The extensive number of engineering drawing will be referred for planning process and the changes will produce a good engineering design to meet the demand in producing a new model. The advantage in reuse of engineering designs is to allow continuous product development to further improve the quality of product development, thus reduce the development costs. However, to retrieve the existing en...

The competition among sheet-metal-forming manufacturers in recent years has become more severe. Many have survived by cutting their production costs. Increasing the formability, which could reduce costs, is focus of many and engineers. In present research, to increase formability over limiting drawing ratio (LDR) cylindrical deep-drawing process, application oleophobic coating proposed. An SUS3...

This paper argues that the role of Computer Aided Design (CAD) should be to enhance and extend paper-based working, rather than to replace it. Current CAD tools are little used in the early stages of designing. Paper is heavily used, with its physical properties supporting work practices that are not possible with CAD. This paper presents implications for the design of new computer-based tools ...

Abstract During deep drawing processes of fiber metal laminates, such as the newly developed in-situ hybridization process, fibers and sheets come into contact while dry fabric is infiltrated by a reactive matrix system. The viscosity increases polymerization starts during deep-drawing. In laminate drawn thermoplastic system injected glass layer in resin transfer molding process. forming lamina...

Through the continuing trend of miniaturization new cost efficient and fast methods for processing small parts are required. In this paper a new non-mechanical process for the forming process of micro deep drawing is presented. This new deep drawing process utilizes a laser initiated plasma shock wave at the target, which forms the sheet. Several pulses can be applied at one point and therefore...

In this paper a low cost knowledge base system (KBS) framework is proposed for design of deep drawing die and procedure for developing system modules. The task of building the system is structured into different modules for major activities of design of deep drawing die. A manufacturability assessment module of the proposed framework is developed to check the manufacturability of deep drawn par...

in the present work, the effects of changing punch and the die radius on several process parameters involved in deep drawing of aisi 304 steel have been studied. deep drawing process of a cylindrical cup was simulated and analysed by numerical modeling. the results were compared with those of obtained from a serie of experimental cupping tests. the comparison shows that: maximum drawing force d...
