S. Myung et Sh. Han, Knowledge-based parametric design of mechanical products based on configuration design method, EXPER SY AP, 21(2), 2001, pp. 99-107
Parametric modeling and configuration design methods are key technologies f
or mass customization in manufacturing. This paper describes the parametric
modeling process of machine tool, and proposes a framework which parametri
cally models a machine tool assembly based on a design expert system. The c
oncept of design unit, which is one level higher than functional feature, a
nd the parametric modeling concept with functional features have been propo
sed. The domain knowledge in the knowledge-base has been mapped to the geom
etry of the CAD system. A design expert system to redesign assemblies of a
machine tool has been implemented, because commercial CAD systems cannot ha
ndle the parametric design of assemblies. This system consists of a commerc
ial expert system shell, a design knowledge-base, and a commercial CAD syst
em with an API program. The API program interfaces the expert system with t
he CAD system through a GUI. (C) 2001 Elsevier Science Ltd. All rights rese
