The formability of aluminum sheet can be improved considerably by increasing the temperature. At elevated temperatures, the mechanical response of the material becomes strain rate dependent. To accurately simulate warm forming of aluminum sheet, a material model is required that incorporates the temperature and strain rate dependency. In this paper, the dislocation based Alflow hardening model ...

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...

Process planning is the systematic determination of the sequence of the operation by which a product is to be manufactured economically and completely. Today both CAD and CAM are well developed as two islands of automation. CAPP is the link between CAD and CAM. Computer aided process planning play a key role in computer integrated manufacturing. In manual process planning, the process planner p...

This study was back grounded by students’ mathematics learning outcome which was low in the topic of fraction addition, so the solution was needed to enhance students’ learning outcome. The use of drawing media was thought as one right solution. Drawing media is a tool used as mediator to deliver information in the form of drawing. This drawing media is used to bridge student level thinking whi...

a new method for increasing ldr in deep drawing is application of anti-lock braking system (abs) on blank holder. in this method, instead of applying a constant force on blank and control the metal flow, the abs system holds and releases the blank several times (20 to 50 times) which results increasing ldr. this study investigates the effect of different parameters of abs on improving the condi...
