local search method and a contour identification algorithm have been also developed as the supplementary algorithms to track contour, search a junction, and identify group of contours. The proposed approach can be used for parts that compose of regular surface whose edges are clearly presented on the orthographic views (e.g., plan surfaces, conical surface, and ruled surface that their cross-sectional contours are parallel with the xy plane). It has been implemented in LabVIEW. Since the only input required is a digital image of the drawing, this approach supports collaboration from remote place, and can be further developed to be an interactive tool that allows contour modification. |
