Abstract
A design system of dies for hot extrusion of structural shapes such as Z's, L's, T's, U's and H's from aluminium alloys was developed in this study. The developed design system of dies is based of estimated die design rule system. The design rules for die design are obtained from the handbooks, plasticity theories and relevant references. The environment of the system is AutoCAD and AutoLISP, the graphic programming language was used for the configuration of the system. This system includes five major modules such as section shape design module, die opening number module, die opening layout module, die correction module and die bearing design module that are used to determine design variables. This system would be used to design of dies for hot extrusion from aluminum alloys and widely used in manufacturing course.
