After that, the process of die development was studied according to the sequence of die components, i.e., die structure, machining condition for die making, die materials, heat treatment of partially die components, and so on.
Other die components include cores and slides.
In this study, modeling of strip layout and die components with the Mechanical Desktop commercial program, standard components selection and strip process layout drawing with the Auto-LISP, CAD/CAM application, ordinary machine tool operating, and measurement microscopic cracking deformation is done.
The proposed system utilizes interfacing of AutoCAD and AutoLISP for automatic modeling of die components and die assembly.
A semiskilled and even an unskilled worker can easily operate the system for generation of drawings of die components and die assembly.
The system is capable of automating all major activities of design of progressive die such as checking the design features of sheet metal parts, design of strip-layout, selection of progressive die components, modeling of die components and die assembly, and selection of materials for progressive die components.
The proposed system is capable to automate all major activities of design of deep drawing die such as manufacturability assessment of deep drawn parts, design of strip-layout, process planning, selection of die components, and modeling of die components and die assembly.
The die components (die insert, upper die, bottom die and ejector) were produced from hot-work tool steel AISI H13.
Besides, the interaction behaviors between die components are also taken into account to reflect the real contact evolution.
In maintenance and repair work, the process is commonly used to repair tools and dies, especially components made of aluminum and magnesium.
