Modeling design objects in CAD system for Service/Product Engineering

Modeling design objects in CAD system for Service/Product Engineering

This paper proposes a new type of service CAD system utilized in Service/Product Engineering (SPE), a much-needed and novel engineering discipline within the background of servicification. In this research a design-object model was defined, and a prototype named Service Explorer was implemented. The model represents critical concepts such as value, costs, functions either of products or of serv...

Representation and CAD Modeling of Heterogeneous Objects

This paper presents a modeling scheme for objects containing multiple materials or functionally graded materials (FGM), i.e. heterogeneous objects. The material composition variations under this modeling scheme are controlled by some reference features termed as “grading sources”. The “grading source” gathers the type of grading, position of grading and a material grading function for controlli...

A Framework for Cad Modeling of Heterogeneous Objects

The conventional CAD modeling approaches only provide geometry and topology of the object but do not contain any information with regard to the materials of the object and so can not be used for the fabrication of heterogeneous objects (HO) through rapid prototyping. A CAD modeling approach using voxelization based material model is represented for the fabrication of HO with simple object geome...
