Abstract:
Logic components are used to support the conceptual design.
Taking the stamping die structure as the research object,
several logic components are defined for the conceptual die
construction design. A new method-logic assembly modeling is
presented to satisfy the characteristic of the top-down die
design process. Representing shapes and spatial relations in
logic can provide a natural, intuitive method of developing
complete computer systems for reasoning about die construction
design at the conceptual stage. This method can reflect the
designer's thought clearly and provide the designer with a test
bed for generating alternatives and performing reasoning work at
the conceptual die design stage.
Key words: CAD Conceptual design Die Logic component Logic assembly model
