Design Decision Automation Support through Knowledge Template CAD Model

ABSTRACT

Today industries and companies are trying hard to reduce lead times and costs for new products, in order to satisfy customer requirements and maintain design quality. This paper presents the procedure and methodology to develop Knowledge template CAD model. This template is an “intelligent” CAD model which replaces the design library usually in the form of database. In this work the Knowledge Template (KT) is designed using Knowledge Base Engineering (KBE) elements such as design constraints, design rules, expressions, Graphical User Interface (GUI) and programs. The proposed KT gets automatically configured to fit for specific context (best design solution) according to the user input. The proposed methodology provide decision support system and tool to help the customer to choose promising design alternatives from KT according to their needs and desires. Design of wheel rim is presented, as an example, to validate the proposed concept of KT. With the proposed KT, it is possible to achieve direct interaction between the user and the CAD model so as to simplify design process and avoid re-design and re-modeling of product.
