A component made up of a perfect combination of different materials (most often including homogeneous materials and three different types of heterogeneous materials, i.e., composite materials, functionally graded materials, and heterogeneous materials with a periodic microstructure) in its different portions for a specific application is considered to be a component made of a multiphase perfect material. To design and represent such components, a corresponding computer-aided design method and a CAD modeling method have been developed. Although, there is no existing manufacturing method and facility for such components. Their fabrication entails four steps described in this paper: analysis of the requirements of their manufacture; review of the currently available layered manufacturing, micro-fabrications, and hybrid manufacturing technologies; presentation of a new hybrid layered manufacturing technology (including its manufacturing process and the principle scheme of its corresponding manufacturing facilities); and implementation of the manufacturing simulation by means of virtual manufacturing technology. 相似文献

Shape Representation and Interoperability for Virtual Prototyping in a Distributed Design Environment 总被引:1,自引:3,他引:1
J.Y. Lee 《The International Journal of Advanced Manufacturing Technology》2001,17(6):425-434
Internet technology opens up another domain for building a future CAD/CAM environment. The environment will be global, network-centric,
and spatially distributed. In this paper, we present an approach to network-centric virtual prototyping (NetVP) in a distributed
design environment. The presented approach combines the current virtual assembly modelling and analysis technique with distributed
computing and communication technology for supporting virtual prototyping activities over the network. This paper focuses
on shape representation and interoperability of product models for distributed virtual prototyping. STEP standard and CORBA-based
interfaces allow bi-directional communication between the CAD model and the virtual prototyping model, which makes it possible
to solve the problems of interoperability, heterogeneity of platforms, and data sharing. STEP AP203 is used as a means of
transferring and sharing product models. In addition, Attributed Abstracted B-rep (AAB) is introduced as 3D shape abstraction
for trans-parent transmission of 3D models and for the maintenance of naming consistency between CAD models and virtual prototyping
models over the network. 相似文献
