Computer Support in the (Re) Design of Mechanical Products

Concepts are proposed to improve the computer support in the (re)design of mechanical products. These concepts are combined with a proposal for an improved link between CAD and CAPP systems. The concepts resulted from a methodic design approach aiming at the design of a re-design support system. Findings from literature, previously conducted research and an object oriented design approach have been taken into account. The concepts incorporate a mixed top-down/bottom-up design strategy. The multiple views problem arising from the use of design and process planning features is dealt with differently when compared with previously published methods. To solve the multiple views problem it is proposed not only to consider the different form features at component level but to also use abstract features and assembly relations in order to yield manufacturing form features. Prototype implementations are under development to evaluate the concepts presented in this paper. Key word codes: I.1.2.1, I.3.5., D.1.5.
