FEATURE DRIVEN ASSOCIATIVE PART AND MACHINING PROCESS MODELS

摘要

This paper describes a research for associative integration of part and pan manufacturing modeling. In order to gain associative models, the authors analyzed effects of changes of part models on manufacturing process models. Also they analyzed how part manufacturing and production constrain part design. The applied modeling is based on generic Petri net representation of manufacturing models that facilitates handling of process variants by using of the same process model. The modeling assumes unified solid model with topology controlled identification of surfaces and reorderable form feature based part model. The paper is organized as follows. Firstly basic concepts and objectives of the integrated modeling research are introduced. Following this, relationships between part and part manufacturing processes are detailed. Next handling of effects of part model changes and implementation of the proposed modeling are discussed. Finally, contribution to enhancement of capabilities of present day CAD/CAM is concluded.
