Key technologies of "zero die trial" design system for aluminum profile extrusion①
Trans. Nonferrous Met. Soc. China, Aug. 2004, Vol. 14 No.4，-0001，（）：
Aluminum alloy profile parts are widely used in the fields of aviation, equipment, automobile and ornamental industries. The construction method for "zero die trial" intelligent design system of aluminum extrusion die was studied based on KBE idea. An object-oriented knowledge language AEKL(Aluminum Extrusion Knowledge Language) was developed to construct intelligent knowledge model with three methods, frame, parameters and rules. On the aspect of knowledge reasoning, case-based reasoning was employed in addition to traditional rule-based reasoning method. API provided by CAD N17platform was used in geometry disposal. Finally, the corresponding protoyping system was established and an design example was shown.
