A Sheet Metal Forming (SMF) process, especially deep drawing, is one of the manufacturing processes that commonly used in automotive industry. Compared with casting and forging, SMF process has several advantages, including lesser weight materials broader variations shape can be made. The most important problems wrinkling phenomenon tearing sheet products. wrinkle tear occurs because mechanical...

designers draw diagrams to think about architectural concepts and design concerns. scientists are interested in programming computers to recognize and interpret design diagrams to deliver appropriate tools for the design task at hand. researchers conducted empirical studies to find out if designers share drawing conventions when designing. the experiment results show that designers use differen...

Rapid tooling is a methodology which aims to integrate additive manufacturing into the production of tools be used in casting, forming or machining processes. In forming, rapid applied metallic plastic that guarantee good performance small- and medium-sized batch production. However, most punches tested date have dimensions measured millimeters are therefore unsuitable for typical real-world in...

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 this paper, rod drawing process of strain-hardening materials is investigated by analytical, numerical and experimental methods. The classic upper bound solution, based on the assumption of perfect plasticity, has been extended to consider the work-hardening of the material during the drawing process. For a given process conditions and mechanical properties of the rod material, the power ter...

there are many parameters that affect the sheet hydroforming process such as fluid pressure, material properties, interfacial friction between blank and tool surfaces, etc. in this paper, a fem-based taguchi method is used to determine the effects of forming parameters on the quality of part formability in the process of hydrodynamic deep drawing assisted by radial pressure. four important form...
