This paper presents a research work of a
computer-aided die design system for die casting. The
proposed system consists of seven distinct modules.
Through these modules, the die designers are able to
create a die casting die from a product part model. It is a
user-friendly system that allows both experienced and
novice die designers to easily accomplish the task of die
design.The practical goal of this research is twofold:
(1) to develop a system that integrates the different
stages of die design process and (2) that at the same time
facilitates the editing of die casting design during or after
the course of the design process. The approach undertaken
in this research includes (1) feature-based and
constraint-based modelling, (2) parametric design and
(3) a geometric and topological information extraction
technique from a B-rep model. A prototype system has
been developed using this approach and the system is
able to aid the automation of the die casting die design
process, thus improving the efficiency and quality of,
and reducing the cost of die design for die casting.
