In this thesis, a strip layout drawing of LCD S/C (shield case) was prepared. In the press die, strip layout drawing is a major factor that decides the mass production of a product. The 3D CAD/CAM system was applied for the easy correction of the interference factor with other parts to be mounted. The material use ratio was enhanced to 60.17% by optimizing the blank layout and strip layout in double width array. Furthermore, the flatness of the product was made to fit the requirements by adding the bidding process intensively on the notching part where the occurrence of the change in shape is expected owing to the thin material. For the 3D CAD/CAM software, Unigraphics NX3.0 was used. The strip layout drawing was prepared in 12 processes.

Strip layout design in progressive die is an important factor that determines the applicability of mass production. In this study, the layout design of bracket strips used fer automobiles was executed. The strip layout design was made in 3D with the use of Cimatron die design, an automation module rather than a 3D modeling module. Blank layout has been optimized through a layer arrangement of the wide run positioning inside carrier (double-row and two-pass type). The 3D CAD/CAM software used was Cimatron Die Design; the strip layout design was completed in ten processes.

The This research paper deals with research on the 3D strip layout design of HEV UV terminal by utilizing the Cimatron Die Design, an automation module. To ensure smooth stamping of the product, strip layout was corrected for 33.5 degrees of slope, and blank layout of the double-width, 1-line, 1-pull out inner carrier was then optimized as a single arrangement. To mass-produce two different terminals from one common die, 3D strip layout design and die design were completed in 29 different processes.

This paper describes a research work of developing a computer-aided design and machining of irregular shaped-sheet metal product for blanking or piercing operation. An approach to the CAD/CAM system is based on the knowledge-based rules. Knowledge for the CAD/CAM system is formulated from plasticity theories, experimental results and the empirical knowledge of field experts. The system has been written in AutoLISP on the AutoCAD and in customer tool kit on the SmartCAM with a personal computer and is composed of nine modules, which are input and shape treatment, flat pattern-layout, production feasibility check, blank-layout, strip-layout, die-layout, data conversion, modelling, and post-processor module. Based on knowledge-based rules, the system is designed by considering several factors, such as material and thickness of product, complexities of blank geometry and punch profile, diameter and material of a wire, and availability of press. This system is capable of generating NC data automatically according to drawings of die-layout module. Results which are carried out in each module will provide efficiencies to the designer and the manufacturer of blanking or piercing die in this field.

This paper describes some research works of computer-aided design of blanking and piercing for stator and rotor parts and irregularly shaped sheet metal by press. An approach to the system is based on knowledge based rules. The process planning system by considering a blank layout for nesting of irregularly shaped sheet metal and an improved strip layout for stator and rotor parts and irregularly shaped sheet metal is implemented. Using this system, design parameters(utilization ratio, slitting width, pitch, working order, die blank shapes) are determined and output is generated in graphic forms. Knowledges for blank layout and strip layout are extracted from the plasticity theories, handbooks, relevant references and empirical know-hows of experts in blanking companies. The implemented system provides powerful capabilities for process planning of stator and rotor parts and irregularly shaped sheet metal.

In this study, the bracket for car was designed in 3D using Cimatron Die Design, one of the automatic modules. To facilitate the stamping of the product, the layout of the strip was adjusted slightly. The blank layout of the double-width, 2-line, 2-pull out inner carrier was then optimized as a single arrangement. 3D design was completed in 11 processes.

It is important factor to design the strip layout drawing according to product properties in press die design. Press dies are important processes in production such as a car component, house electronics, computer parts etc. In this paper, the strip layout of parts was designed for transfer dies. Results of this study can be modify the punch, trim position and notching shapes of strip layout. Utilization ratio was 70.3% by conducting piercing and notching for scrap design and materials were arranged with wide width of blank layout.
